ESPN College Football

When you think Big Ten football, what usually comes to mind is big, corn-fed Midwestern players and bruising offenses. The kind of place that would be perfect for a tight end.

But the 2011 season was a little lackluster for that position in the league, at least as far as the passing game goes. Sure, Northwestern's Drake Dunsmore and Wisconsin's Jacob Pedersen were Mackey Award semifinalists, but those two and Michigan State's Brian Linthicum were the only two tight ends in the conference to record more than 25 catches. Some guys we expected to have big years, like Nebraska's Kyler Reed, Minnesota's Eric Lair and Indiana's Ted Bolser, were nearly invisible on the stat sheet. And there was certainly no one who rose the level of recent Big Ten stars like Dallas Clark, Matt Spaeth, Travis Beckum, Lance Kendricks or Dustin Keller.

Dunsmore, who won the league's inaugural Kwalick-Clark tight end of the year award, and Linthicum have both graduated. Yet 2012 is shaping up as a potentially big season for tight ends across the league.

Some of it has to do with changing offenses and playcallers who love utilizing the tight end. Urban Meyer made a star out of Aaron Hernandez at Florida and could do the same with Jake Stoneburner, who started off blazing hot last year before the Ohio State offense forgot about him. With the Buckeyes searching for playmakers, expect Stoneburner to be utilized heavily in 2012.

"Seeing Hernandez make all those plays makes someone like me pretty happy," Stoneburner told Adam Rittenberg last month. "It's something I've been waiting for since I graduated high school, being able to go out there knowing you're going to get the opportunity to get the ball more than once or twice a game. "

Bill O'Brien coached Hernandez and Rob Gronkowski as offensive coordinator with the New England Patriots, which featured the tight end as much as anybody in football. Now O'Brien is at Penn State, where tight ends have mostly been an afterthought. That will change quickly.

"That’s a very important part of what we’re going to do offensively,” O’Brien told reporters in March. “Obviously, the last two years in New England taught me a lot about the use of a tight end, multiple tight ends.”

At Iowa, new offensive coordinator Greg Davis is raving about sophomore C.J. Fiedorowicz, a 6-foot-7, 265-pounder who began to emerge late last season as a weapon. With an uncertain running game and an excellent passer in quarterback James Vandenberg, Fiedorowicz could follow in the footsteps of Clark and Tony Moeacki as breakout Hawkeyes tight ends. Coincidentally, Iowa's new offensive line coach is Brian Ferentz, who coached the tight ends with the Patriots last year.

“You’ll see the tight ends playing outside sometimes,” Davis told the Des Moines Register during spring practice. “Used to seeing them in motion, but there will be motion in wide receiver sets in some situations because they’re tough match-ups.”

Wisconsin returns one of the best tight ends in the country in Pedersen, who had led Big Ten tight ends with eight touchdown catches a year ago. Bret Bielema is also excited about the depth at the position, with veterans Brian Wozniak and Sam Arneson, redshirt freshmen Austin Traylor and Austin Maly and Pittsburgh transfer Brock DeCicco. Given the inexperience at receiver outside of Jared Abbrederis, the Badgers could look to throw to their tight ends even more this season.

Indiana's Bolser had only 14 catches last year, but he was one of the stars of the spring for the Hoosiers. An improved passing game should help him become more of a factor. Purdue likes the depth it has at tight end, led by Gabe Holmes and Crosby Wright.

“A year ago it was one of the leanest positions on our football team," Boilers coach Danny Hope told reporters in the spring, "and now I think going into the season that the tight end position is going to be one of our strengths.”

Reed's numbers dropped last year, but he still led Nebraska with an average of 17.1 yards per catch. He and fellow senior Ben Cotton form a nice tandem of targets for Taylor Martinez. Michigan State must replace Linthicum but is optimistic about 6-foot-5, 280-pound Dion Sims, who practiced this spring with a cast on his hand. Sims could provide a safety valve for new quarterback Andrew Maxwell early on as the Spartans break in some green receivers.

Minnesota's Moses Alipate will at least be a curiosity as a former quarterback who grew to 290 pounds. Michigan needs Brandon Moore or someone else to step in for Kevin Koger, while Illinois' Jon Davis could have a different role in the team's new spread offense after a promising freshman campaign. Whoever replaces Dunsmore for Northwestern should get a lot of touches.

Tight ends could play an important part of many Big Ten teams' attacks this fall. Just as it should be.

In his first year as Indiana's head coach, Kevin Wilson took a standoffish position about how the team was viewed from the outside.

In our conversations, he never hesitated to point out where Brian Bennett and I had his Hoosiers projected on the Big Ten blog (at or near the bottom of most rankings). He had an infamous appearance on an Indianapolis sports radio show that had taken some not-so veiled shots at the Indiana program. He didn't deny the program's mostly horrid history, but he got fed up with it being used against the team going forward.

His team then proceeded to feed right into that history, going 1-11 with zero wins against FBS competition. A program viewed as one of the weakest in the FBS managed to take a step back.

Wilson is taking a slightly different approach heading into his second year at Indiana. He knows where Indiana will be projected heading into the fall, and he understands why the forecast is bleak. But he also knows how vital it is for the Hoosiers to begin climbing out of the canyon and raising expectations both inside and outside the program.

From The (Bloomington) Herald-Times (subscription required):

"This year is a fight year," Wilson said. "We've got to fight. We've got to establish some credibility. If we lay an egg, then it's just a vicious cycle that can go right down the toilet. It's a critical year. And the bottom line is that, at least at some point in time, we've got to win games."

I love hearing this from a coach in the second year of a seven-year contract. Indiana gave Wilson time to get things right -- more time than most first-time head coaches receive. But Wilson understands the shift needs to take place sooner rather than later.

He's taking accountability to make sure improvement takes place in Bloomington.

"No aspect is satisfactory," he said, "when you're 1-11."

But he said he's learned some things about being a head coach after a year on the job.

"I have to do a better job coaching, and be in a position to do that," he said. "As I evaluate my own weaknesses and strengths, maybe the best thing I have in the background is just being a good, solid football coach. Hopefully, we can get the whole organization on the same page, so I can get back to being more of a football coach. Last year, I could have done a better job of time management, of leadership to help those people developing our program, and therefore allowing me the freedom to coach."

The transition from top assistant to CEO (head coach) can be rocky for some, and while Wilson will have more on his plate than direct coaching, this statement is encouraging to hear.

Wilson is never going to be Mr. Rah-Rah. His personality and style will turn off some, especially those accustomed to hearing what they want to hear from a coach, even if it's not true.

I love his approach. I've known Wilson for a long time -- back to his days as a Northwestern assistant, and mine as a Northwestern student reporter -- and I've always appreciated his bluntness and candor. He doesn't hold back, and you always know exactly where he stands on a topic.

Regarding the 2012 season, he knows it's big. He's willing to be accountable. He wants to lead the fight. Indiana fans should be excited.

The book is closed on spring football in the Big Ten, but what did the chapters reveal? Although no games are played during the spring, which fuels optimism for all 12 teams, the 15 practices provide clues for the upcoming season. The Big Ten saw few major injuries to key players, some good news (the NCAA declaring Michigan State WR DeAnthony Arnett eligible for 2012) and some potentially troubling signs.

It's time to revive the power rankings coming out of the spring. We see separation with the top two teams, while Nos. 3-5 are closely matched. The same holds true for Nos. 7-10.

Here they are ...

1. Michigan State: The Spartans' defense looks like the single best unit in the Big Ten entering the season. Spring practice only enhanced our opinion of Pat Narduzzi's group, which has no shortage of stars. While the passing game needs work, Arnett's presence should help, and the Spartans will rely more on their run game with Le'Veon Bell and an improved offensive line.

2. Michigan: Quarterback Denard Robinson and Fitzgerald Toussaint, who affirmed himself as Michigan's top tailback this spring, form arguably the Big Ten's most dangerous backfield tandem. If Michigan can fill some key pieces on both lines, where there was some shuffling this spring, it will be back in the BCS bowl mix and among the favorites to win the Big Ten crown.

3. Wisconsin: It seems hard to fathom, but Montee Ball appeared to take his game to an even higher gear this spring. The Badgers' star running back will fuel the offense again, although quarterback remains a question mark as Maryland transfer Danny O'Brien arrives this summer. Wisconsin still needs more playmakers to emerge on the defensive line and in the secondary.

4. Nebraska: Tough call on this spot, but the Huskers return their core pieces on offense from a 9-4 team. Footwork-conscious quarterback Taylor Martinez received good reviews this spring, and he should be more comfortable in Year 2 at the helm of Tim Beck's offense. Coach Bo Pelini thinks the defense will be improved and potentially deeper, although the Huskers lose a lot of star power on that side of the ball.

5. Ohio State: There were few dull moments in Ohio State's first spring under Urban Meyer, who began installing an offense unlike any seen in Columbus. After resembling a "clown show" early on, the offense made strides and quarterback Braxton Miller looks like a strong fit for the system. An improved defense, led by linemen John Simon and Johnathan Hankins, should buy the offense some time to get acclimated.

6. Penn State: New coach Bill O'Brien ushered in a historic spring in Happy Valley, and Penn State players for the most part embraced the many changes taking place. The Lions still don't have a quarterback, but they have an excellent running back in Silas Redd and an improved offense line that pleasantly surprised O'Brien this spring. Penn State's defensive front seven, led by linebacker Gerald Hodges and tackle Jordan Hill, might need to carry the team at times.

7. Purdue: Fourth-year coach Danny Hope thinks this is clearly his best team in West Lafayette, and with 18 starters back, it's easy to see why. The Boilermakers are one of the Big Ten's deepest teams at positions like quarterback, defensive tackle, running back and cornerback. Purdue must continue to absorb the new defense installed by Tim Tibesar and fill some key gaps along the offensive line.

8. Iowa: Although Iowa's changes this spring didn't make national headlines like the ones at Penn State and Ohio State, they were very significant. New offensive coordinator Greg Davis began installing a more up-tempo and multifaceted offense that seems to be clicking with senior quarterback James Vandenberg. Jordan Canzeri's ACL injury once again clouds the picture at running back entering the summer, and Iowa needs its young defensive line to grow up in a hurry.

9. Northwestern: The Wildcats showcased one of the league's top wide-receiving corps this spring, and if Kain Colter can improve his passing, the offense should surge. Defense has been Northwestern's bugaboo in recent years, and young players like end Deonte Gibson and cornerback Nick VanHoose stepped forward this spring. It's crucial for the defense to keep making progress if Northwestern wants to maintain its bowl streak.

10. Illinois: There's little doubt Illinois will be a defense-driven team, and the Illini look loaded in the front seven with players like end Michael Buchanan, who turned in a very strong spring, as well as tackle Akeem Spence and linebacker Jonathan Brown. An offense that flatlined late last season began learning a new system this spring and still lacks playmakers at running back and wide receiver. Running back Josh Ferguson's spring-game performance is encouraging.

11. Minnesota: The second spring of the Jerry Kill era brought greater comfort for both players and coaches alike. Quarterback MarQueis Gray made strides in his second spring session as the starter, although the Gophers are still looking for more weapons to surround No. 5. The defensive line should be an improved group after several lifeless seasons. Minnesota still needs to develop depth in the secondary and at wide receiver.

12. Indiana: After playing an insane number of freshmen in 2011, Indiana began to reap the benefits this spring. An influx of junior-college defenders, including linebackers David Cooper and Jacarri Alexander, also should boost a unit that needs all the help it can get. The Hoosiers have some nice building blocks on offense at both quarterback (Tre Roberson) and running back (Stephen Houston, Isaiah Roundtree), but they still have a lot of work to do before the season.

Spring practice is a time when coaches install new schemes or just instill the fundamentals. The most exciting part of spring practice is potential new stars emerge, with newcomers or former reserves turning heads with their performances.

Some of these guys will fade back into the shadows come fall. But others will be making major contributions on a field near you. Here's a list of some players who had breakout springs:

Josh Ferguson, RB, Illinois: Redshirted last year after a hamstring injury, Ferguson blew up for 130 yards and caught six passes in the Illini spring game. He flashed his speed and versatility for an offense that desperately needs playmakers in its new spread attack. Ferguson should be in line to get a lot of touches in 2012.

Michael Thomas, WR, Ohio State: A true freshman who enrolled in January after spending a year in prep school, Thomas suddenly became Braxton Miller's favorite target in the spring game, hauling in 12 catches for 131 yards. Like Ferguson, he gave a glimmer of hope to a position that was sorely in need of a boost for the Buckeyes, and he'll get a shot at plenty of playing time right away.

Darien Harris, LB, Michigan State: Few people were talking about Harris at the start of spring, especially since the Spartans return all three starting linebackers. But with Chris Norman out this spring with an injury, Harris got a bunch of reps and ran with it. Mark Dantonio called the redshirt freshman "one of the exciting surprises of the spring." He'll play this fall, but the question is how much?

Joey Burzinski, OL, Michigan: Even most Wolverines fans had probably not heard of Buzinski, a walk-on freshman, before this spring. But a strong work ethic and a lack of depth on the Michigan O-line helped him make a move until he found himself working with the first string. Burzinski is no lock to start but should see minutes somewhere on the line and is a great story.

Bill Belton, RB, Penn State: Belton was a highly-regard recruit who started to make an impact at the end of last season. Moved to full-time running back this spring, he responded by making a lot of plays and adding depth to a spot that was extremely thin behind Silas Redd. Belton's versatility should help him become a useful weapon in Bill O'Brien's offense.

David Cooper, LB, Indiana: There's no question that the Hoosiers desperately needed some help on defense, and head coach Kevin Wilson scoured the junior college ranks for a talent injection. Cooper, along with Jacarri Alexander, proved he could run and tackle this spring, and he also brought a high energy level that rubbed off on his teammates. He's slated to start at middle linebacker and hopefully bring some improvement to the overall defensive effort.

C.J. Fiedorowicz, TE, Iowa: He was a hyped recruit, and now Fiedorowicz might be about to show why. A matchup nightmare at 6-foot-7 and 265 pounds, the junior is expected to play a major role in new offensive coordinator Greg Davis's offense, and James Vandenberg has to love having such a big target.

Frankie Williams, S, Purdue: By the end of last season, Danny Hope regretted his decision to redshirt Williams because he felt he could have contributed at cornerback. Williams moved to safety this spring and got the start there in the spring game. The Boilers are deep at corner but could use a little help at safety, and Williams looks ready to fill that need.

This isn't exactly surprising news, but Big Ten schools are among the biggest spenders -- and earners -- in all of college athletics, according to a new database compiled by USA Today.

The newspaper collected the expenses and revenues for Division I athletic programs in 2010-2011, the most recent year for which public schools' filings with the NCAA were available. The study showed that everything is bigger in Texas, including sports spending; the Longhorns outpaced every other school with a $133.7 million budget and more than $150 million in revenue.

But Big Ten schools also ranked high among the biggest spenders, with seven teams in the top 16 nationally. Here is how they stacked up nationally in operating expenses:

2. Ohio State: $122.3 million

3. Michigan: $111.8 million

6. Penn State: $101.3 million

9. Wisconsin: $95.6 million

12. Iowa: $93.4 million

14. Michigan State: $84.5 million

16. Nebraska: $83.7 million

22. Minnesota: $78.9 million

26. Illinois: $77.7 million

29. Indiana: $71 million

41. Purdue: $66.2 million

(Note: Information for Northwestern, which is a private school, was not available).

Only the SEC -- another surprise, right? -- has more big spenders than the Big Ten, with eight schools reporting more than $80 million in expenses

The USA Today report also said that only 22 athletic programs turned a profit in 2010-11, but 10 of the 11 Big Ten schools surveyed were in the black, while Minnesota broke even (Thanks, Big Ten Network). Penn State had the biggest profit, at nearly $15 million, while Michigan and Ohio State each reported revenue of about $11 million more than their expenses.

Another interesting part of the report is how much subsidy each athletic program receives from its school, in the form of student fees and other university support. Four Big Ten athletic programs -- Ohio State, Nebraska, Penn State and Purdue -- receive no school subsidy, something only seven Division I programs can claim. Meanwhile, Michigan ($272,000) and Iowa ($564,000) get less than a million, ranking in the bottom 10 nationally for subsidy support.

Here's a look at the subsidies other league programs receive:

Minnesota: $7.8 million in subsidies (9.9 percent of total operating budget)

Wisconsin: $7.2 million (7.5 percent)

Illinois: $4 million (5.1 percent)

Michigan State: $3.7 million (4.3 percent)

Indiana: $2.7 million (3.8 percent)

The USA Today report paints a picture of the haves and have-nots in college athletics and even suggests that the wild disparity between the upper echelon and the bottom schools could lead to a split in college football.

But while many schools' athletic programs are struggling to make ends meet or need vast support from their universities to keep the lights on, the Big Ten looks extremely healthy in its finances.

Big Ten bloggers Adam Rittenberg and Brian Bennett will occasionally give their takes on a burning question facing the league. We'll both have strong opinions, but not necessarily the same view. We'll let you decide which blogger is right.

Today's Take Two topic is this: Last season, defensive tackle was clearly the strongest overall position group in the Big Ten. What position will be the best throughout the league in 2012?

Take 1: Brian Bennett

I'm tempted to go with linebacker, where some high-profile players and future stars are scattered throughout the conference. But my pick is running back.

There's some major star power at the position this year in the Big Ten, starting off with last year's Heisman Trophy finalist and record breaker, Wisconsin's Montee Ball. While Ball is the obvious choice for preseason offensive player of the year, he could get pushed by some other backs, including Nebraska's tough-as-nails Rex Burkhead, who ran for 1,357 yards and 15 touchdowns last season. Even with last year's No. 2 league rusher (Iowa's Marcus Coker) gone, the position is still stacked with guys like Penn State's Silas Redd, who we both think is primed for a huge season; Michigan's Fitz Toussaint, who ran for more than 1,000 yards despite not taking over lead rushing duties until the eighth game of the season; and Michigan State's Le'Veon Bell, who came on strong late last season and looks great this spring.

Purdue has some very capable runners in Akeem Shavers, Akeem Hunt and Doug Gentry, and Ralph Bolden is coming back from an ACL injury. Ohio State has a potentially strong group with Carlos Hyde, Jordan Hall, Rod Smith and freshman Bri'onte Dunn. Stephen Houston showed some good things for Indiana last year, and transfer Isaiah Roundtree had a big spring game. Minnesota is high on junior college import James Gillum. And don't forget James White at Wisconsin, who could start for most teams in the country.

Iowa, Illinois and Northwestern have some question marks at tailback. But overall, running back is where the Big Ten's bread will be buttered this season.

Take 2: Adam Rittenberg

A good choice, Bennett, as the Big Ten returns six of its top seven running backs and would have brought back all seven if not for Marcus Coker's transfer. But my experience covering this league has taught me to never overlook the defensive line. The D-line once again will be the Big Ten's strongest group in 2012.

Sure, the league loses standouts like Devon Still, Whitney Mercilus and Jerel Worthy. But you could substitute the names Aaron Maybin and Mitch King after the 2008 season, or Brandon Graham and Jared Odrick after 2009, or J.J. Watt and Corey Liuget after 2010. The Big Ten always finds ways to reload up front, and this year will be no different. There might not be as many familiar names as there are at running back, but that soon will change.

Let's start off with the top returning linemen, Ohio State's John Simon and Purdue's Kawann Short, both of whom earned first-team All-Big Ten honors in 2011. Both men will contend for All-America honors, and could be potential first-round picks in the 2013 class. Then you have a guy we're both excited about: Michigan State defensive end William Gholston. He's a physical freak, as you recently detailed, and has the potential to dominate games and become one of the nation's truly elite defenders in 2012. I'd also include Penn State defensive tackle Jordan Hill in this group of known commodities with the potential for very big things this season. Penn State's overall depth along the defensive line should be better this year.

Now for some lesser-known names who could have breakout seasons. Let's start at Illinois with defensive end Michael Buchanan and defensive tackle Akeem Spence. Buchanan is poised for a big year, as he showed in Illinois' spring game, while Spence is a next-level player who could follow Liuget's path this season. Speaking of defensive tackles, watch out for Ohio State's Johnathan Hankins, a very big man who can do very big things this season. The Buckeyes' heralded incoming freshmen should only bolster their line.

Michigan loses two standout linemen (Mike Martin and Ryan Van Bergen), but it's hard to imagine the Wolverines falling back much at all up front. Nebraska boasts good depth at the defensive end spot and could see a big year from a guy like Cameron Meredith.

While there are some question marks around the league, including an unproven line at Iowa, teams like Northwestern and Minnesota should be improved up front.

After an offseason jam-packed with change, most players and coaches in the Leaders Division haven't had time to examine anyone but themselves.

"I have no idea," first-year Penn State coach Bill O'Brien said. "I'm only concerned about one program, and that's Penn State."

The Big Ten had three head-coaching changes in the offseason, all of them in the Leaders Division (Penn State, Ohio State and Illinois). Wisconsin, the two-time defending Big Ten champion, had to replace six assistant coaches, including premier playcaller Paul Chryst and offensive line guru Bob Bostad. Purdue replaced its defensive coordinator, while Indiana brought in a new offensive coordinator.

All six teams have some new flavor and the uncertainty that comes with it. All six teams also sense opportunity in what could be a wide-open division race.

"Everybody has new people," Penn State defensive tackle Jordan Hill told ESPN.com. "Even Wisconsin, they've got six new assistants, and in most cases, the assistants are who deal with the players the most. So I feel it's wide open. Not that I don't feel that every year, but it's more than usual."

Wisconsin has reached the past two Rose Bowls and won 32 games during the past three seasons. The Badgers return Heisman Trophy finalist Montee Ball, the Big Ten's offensive player of the year in 2011, and recently added another quarterback transfer in Danny O'Brien, the former Maryland signal-caller.

Although the staff turnover is significant, Bret Bielema has replaced key assistants before, like defensive coordinator Dave Doeren after the 2010 season. There's still a strong case to be made that the Leaders Division title still goes through Mad-city.

"We are the targeted team in the Big Ten because of what we've done the past two years," Ball said. "Everyone is shooting and gunning for us."

Added Bielema: "Everyone thinks it's complacency that's going to affect us, but here at Wisconsin we've become greedy."

Ball lists Ohio State as the team Wisconsin is gunning for, and the Badgers and Buckeyes have a spicy rivalry brewing. Some think Ohio State will end up as the division's top team, but the Buckeyes are banned from postseason play and the Big Ten title game, adding a subplot to the division race.

"We have a great opportunity right now," Purdue defensive tackle Kawann Short said. "We've got a lot of starters coming back. ... Ohio State can't get back in conference championship, so it just gives us a little edge.

"We've got to take advantage of it."

Purdue likely will be a popular pick as a sleeper team in the division. The Boilers return nine starters on both sides of the ball and three quarterbacks -- Caleb TerBush, Robert Marve and Rob Henry -- who have started multiple games. They also have recorded two wins against Ohio State during coach Danny Hope's three-year tenure.

Indiana has a bigger hill to climb after a 1-11 season in 2011. But the Hoosiers are a year older and more familiar with the demands of coach Kevin Wilson and his staff.

"Last year we struggled in my first year, didn't play up to our capabilities," Wilson said. "Hopefully that'll lead to giving ourselves an opportunity to compete with some of those teams as they go through some transition."

While Ohio State can't make it to Indianapolis in Urban Meyer's first year, the other two division teams with new coaches could surprise people. Both Penn State and Illinois have similar profiles, boasting strong defensive front sevens but question marks on offense.

"At this time, everybody is saying the same thing, whether it's Illinois, Ohio State, Wisconsin," Illinois quarterback Nathan Scheelhaase said. "... It really comes down to who’s going to go out there every day and get better, who's going to put in the extra work to be the best football team.

"Everybody wants to be, but ultimately one team is going to do it more so than anybody else."

Our series ranking each position group from the 2011 Big Ten season comes to a close today with the final group, and one that is often overlooked but is always important: special teams.

Special teams is a broad spectrum, so we're combining performances in punting, kickoffs and field goals to come up with each team's position on this list.

And away we go:

1. Nebraska: Boy, did we mess this up in the preseason by ranking the Huskers 11th out of 12. Though we wrote at the time that Nebraska would almost certainly outperform its low rankings, we thought replacing star punter/kicker Alex Henery would be tough. Not really, as Brett Maher was one of the best punters and kickers in the league and the country. Freshman Ameer Abdullah was a star in kick returns, finishing ninth nationally in that category. So just remove one of the ones from that preseason number, and then we've got it right.

2. Purdue: The Boilermakers were mostly mediocre on offense and defense but did some great work on special teams. Freshman Raheem Mostert led the nation in kickoff returns, while sophomore Cody Webster finished second in punting. The strong-legged Carson Wiggs tied Maher for most field goals made in the league, though he still needs to improve his accuracy. Blocked kicks helped secure wins over Middle Tennessee and Ohio State, but Purdue lost on a blocked field goal try at Rice.

3. Penn State: When Anthony Fera returned from suspension and took over field goal duties, the Nittany Lions' special teams became truly special. Fera hit 14 of 17 field goals after Penn State had looked very shaky in that area early in the year, and he was also one of the league's top punters. Chaz Powell and Justin Brown were dangerous return men.

4. Ohio State: The Buckeyes ranked among the top third of Big Ten teams in just about every special-teams category. Field goal kicker Drew Basil made a dozen in a row at one point, and Ben Buchanan was solid at punter. Jordan Hall added some big returns.

5. Michigan State: We ranked the Spartans No. 1 in the preseason, and they came up with some game-changing plays, particularly in the first game against Wisconsin and in the Outback Bowl win over Georgia. But statistically speaking, Michigan State was average in most aspects of the kicking game. But Mike Sadler had some big moments punting, and Keshawn Martin did excellent work on punt returns.

6. Wisconsin: A tough team to rank, as there was both good and bad here. Jared Abbrederis led the nation in punt return average at 15.8 yards per attempt. Brad Nortman was a very reliable punter, while Philip Welch made five of his six attempts at field goals, something the Badgers didn't need very much with Montee Ball assaulting the end zone. But we can't ignore the big special-teams breakdowns against Michigan State and Ohio State that had as much as anything to do with ruining a potential undefeated season.

7. Michigan: The Wolverines weren't outstanding at any one area on special teams, but they proved much better than the No. 12 ranking we saddled them with in the preseason. Brendan Gibbons solidified what looked like a scary place-kicker situation and played a large role (along with brunette girls) in the Sugar Bowl victory. Michigan was also strong in punt returns and kick coverage, though its punting and kickoff returns left much to be desired.

8. Iowa: The good news first: Iowa led the league in net punting, thanks to a strong showing by senior Eric Guthrie in his first year starting. Now the bad: The Hawkeyes ranked second-to-last in kickoff coverage, and Mike Meyer missed six of his 20 field goal attempts, including both tries in the humbling loss to Minnesota.

9. Minnesota: Even without premier return man Troy Stoudermire, who missed most of the year with an injury, the Gophers ranked fifth in the league in kickoff returns, and they led the league in kickoff coverage. But a team that punted as much as Minnesota did in 2011 needed to do better than 11th in the conference in that category. Bonus point for the perfectly executed onside kick in the Iowa win.

10. Northwestern: The Wildcats' defense got the brunt of the blame in Northwestern's losses, but special teams didn't hold up its end of the bargain, either. Northwestern made only six field goals all year and ranked near the bottom of the conference in most categories. The bright spot was a league-best punt return unit.

11. Indiana: Mitch Ewald went 13-of-16 on field goals, but the Hoosiers weren't very good in most other areas. They returned more kickoffs than anyone in the Big Ten -- a product of a crummy defense -- but didn't do enough with them in finishing 108th nationally in that stat.

12. Illinois: Ron Zook didn't help his case to be retained as head coach through the performance of his special teams, a part of the game that was supposed to be his field of expertise. Illinois was simply dreadful in creating advantageous field position, finishing last in the nation in kickoff returns and third-to-last in punt returns. The Illini also weren't very good at kickoff coverage, though at least Derek Dimke made 10 of 12 field goals. Even that was marred by his missed 42-yarder at the end of a 10-7 loss at Penn State.

The Big Ten saw an unprecedented number of coaching changes during the offseason, as three head coaches were dismissed, Wisconsin's staff lost six assistants and many other moves were made. Barring an unexpected change, only four teams -- Michigan, Michigan State, Minnesota and Northwestern -- will return their full staffs intact for the 2012 campaign.

Although the coaching carousel hasn't quite reached its end, Big Ten teams have filled all of their coordinator vacancies for the coming season. The league will have 13 new coordinators at eight different programs.

It's time to pass out quick grades for the coordinator hires (co-coordinators are graded together):

ILLINOIS

Co-offensive coordinators Billy Gonzales and Chris Beatty
Previously: Gonzales was LSU's receivers coach and pass-game coordinator; Beatty was Vanderbilt's receivers coach

Grades

Adam Rittenberg: C

Gonzales and Beatty both are strong recruiters who should help bring talented players to Champaign, but they're both young and unproven as playcallers. They should bolster Illinois' receiving corps, but I'd expect a few growing pains on game days as they adjust to bigger roles with a unit that flat-lined late in the 2011 season.

Brian Bennett: B-

Both are energetic guys who should adapt well to Tim Beckman's style, and both were considered up-and-comers. But as Adam mentioned, neither had led an offense before, so it's hard to give this too high a grade yet.

Defensive coordinator Tim Banks
Previously: Co-defensive coordinator and defensive backs coach at Cincinnati

Grades

Adam Rittenberg: A-

After a very successful 2011 season, Illinois' defense is looking for continuity and Banks can provide it. His aggressive style and pressure packages should translate well for a unit that still has a lot of talent in the front seven with linebacker Jonathan Brown, defensive tackle Akeem Spence and others.

Brian Bennett: B+

Vic Koenning declined to stay, and Jon Tenuta took the job for about 20 minutes before deciding to stay at NC State. As a third choice, Banks is a really nice hire and a better fit, in my opinion, than Tenuta would have been. After a tough first year with a Cincinnati defense lacking depth and experience, Banks did a great job turning that unit around in 2011. At Illinois, he merely needs to keep it going.

INDIANA

Offensive coordinator Seth Littrell
Previously: Offensive coordinator and tight ends coach at Arizona

Grades

Adam Rittenberg: B+

Littrell wasn't the reason Arizona made a coaching change in 2011, as his offense ranked third nationally in passing (370.8 ypg) and 15th in total yards (465.2 ypg). He comes from the fertile Mike Leach coaching tree and should help Indiana's offense become more balanced behind promising quarterback Tre Roberson.

Brian Bennett: A

It isn't easy to hire big-name coaches at Indiana, but Kevin Wilson got a good one as Littrell was left looking for a gig. The addition of Littrell already helped the Hoosiers land promising quarterback Nathan Sudfeld on the recruiting trail.

IOWA

Offensive coordinator Greg Davis
Previously: Offensive coordinator and quarterbacks coach at Texas (didn't coach in 2011)

Grades

Adam Rittenberg: B

Davis is an experienced coach who has coordinated offenses at the highest level and won a national title at Texas. He should help James Vandenberg's development at quarterback. The concern is he has been predictable at times and had his most recent success in a spread system, which Iowa likely won't use.

Brian Bennett: C+

Davis oversaw some record-breaking offenses at Texas, but he won't have the same kind of blue-chip talent at Iowa. Then again, in Kirk Ferentz's system, he won't be asked to generate 50 points per game. He's great with quarterbacks, and Ferentz will feel comfortable with a veteran coach who'll keep things simple. But to hire a guy who'd been out of football for a year was not very exciting for a program that probably could have used a battery recharge.

Defensive coordinator Phil Parker
Previously: Defensive backs coach at Iowa

Grades

Adam Rittenberg: B

Parker knows the Hawkeyes' personnel and brings an energetic personality to the defense, but he's not the big-splash addition some were hoping for after Norm Parker's retirement. Phil Parker has coached defensive backs forever but has yet to serve in a coordinator role. It'll be interesting to see how much he actually tweaks the scheme in Iowa City.

Brian Bennett: B-

Parker knows the Hawkeyes defense in and out, and I doubt much will change with the approach now that he is in charge. There was a curiously long time between Norm Parker's retirement and his successor's appointment, and Phil Parker has never been a coordinator before, so that brings my grade down a notch.

NEBRASKA

Defensive coordinator John Papuchis
Previously: Defensive line coach and special teams coordinator, Nebraska

Grades

Adam Rittenberg: B

Papuchis is a rising star and most likely a head coach in the near future. While I'm tempted to give him a higher grade, he hasn't been a playcaller and is just four years removed from being a football intern at LSU. Inexperience is the only main drawback here.

Brian Bennett: B-

Like Adam said, the grade level is held down here by a lack of previous experience. But every coordinator has to start somewhere, and Bo Pelini has been really high on Papuchis, who has done excellent work everywhere he's been put to use so far. Any growing pains should be offset by the knowledge Pelini can impart as a defensive-minded head coach.

OHIO STATE

Offensive coordinator Tom Herman
Previously: Offensive coordinator and quarterbacks coach, Iowa State

Grades

Adam Rittenberg: B+

Herman is regarded as a rising star and a sharp offensive mind who, with the help of Urban Meyer, will inject some life into a bland Ohio State offense. The only potential drawbacks are that he hasn't proven himself in a big-time job like Ohio State, and Iowa State's offensive numbers from 2011 don't exactly jump off the page.

Brian Bennett: B-

Ohio State fans were probably expecting a bigger name when Meyer promised to bring in the best staff in the country. But Meyer has an eye for offensive talent and will be heavily involved in the offensive game planning himself. Though Herman hasn't done it on a major stage, he'll be working with a lot more talent in Columbus, and this grade could easily prove to be an A in the future.

Defensive coordinator Luke Fickell and co-defensive coordinator Everett Withers
Previously: Fickell was Ohio State's head coach; Withers was North Carolina's head coach

Grades

Adam Rittenberg: A-

There's a lot to like about this pair, as both men return to coaching defense after being put in awkward positions last season. It'll be interesting to see how Fickell fares as the primary defensive playcaller. Withers has a few blotches on his résumé (Minnesota 2007) but brings a lot of experience to the table.

Brian Bennett: A

The head-coaching experience both men got last year should only help their development as coaches, and both are excellent recruiters. My only concern is whether there are too many cooks in the kitchen, but there's no reason to believe that Fickell and Withers won't get along and accept their roles. If so, this should work out really well.

PENN STATE

Defensive coordinator Ted Roof
Previously: Defensive coordinator at Auburn (briefly took Central Florida defensive coordinator job in December)

Grades

Adam Rittenberg: C+

While I loved what Roof did at Minnesota in 2008, his exit from Auburn after some struggles there raises a few red flags. The good news is he steps into a very good situation with Penn State's defense, and he has three good assistants: Larry Johnson, Ron Vanderlinden and John Butler, two of whom (Johnson and Vanderlinden) are holdovers from the previous staff.

Brian Bennett: C

Roof has some very bright spots on his long résumé, but he's also been a serial job-changer whom Auburn fans couldn't wait to see leave town despite the national title. Bill O'Brien could have retained Tom Bradley or promoted Johnson and probably done just as well, if not better. But he has a previous relationship with Roof, so the trust factor should be high.

PURDUE

Defensive coordinator Tim Tibesar
Previously: Defensive coordinator for the CFL's Montreal Alouettes

Grades

Adam Rittenberg: C

Both the change and the hire surprised me a bit, and Tibesar is a bit of a wild card coming back to college football from the CFL. He knows how to face the spread offense, a primary reason Danny Hope hired him, and had some success in Montreal. But his previous FBS stop at Kansas State resulted in some struggles (117th-rated defense in 2008).

Brian Bennett: C-

If Tibesar pans out as a successful defensive coordinator, perhaps Hope will start a trend of teams looking to the Great White North for assistant coaches. I'll give Hope some credit for making an unconventional choice, but I'm a little skeptical about just how well the CFL experience will translate to college.

WISCONSIN

Offensive coordinator Matt Canada
Previously: Offensive coordinator and quarterbacks coach at Northern Illinois

Grades

Adam Rittenberg: B

Canada has extensive coordinator experience, including four seasons in the Big Ten at Indiana, but he has been primarily a spread coach in recent seasons. While he had success running a pro-style system during his first stint at Northern Illinois (2003), he'll have to make some adjustments. The good news: he inherits a lot of talent and understands his main job is to keep the momentum going.

Brian Bennett: B-

I was surprised that Bret Bielema didn't chose someone who was a pro-style disciple through and through given his strong comments about not changing the offense much after Paul Chryst left. As Adam said, Canada knows his stuff and has done some good work as a coordinator. But anytime a coach has to adjust his style to a larger system and not the other way around creates a seed of doubt.

The postseason position rankings are hitting the home stretch, and today we take a look at the Big Ten secondaries. It's a little tricky to evaluate secondary play from 2011. While seven Big Ten teams ranked in the top 18 nationally in pass defense, only two squads ranked in the top 29 in pass efficiency defense.

Nebraska cornerback Alfonzo Dennard was the lone Big Ten defensive back to appear on both the coaches' and media's first-team all-conference squad, so there was some disagreement.

The top seven units are solid, while the bottom three are among the worst in the FBS.

Michigan State once again tops a defensive chart, but the top four or five squads here were all strong in the secondary. Be sure and check out our preseason secondary rankings.

Let's get to the rundown:

1. Michigan State: The Spartans had three of four starting defensive backs — safety Trenton Robinson, cornerback Johnny Adams and safety Isaiah Lewis — selected first-team or second-team All-Big Ten, illustrating the depth coach Mark Dantonio has built in recent years. Michigan State's secondary also continued to be a playmaking unit, recording a league-best 18 interceptions, returning four for touchdowns. The Spartans had five defensive backs record two or more interceptions. Adams will enter the 2012 season pegged as the league's top cornerback.

2. Penn State: Like the other defensive units, Penn State's secondary shouldered a heavy burden because the team's offense struggled for so much of the season. The Lions had veteran leadership with D'Anton Lynn, Nick Sukay and Drew Astorino, and they led the Big Ten and ranked sixth nationally in pass efficiency defense (107.2 rating). Penn State finished third in the league in interceptions (14) and tied with Michigan for the fewest passing touchdowns allowed (12). Sukay earned second-team All-Big Ten honors.

3. Illinois: Although Illinois' strength on defense could be found in the front seven, the secondary held its own as well. The Illini ranked third nationally in pass defense (162.3 ypg), and opposing teams completed just 54.9 percent of their passes against the Orange and Blue. Illinois finished 30th nationally in pass efficiency defense. Although the safety play looked spotty at times, Illinois boasted a strong cornerback tandem in Terry Hawthorne and Tavon Wilson.

4. Michigan: Arguably no single position group in the Big Ten made more dramatic strides than Michigan's secondary, a lightning rod for criticism the previous three seasons. The Wolverines finished 16th nationally in pass defense and 36th in pass efficiency defense. Although they didn't record many interceptions, they tied for the league low in passing touchdowns allowed (12). Safety Jordan Kovacs emerged as an effective blitzer and playmaker and cornerback J.T. Floyd blossomed with two interceptions, eight pass breakups and a forced fumble. Corner Blake Countess is an exciting young talent.

5. Nebraska: The Huskers had the Big Ten's best defensive back in Dennard, who shut down arguably the league's top two receivers (Marvin McNutt, B.J. Cunningham) in Nebraska victories. But the group's overall performance was a bit underwhelming, as opposing teams attacked the deep middle and caused some personnel shuffling. Opposing teams completed just 53.2 percent of their passes against Nebraska, the lowest number in the Big Ten. Hard-hitting safety Daimion Stafford emerged for a group that loses Dennard and veteran safety Austin Cassidy.

6. Wisconsin: For the second straight season Wisconsin displayed good playmaking ability in the secondary, finishing second in the Big Ten with 16 interceptions. Safety Aaron Henry (coaches) and cornerback Antonio Fenelus (media) both received first-team All-Big Ten recognition. The Badgers also played most of the season without one of their starting cornerbacks, Devin Smith. But the unit also had some high-profile lapses at the end of games. Speed also became an issue in the Big Ten title game against Michigan State and in the Rose Bowl against Oregon.

7. Ohio State: The numbers aren't bad -- Ohio State ranked 14th in pass defense and 53rd in pass efficiency defense -- but the Buckeyes seemed to be missing something in the secondary, and throughout their entire defense, for that matter. There were some bright spots, like freshman cornerback Bradley Roby, and some hard hits delivered by safety C.J. Barnett and others. But Ohio State finished just eighth in the league (53rd nationally) in pass efficiency defense, as opposing teams completed more than 60 percent of their pass attempts against the Scarlet and Gray.

8. Purdue: We had high hopes for a group that returned all four starters, headlined by All-Big Ten candidate Ricardo Allen at cornerback. At times, Purdue's secondary looked solid, but the unit's overall performance fell in line with the team's average theme for 2011. Allen struggled to contain some elite wideouts but still finished the season with 81 tackles (62 solo), three interceptions, four pass breakups, a blocked kick and a forced fumble. He and Josh Johnson form an exciting cornerback tandem entering the 2012 campaign.

9. Iowa: Much like Ohio State, Iowa didn't have a typical season on defense, and the secondary had its share of struggles. Iowa had average numbers (58th in pass yards allowed, 72nd in efficiency), and allowed opposing teams to complete 62 percent of their passes. The Hawkeyes saw a big drop-off in playmaking, as they recorded only 10 interceptions and allowed 21 touchdown passes. Safety Micah Hyde earned second-team All-Big Ten honors from the media, while cornerback Shaun Prater didn't have the huge senior season some expected.

10. Northwestern: The Wildcats would finish last in some leagues, but they're the best of a bad bunch at the bottom of the rankings. Despite an All-Big Ten safety (Brian Peters) and a four-year starter at cornerback (Jordan Mabin), Northwestern suffered breakdowns in both scheme and execution. The Wildcats endured a particularly bad stretch to begin Big Ten play, as they couldn't stop Illinois receiver A.J. Jenkins, admittedly got confused against Iowa and let Penn State quarterback Matthew McGloin go off. The secondary has to be a huge priority for Pat Fitzgerald and his staff during the offseason.

11. Minnesota: It's a close call for the last spot, but Minnesota avoids the basement, thanks in large part to safety Kim Royston, who made the most of his sixth season with a team-high 123 tackles. But Royston was the lone bright spot for Minnesota's secondary, which stung from the loss of cornerback Troy Stoudermire to a broken arm. The Gophers recorded the fewest interceptions in the Big Ten (4), and allowed opponents to complete 67.7 percent of their passes, the highest total in the league. Minnesota finished 107th nationally in pass efficiency defense.

12. Indiana: The Hoosiers' historic struggles in the secondary continued in 2011, as they surrendered a league-high 26 passing touchdowns and finished 116th out of 120 FBS teams in pass efficiency defense. Opponents averaged 8.5 yards per completion against an Indiana team that played more freshmen than any squad in the FBS. There's some hope with players like safety-linebacker Mark Murphy and cornerback Greg Heban, and Indiana brings in two junior college defensive backs for 2012.

After taking a look at the Legends Division outlook for spring practice, it's time to turn the focus to the Leaders Division.

Away we go ...

ILLINOIS

Start of spring practice: March 7
Spring game: April 14

What to watch:

• New faces in new roles: Tim Beckman and his assistants get their first chance to work with the players on the field. Beckman retained only one assistant (defensive line coach Keith Gilmore) from the previous staff, so it'll be important for the players and coaches to get acclimated. It's also a big spring for co-offensive coordinators Billy Gonzales and Chris Beatty, both of whom will be primary playcallers for the first time at this level.
• The quarterbacks: Nathan Scheelhaase is a two-year starter, but he'll have to re-establish himself as the team's top option at quarterback. Reilly O'Toole received a decent amount of field time last season, and Illinois should have a competition under center in spring practice. Both men will have to learn a new offense and show good decision-making skills after combining to throw 12 interceptions last fall.
• No Merci: All-American defensive end Whitney Mercilus is gone, and Illinois will be looking for his replacement this spring. The defensive line could once again be a strength for the Illini, especially with Gilmore back and an aggressive defensive coordinator in Tim Banks. It'll be interesting to see how the coaches use Michael Buchanan and Justin Staples, who played the "bandit" position in the previous scheme and boast speed but don't have typical defensive end size.

INDIANA

Start of spring practice: March 3
Spring game: April 14

What to watch:

• Juco fever: Indiana needs a quick fix on defense, and it hopes an influx of junior college players can provide one. Six juco players already are enrolled and will participate in spring practice, including five on the defensive side. It will be interesting to see how players such as defensive back Tregg Waters and linebackers Justin Rayside and Jacarri Alexander perform this spring as they compete to play right away.
• New direction on offense: Coach Kevin Wilson wants to be more productive in the passing game, and he hired an offensive coordinator in Seth Littrell who can help in that area. Littrell guided an Arizona offense that last season ranked third nationally in passing (370.8 ypg) and 27th in pass efficiency (145.2). He'll try to help Tre Roberson, who Wilson said he thinks can elevate his game significantly as a passer despite throwing twice as many interceptions (six) as touchdowns (three) as a freshman.
• Who has grown up: Indiana played 32 freshmen (16 true, 16 redshirt) in 2011, the most in the FBS. The early experience should pay off for several players, and Indiana needs them to grow up quickly during the spring. Roberson showed a lot of promise at quarterback, and safety Mark Murphy finished second on the team with 76 tackles. Keep an eye on players such as defensive end Bobby Richardson and receiver/returner Shane Wynn.

OHIO STATE

Start of spring practice: March 28
Spring game: April 21

What to watch:

• Urban renewal: The mood has improved around Ohio State's program from the moment Urban Meyer stepped to the podium Nov. 28. After putting together his staff, signing an elite recruiting class and ticking off some of his Big Ten coaching colleagues, Meyer finally gets a chance to work with the players on the practice field. After a lackluster final season at Florida in 2010, Meyer says he's refreshed and recharged, and it'll be interesting to see how he attacks practices.
• The new offense: Ohio State fans can't wait for a new offense after suffering through a 2011 season that featured some extremely questionable play-calling. Meyer's offensive system is well-known throughout college football, but the interesting thing this spring will be how Meyer and offensive coordinator Tom Herman blend their ideas. Herman is a dynamic young coach who impressed a lot of folks at Iowa State. But Ohio State is a different animal, and expectations will be high for quarterback Braxton Miller and the unit.
• Fickell back on defense: After spending last season as Ohio State's head coach, Luke Fickell returns to an assistant role on the defensive side. And for the first time, Fickell will be the Buckeyes' primary defensive playcaller. Ohio State's defense took a step back last season and will be looking to regain its traditional form. Fickell will work alongside co-defensive coordinator Everett Withers and look to identify some leaders to complement defensive lineman John Simon.

PENN STATE

Start of spring practice: March 26
Spring game: April 21

What to watch:

• O'Brien's time: Much will be made of Penn State opening spring ball without Joe Paterno, but the real story is how critical these practices will be for new coach Bill O'Brien and his team. Penn State will be acclimating to new systems on both sides of the ball and a new coaching style from O'Brien and his assistant coaches, all but two of whom are from the outside. The learning curve will be accelerated for all involved, as Penn State needs to get a lot done in 15 workouts.
• The quarterbacks: It's good that O'Brien has extensive experience coaching quarterbacks because no position needs a bigger upgrade at Penn State. The Lions struggled mightily under center last season and need a major boost beginning this spring. Can O'Brien get more out of Matthew McGloin and Rob Bolden, both of whom have seen extensive time in the Big Ten? How does Paul Jones factor into the mix? It'll be interesting to see how the signal-callers perform this spring.
• Filling gaps on defense: Penn State should have one of the nation's best linebacker groups this season, but the Lions need to fill some holes on the line and in the secondary. Big Ten Defensive Player of the Year Devon Still departs, and Penn State will be leaning on Jordan Hill and others to step up. A bigger concern is the secondary, which loses two multiyear starters at safety (Drew Astorino and Nick Sukay). Penn State also has a new defensive coordinator in Ted Roof, who will be looking for better results than he had at Auburn.

PURDUE

Start of spring practice: March 7
Spring game: April 14

What to watch:

• Another quarterback competition: Boilers coach Danny Hope loves having options at quarterback, and he'll once again get his wish during spring practice. Caleb TerBush, Robert Marve,Rob Henry and Sean Robinson all boast starting experience and will vie for the No. 1 job when workouts resume. Henry, who sizzled last spring and would have started the season if not for a torn ACL, has been cleared to participate in noncontact drills. Marve received an extra year of eligibility and will be in the mix. TerBush started every game last season.
• Tisebar takes over: Purdue has a new defensive coordinator for the third consecutive season, as Tim Tisebar takes over this spring. Tisebar returns to college football after spending the past three seasons with the Canadian Football League's Montreal Alouettes. Hope hired Tisebar to help Purdue improve against the spread offense and the zone-read game. It will be interesting to see what spin Tisebar puts on the defense as the Boilers enter a pivotal season.
• Offensive line depth: One of Purdue's strengths last season is a bit light on bodies following several departures. The Boilers need a left tackle to replace Dennis Kelly, and they also must increase depth on the interior line. Purdue already has moved tight end Robert Kugler to center, and Hope said earlier this month that several other tight ends could practice at offensive tackle during the spring.

WISCONSIN

Start of spring practice: March 17
Spring game: April 28

What to watch:

• A revamped staff: Bret Bielema hired six new assistant coaches during the winter months, including offensive coordinator Matt Canada. The new coaches will have their first opportunity to work with players on the field this spring. It's important for both sides to acclimate, mainly because Wisconsin has had tremendous success the past two seasons and doesn't want the staff shakeup to throw things off course. Quarterback Russell Wilson made a seamless transition to the program last summer. Let's see if the new assistants can do the same in spring ball.
• The quarterbacks: Speaking of Wilson, he departs Madison, leaving a major void under center. Jon Budmayr and Curt Phillips are coming off of major injuries, and while they're both making progress it could be tough to get a gauge on them this spring. Canada will spend much of his time working with Joel Stave and Joe Brennan, who need to get comfortable with Canada's adjustments to the offense and start establishing themselves as potential team leaders.
• Reloading up front: Wisconsin will have to replace two All-American offensive linemen for the second consecutive year, and the Badgers lose three All-Big Ten selections up front (Peter Konz, Kevin Zeitler and Josh Oglesby). While the Badgers are built to reload, offensive line coach Mike Markuson has a lot of evaluating to do this spring. On the defensive line, Wisconsin loses two starters (Patrick Butrym and Louis Nzegwu) and will be looking for some difference-makers. End David Gilbert returns to the mix after missing most of last season with a broken foot.

We covered all the offensive position groups in our postseason rankings series here, here, here and here. Now it's time to turn our attention to the defensive side of the ball.

Defensive tackle was the strongest position in the league in 2011, so that makes this a competitive situation. There are some major changes from our preseason order as well. Remember this is about overall production, and depth matters along with star power. The top four on this list are really, really strong.

Here we go:

1. Michigan State: The Spartans finished with the top total defense in the Big Ten and one of the best in the nation, and it all started with a dominant front. All-American tackle Jerel Worthy commanded extra attention inside and was joined by Kevin Pickelman and Anthony Rashad White as forces inside. William Gholston was brilliant at times, never more so than in the Outback Bowl win over Georgia. And freshman Marcus Rush turned in an outstanding season at the other defensive end spot. The Spartans had no weaknesses at this position in 2011.

2. Michigan: We projected the Wolverines would make a significant leap in '11, but the amount of improvement still surprised us. The combination of head coach Brady Hoke and defensive coordinator Greg Mattison, both defensive line coaches at heart, and valuable seniors Mike Martin and Ryan Van Bergen made this the backbone of Michigan's Sugar Bowl run. The Wolverines were especially tough in short-yardage situations because their defensive front was so stout.

3. Penn State: Big Ten defensive player of the year Devon Still wrecked just about everybody's game plan with a huge senior campaign. Jordan Hill had a solid, underrated year next to him inside. Jack Crawford stayed healthy and contributed 6.5 sacks, while Eric Latimore and Sean Stanley combined for another 7.5 quarterback takedowns.

4. Illinois: Defensive end Whitney Mercilus was a consensus first-team All-American who led the nation in sacks and forced fumbles. Nobody saw that coming. He had good company along the line as well, with guys like Akeem Spence inside and Michael Buchanan at the other end spot. The Illini may have faltered down the stretch as a team, but the D-line stayed strong throughout the year.

5. Wisconsin: The Badgers didn't have many household names on the defensive line, and certainly no one stood out like J.J. Watt the year before. But Bret Bielema relied on a solid group of veterans that helped the team finish third in the league in total defense and fifth in sacks. Patrick Butrym, Louis Nzegwu, Brendan Kelly and Ethan Hemer were part of a group that played better than the sum of its parts.

6. Ohio State: The Buckeyes had one of the best defensive players in the league in John Simon, who had 16 tackles for loss and seven sacks in a breakout season. Tackle Johnathan Hankins emerged as a disrupter at 335 pounds. But Ohio State didn't get its usual production elsewhere on the line, got beat up as the season went along and lacked depth, which is one reason why Urban Meyer went out and signed so many pass rushers in his first recruiting class.

7. Nebraska: The biggest disappointment from the preseason, as the Huskers tumbled from their No. 1 ranking last summer. Jared Crick's season-ending injury hurt the production, but he was not putting up huge numbers before he tore his pectoral muscle. Cameron Meredith, Baker Steinkuhler and Eric Martin had some nice moments, but Nebraska wasn't nearly as fierce up front as we thought it might be.

8. Purdue: Kawann Short turned in his best season, with 17 tackles for loss and 6.5 sacks from his interior spot, while Bruce Gaston and Gerald Gooden provided solid support. But the Boilermakers' pass rush off the edge lacked explosiveness until freshman Ryan Russell started to come on late in the season. Everyone except Gooden returns, and with a new position coach Purdue hopes this unit can go from decent to great in 2012.

9. Iowa: Another disappointing crew, as the Hawkeyes proved it's not easy to replace three draft picks off the defensive line and simply reload. Mike Daniels and Broderick Binns were the senior anchors, but Iowa's pass rush was sluggish until late in the season. And there wasn't a whole lot of depth behind them. This group loses three starters and will be extremely young in 2012.

10. Northwestern: We ranked the Wildcats 10th in the preseason as well, but we still expected better things out of this group. Northwestern generated very little pressure on opposing quarterbacks and ranked last in the Big Ten in sacks. Vince Browne, a projected all-conference pick in the summer, had a subpar season with only 3.5 tackles for loss after putting up 15.5 in 2010. It's clear this group needs to get better for Northwestern to take the next step.

11. Minnesota: The Gophers weren't as terrible on the defensive front as they were in 2010, when they finished last in the nation with only nine sacks. In fact, they more than doubled that total with 19 last season. Still, it was a mostly anonymous crew that gave quarterbacks too much time to carve up the secondary in the passing game. Jerry Kill still needs to find more playmakers at this position.

12. Indiana: The Hoosiers had problems all over the defense, and the line was no exception. Adam Replogle and Larry Black gave the unit some veteran leadership in the middle, but Indiana resorted to playing a lot of kids at the defensive end spots. The results were about what you'd expect.

The Big Ten recruiting classes are signed and sealed, and although a few more recruits could come aboard, we have a good idea of what the rosters will look like heading into the 2012 season.

That means it's Power Rankings time. Again.

We're taking a post-signing day look at where the league stacks up. There aren't too many changes from our previous rundown, but some teams received a bump from strong recruiting classes.

As they say on Twitter, #legooo.

1. Michigan State: The Spartans' recruiting class didn't crack ESPN's top 25, but it features several strong prospects and is loaded up at wide receiver and defensive back. Mark Dantonio tells us he can't remember recruiting 10 athletes like the ones Michigan State added in the class. Michigan State already is one of the Big Ten's most athletic teams, so this bodes well for the Spartans as they look for another big season.

2. Michigan: Brady Hoke and his staff rode a fast start to 2012 recruiting and finalized a class ranked No. 7 nationally. The Wolverines started three freshmen on defense in 2011 and added several more who can contribute early in their careers, including linebacker Joe Bolden, cornerback Terry Richardson and defensive tackle Ondre "Pee Wee" Pipkins. If Michigan can maintain its momentum on defense after losing several stud linemen, it will be very tough to beat in 2012.

3. Ohio State: Urban Meyer announced himself with a superb recruiting class featuring arguably the nation's best crop of defensive line prospects. Ohio State would have been an improved team in 2012 after its first seven-loss season since 1897, but the recruiting class boosts the Buckeyes even more. The defensive front seven should be a deeper and stronger unit, and players like Noah Spence, the Big Ten's top-rated recruit, have a chance to contribute immediately.

4. Nebraska: The Huskers missed on their top signing day target (offensive lineman Andrus Peat) but still inked a solid class that should help at positions like linebacker, where Big Red lacked size and depth. Linebacker Michael Rose could contribute early in his career. Nebraska also addressed the departure of standout cornerback Alfonzo Dennard with talented juco addition Mohammed Seisay.

5. Wisconsin: Quality not quantity was the theme for Wisconsin, which signed only 12 players, the Big Ten's smallest class by five recruits. The Badgers lost two offensive line commits to other schools but added a decorated quarterback in Bart Houston and some solid players to the defensive back seven, including linebacker Vince Biegel. This is the type of season that will test Wisconsin's ability to reload and provide a true gauge of the program's progress under Bret Bielema.

6. Penn State: New coach Bill O'Brien and his staff had to scramble to keep the class together, and the 2012 recruiting haul didn't quite match what Penn State adds in most seasons. The coaches were able to keep some good prospects and fulfilled a need at wide receiver with Eugene Lewis and others. It'll be interesting to see how quarterback Steven Bench turns out after Penn State lost verbal commit Skyler Mornhinweg to Florida.

7. Purdue: The Boilers added speed in their 2012 class, and they loaded up on quarterback prospects for the future with four signal-callers. But Purdue also beefed up along the offensive line with Jordan Roos and others. With coaching changes and personnel changes throughout the Leaders Division -- not to mention Ohio State's bowl ban -- Purdue has an excellent chance to make some noise in 2012.

8. Iowa: The big story in Iowa City isn't so much the recent recruiting class but the seismic changes going on in one of the nation's more stable programs. After having the same coordinators for the past 13 seasons, Kirk Ferentz must replace both Norm Parker and Ken O'Keefe, who left late last week for a post on the Miami Dolphins' staff. Iowa will have new leadership on both sides of the ball, creating some uncertainty but also some excitement. The Hawkeyes added some nice pieces in the 2012 class, such as running back Greg Garmon and defensive end Faith Ekakitie.

9. Northwestern: Although the Wildcats' class didn't crack the national rankings, it looks like the best haul in Pat Fitzgerald's tenure as head coach. Northwestern picked up a potential difference-maker on defense in defensive end/linebacker Ifeadi Odenigbo. Malin Jones could be the team's answer at running back, a spot that has suffered during Fitzgerald's tenure. The Wildcats also added the league's top transfer in former USC receiver Kyle Prater.

10. Illinois: It might take a year for Tim Beckman and his staff to make a big splash on the recruiting scene. Illinois' 2012 haul didn't receive great reviews, but the Illini are pursuing several nationally elite 2013 prospects from within the state. Linebacker recruits Tajarvis Fuller and Tyrone Neal should help Illinois in the defensive back seven. There's enough talent on the squad to get back to a decent bowl, but Beckman and his staff have plenty of work ahead.

11. Minnesota: The Gophers inked a class that drew good reviews from ESPN's analysts. Jerry Kill and his staff retained several top in-state prospects, including offensive lineman Isaac Hayes, wide receiver Andre McDonald and quarterback Philip Nelson. McDonald and fellow wideout Jamel Harbison could be immediate contributors for an offense that needs more options. But defense must be the top offseason focal point for Minnesota, which added several juco defenders.

12. Indiana: Although the Hoosiers remain at the bottom, we liked their recruiting class, which should first and foremost provide immediate help on defense. Junior college defenders like Tregg Waters and Jacarri Alexander likely will step in right away for a struggling unit. Indiana also will increase the competition at quarterback with heralded prep prospect Nate Sudfeld and juco addition Cameron Coffman.

National signing day is in the books, and it's time to evaluate the Big Ten teams and their classes. Although several potential Big Ten recruits are announcing their plans after signing day, most of the classes are complete.

Here's how ESPN Recruiting graded the Big Ten classes .

Let's take a look at how teams filled their big recruiting needs:

ILLINOIS

The Illini have had a nice run at defensive tackle with 2011 NFL first-round draft pick Corey Liuget and Akeem Spence, who enters 2012 as a legitimate pro prospect. They solidified the interior line for the future with recruits like Teko Powell and Vontrell Williams.

INDIANA

It's no secret Indiana needs to make significant upgrades on defense, and coach Kevin Wilson looked to the junior college ranks for help. Indiana added six juco defenders, including cornerback Tregg Waters and linebacker Jacarri Alexander. These players give the Hoosiers a chance to get better in a hurry.

IOWA

Running back has again become a pressing need for Iowa with the departures of Marcus Coker and Mika'il McCall. While Iowa has lost running backs at an alarming rate, it also has developed young backs very well in recent years. The coaches hope to work their magic with Greg Garmon, who could be the most significant recruit of the 2012 class.

MICHIGAN

Arguably no staff in the country makes defensive line a bigger priority than Michigan, which has three coaches, including head man Brady Hoke, focused on the front four. The Wolverines lose standouts Mike Martin and Ryan Van Bergen from the 2011 line, but they addressed the situation in recruiting with pickups like defensive tackle Ondre Pipkins and defensive end Chris Wormley.

MICHIGAN STATE

Michigan State is creating a nice recruiting pipeline at the wide receiver position. The Spartans lose their top two wideouts from 2011 (B.J. Cunningham and Keshawn Martin) but added several nice receiver pickups in the 2012, including Tennessee transfer DeAnthony Arnett and four-star prospects Monty Madaris and Aaron Burbridge.

MINNESOTA

Quarterback MarQueis Gray returns, and Minnesota needed to get him some help in the passing game after the departure of Da'Jon McKnight. The Gophers added some excellent pickups at the wide receiver position in Andre McDonald and Jamel Harbison.

NEBRASKA

The Huskers were thin at linebacker in 2011 and lose standout Lavonte David to graduation. Nebraska coaches also have discussed the need to add more traditional linebackers to face Big Ten offenses. Big Red filled the need in the 2012 recruiting classes with players such as Michael Rose and Jared Afalava.

NORTHWESTERN

Defense has been Northwestern's downfall in the past two years, and the Wildcats need more difference-makers on that side of the ball. They likely landed one in end/linebacker Ifeadi Odenigbo, an ESPNU 150 prospect who is Northwestern's most decorated defensive recruit in recent memory. Odenigbo could help immediately as a situational pass-rusher.

OHIO STATE

No Big Ten team made a bigger impact at one position than Ohio State did along the defensive line. The Buckeyes, who were a bit thin up front in 2011, got a lot better with this class, which is headlined by ESPNU 150 prospects Noah Spence, Adolphus Washington, Se'Von Pittman and Tommy Schutt.

PENN STATE

Skyler Mornhinweg's decommitment stings a bit, as Penn State needs more quarterbacks in the mix, but the Nittany Lions also need more difference-makers at wide receiver and tight end. They helped themselves in the 2012 class with wide receiver Eugene Lewis, ranked as the nation's No. 34 wideout by ESPN Recruiting. Tight end Jesse James is another nice pickup.

PURDUE

Offensive line has been a position of stability for Purdue the past few seasons, but the Boilers lose two starters from the 2011 squad (Dennis Kelly, Nick Mondek) and will say goodbye to several more after 2012. Purdue had to reload up front, and the two highest-rated players in the 2012 class, according to ESPN Recruiting -- Jordan Roos and Cameron Cermin -- all play offensive line.

WISCONSIN

Quarterback is undoubtedly Wisconsin's top priority as Russell Wilson departs and Jon Budmayr and Curt Phillips battle back from major injuries. The Badgers needed a signal-caller in a small class and landed a decorated one in Bart Houston, a four-star prospect from California powerhouse De La Salle High School.

National Signing Day is barely a week away, and Big Ten teams will be stockpiling for the future (and, in some cases, the present). Today we'll take a look at the recruiting needs of each Big Ten team, starting with those in the Leaders division. These needs are based on current rosters and anticipated departures in the near future. And to save you some email time, we do realize teams have already addressed needs in compiling their 2012 classes.

Let's get started ...

ILLINOIS

Wide receiver: The Illini lose A.J. Jenkins, who accounted for 90 of the team's 226 receptions in 2011. No other Illinois player had more than 26 catches, so there certainly are opportunities for young players to emerge and make an immediate impact for the new coaching staff.

Linemen: Illinois loses two starters from an offensive line that struggled down the stretch of the regular season. It's important to build depth there going forward. Despite Whitney Mercilus' early departure to the NFL draft, the defensive line returns some talented players. Still, defensive end Michael Buchanan is entering his senior year, and defensive tackle Akeem Spence is a bona fide NFL prospect who could enter the draft with a strong 2012 campaign.

Safety: The Illini defense didn't have many weaknesses in 2011, but safety was a liability at times. The team returns experience for 2012, but will lose some key players after the season. An impact defensive back or two in the 2012 class would really help.

INDIANA

Defensive back: This has been a primary recruiting need for the past few seasons, and it remains a pressing concern after Indiana surrendered a league-worst 8.5 yards per pass and a league-high 26 passing touchdowns in 2011. Indiana needs impact players and depth among the back four to be able to limit Big Ten offenses.

Defensive front seven: Sense a theme here? Indiana needs defenders in the worst way, and the front seven is a huge piece to the puzzle. The Hoosiers return some experience at defensive tackle, but lose top linebackers Jeff Thomas and Leon Beckum. The coaches showed in 2011 that they're not afraid to play young players, and they need more contributors on the defensive side.

Quarterback: Starter Tre Roberson returns, but Indiana needs bodies here after Dusty Kiel and Ed Wright-Baker both opted to transfer earlier this month.

OHIO STATE

Offensive line: Three multiyear starters depart at center, left tackle and right tackle, so Ohio State's offensive line will have a very different look in 2012. The Buckeyes could use some immediate-impact linemen, like center Mike Brewster in 2008, and they'll look to build depth here.

Defensive end: Ohio State appears loaded at defensive tackle for 2012 and beyond, but the team needs some more pure pass-rushers on the edge. John Simon, who had four more sacks than anyone on the squad in 2011, will be a senior this coming season.

Wide receiver: The Buckeyes lacked reliable receiver options in 2011 and had their best wideout, DeVier Posey, for only three games because of suspension. Posey departs and Ohio State needs to build depth and increase competition in what should be a more wide-open offense under Urban Meyer.

PENN STATE

Quarterback: New coach Bill O'Brien might be the quarterback whisperer Penn State has waited for, but he also needs to upgrade the talent on the roster. Matthew McGloin and Rob Bolden both must make significant strides, and while Paul Jones is an intriguing player, we've yet to see him in a game. Penn State needs more options here.

Wide receiver: Top target Derek Moye departs, and Penn State returns only two players with decent but not great production in Justin Brown and Devon Smith. Brown looks like a potential impact player in 2012, but Penn State needs more options in the passing game.

Defensive back: Penn State loses all four starters, although returning players like Stephon Morris, Malcolm Willis and Adrian Amos have logged playing time. Still, the Lions need some more players here to build depth and increase competition.

PURDUE

Offensive line: This is one of few areas where Purdue loses a decent amount of production from 2011, as tackle Dennis Kelly and Nick Mondek both depart. Two more starters exit after the 2012 season, and Purdue wants to be a run-based offense. It's important to build some depth up front with the 2012 class.

Kicker: Purdue loses the bionic-legged Carson Wiggs, who did more than make field goals from ridiculous distances. He also kicked off and served as a backup punter, attempting 45 punts over the past two seasons. The versatile Wiggs leaves a major void, and Purdue must address the specialist spot.

Defensive back: The Boilers say goodbye to both of their starting safeties from the 2011 team. They also will lose starting cornerback Josh Johnson after the 2012 season, while Ricardo Allen might be an early entry candidate with a big junior year. While this isn't a pressing need right now, it could soon become one.

WISCONSIN

Quarterback: Russell Wilson saved Wisconsin in more than one way in 2011, and his departure is significant. The team's most experienced signal callers, Jon Budmayr and Curt Phillips, both are coming off of major injuries. Wisconsin typically doesn't play younger quarterbacks, but needs more options after a season where Wilson showed what the offense could be.

Wide receiver: The Badgers typically get by with 1-2 good wideouts and an excellent tight end or two, but they could use more depth at the receiver position. Top target Nick Toon departs, and Wisconsin is pretty thin at receiver aside from Jared Abbrederis.

Defensive speed: Oregon makes a lot of teams look slow, but the Rose Bowl spelled out what the Badgers must do to take the next step as a program. Wisconsin needs to upgrade its speed at all three levels of the defense, particularly the back seven, to prevent explosion plays. Michigan State also exposed Wisconsin's defense, so the need for speed certainly is there.
