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.

During the course of spring practice, Big Ten bloggers Adam Rittenberg and Brian Bennett visited 11 of the 12 league schools, getting an up-close look at the players and coaches who will shape the 2012 season.

Now it's time for them to share their thoughts on what they saw and learned this spring, and you can follow along as they exchange emails. Check out the Leaders Division exchange here. They now turn their focus to the Legends Division.

Adam Rittenberg: Let's take a look at what I believe to be the stronger division in 2012. You spent a lot of time in the Mitten State last month, and while you didn't gorge yourself like you did in America's Dairyland, you got the money quote of spring ball from Michigan State coach Mark Dantonio, who said, "We're laying in the weeds. We've beat Michigan the last four years. So where's the threat?" How spicy is the Michigan State-Michigan rivalry getting, and how good do you think these two teams will be this season after visiting both campuses?

Brian Bennett: Oh, there was some serious gorging going on at Zingerman's in Ann Arbor and Sparty's in East Lansing. Good thing there's only one spring practice session per year.

Anyway, I went into the spring thinking Michigan and Michigan State were the two strongest teams in the league, and I didn't see anything to change my opinion. While the Wolverines are more focused on Ohio State and even Alabama, they know they have to end their losing streak against Michigan State. And the Spartans take serious pride in that four-game run while bristling at all the offseason accolades thrown toward Brady Hoke's team. Oct. 20 can't come soon enough, as far as I'm concerned.

If the two teams played right now, I'd definitely take Michigan State. Dantonio has done a terrific job of developing depth on both lines and all over the defense. There's not a deeper team in the Big Ten, and the Spartans' physical play has given Michigan fits. The Wolverines still need to figure some things out in the trenches, especially on the defensive line, but that's one area where Hoke and defensive coordinator Greg Mattison excel. I believe these two teams will be neck and neck all year for the Legends title.

Of course, there's another team lurking in the division, and that's Nebraska. You went to Lincoln this spring, and it sounded like the Cornhuskers are feeling mighty ambitious this season. Do they have the necessary tools to back up their lofty goals?

Adam Rittenberg: It was interesting to see a team openly discuss the national title, Brian, especially in a league like the Big Ten. Huskers safety P.J. Smith even went so far as to say a Big Ten title and a Rose Bowl championship would be "kind of disappointing." That's bold. Nebraska would have to skip a step or two to reach that point, but I can see where the confidence stems from. There's a greater comfort level between players and coaches in Lincoln, and also between the coaches and what they face in the Big Ten. Offensive coordinator Tim Beck was candid about the difficulty of preparing for so many new opponents, particularly since Nebraska's offensive and defensive systems are a little different from what we see in the rest of the league.

Quarterback Taylor Martinez received good marks from the coaches, and his focus on footwork could translate into a more consistent passing attack. Beck certainly wants to be a bit more balanced, and Nebraska returns pretty much everyone at wide receiver and tight end. We often hear the cliche that it's all about the quarterback, but it holds true with Nebraska. If Martinez actually makes strides as a passer -- he'll be operating in the same offense as the starter for the first time in his high school or college career -- the Huskers will put up points this fall. But after watching Martinez last season, it's fair to have some doubts about No. 3.

The defense expects to exploit a schematic advantage we heard a lot about last season but didn't see much on Saturdays. I like coordinator John Papuchis, and Bo Pelini made two good staff additions in D-line coach Rick Kaczenski and secondary coach Terry Joseph. They're all about details and accountability, and they believe they'll be able to replace star power with greater depth in certain areas. Nebraska also should be strong in special teams. Do the Huskers have a unit better than Michigan State's defense? Not right now. But Nebraska could end up being the division's most complete team by season's end.

Getting back to Michigan State and Michigan. Both teams lose tremendous leaders from 2011 (Kirk Cousins, Mike Martin, Jerel Worthy, Joel Foreman, David Molk, Ryan Van Bergen). Who do you see filling those roles this year?

Brian Bennett: That's a good question, and one that will have to be answered this summer. For Michigan State, Andrew Maxwell impressed me as a guy who can lead in a similar way as Cousins did; he'll just have to play well at quarterback and battle through adversity. The Spartans have some seniors on defense who can lead, like Anthony Rashad White and Johnny Adams, but they also have some highly respected juniors in Max Bullough and William Gholston.

But they are replacing some very valuable leaders, just as Michigan is doing. Denard Robinson has worked on becoming more vocal and sounded like a different guy in interviews this spring. There's no question he has the respect of his teammates. Craig Roh and Jordan Kovacs seem like natural leaders on defense, and offensive tackle Taylor Lewan says he wants to take on that role as well. But leadership can't be forced, and it remains to be seen if either team can find such strong captains as guys like Cousins and Martin were.

Speaking of question marks, I feel like Iowa and Northwestern are two of the bigger mystery teams in the league. Both have talent and potentially potent offenses, but they'll also need some players on defense to rise up out of the shadows. What did you take out of your visits to Iowa City and Evanston this spring?

Adam Rittenberg: Let's start off with Iowa, which underwent some major changes this spring with a new offensive coordinator (Greg Davis), a position coach promoted to defensive coordinator (Phil Parker) and several more assistants shuffling, arriving or being promoted. The players seemed to embrace the changes, and coach Kirk Ferentz basically said the team needed a fresh start even though he didn't want to lose his previous coordinators. There's a lot of excitement about Davis' offense, which will be more up-tempo than what we've seen in the past from Iowa. Quarterback James Vandenberg really seems to get it, but will he have enough weapons around him to execute? The running back curse struck again this spring with Jordan Canzeri's ACL injury. Iowa needs young and/or unproven players to step up there, and wide receiver isn't a deep group. It'll be a big summer for Keenan Davis.

The feeling I had coming out of Evanston is that Northwestern will be a younger team but potentially a better one. The Wildcats say goodbye to an accomplished senior class that featured some outstanding players like quarterback Dan Persa. But was it the most talented group? I don't think so. Northwestern has improved its recruiting efforts in recent years, and the team could begin seeing the benefits this year. There are a lot of new faces at spots like defensive back and defensive line. I was impressed with cornerback Nick VanHoose and end Deonte Gibson. The wide receiving corps should be one of the Big Ten's best, even if Kyle Prater isn't eligible until 2013. The Wildcats might not have many familiar names at receiver, but they boast incredible depth there. This team still has question marks -- secondary, pass rush, running back, quarterback -- but the talent level is getting a bit better.

Neither of us made it up to Minneapolis this spring, but we both talked with Gophers players and coaches. What was your sense of the second spring under coach Jerry Kill?

Brian Bennett: We swear it's nothing personal, Gophers fans. Both of us would have enjoyed a trip to the Twin Cities, but the schedule just didn't work out.

Anyway, I did sense more confidence from the Minnesota players and coaches we interviewed. That's not surprising, given that it's the second year for Kill's staff and more familiarity almost always brings a better comfort level. MarQueis Gray really started to come on late last season and appears to have made strides as a passer. He could be one of the league's top playmakers this year. Overall, the Gophers look to have a little more talent this year, thanks to some junior college imports, youngsters who got experience last year and Troy Stoudermire coming back at cornerback. The defense should have more speed, though it remains undersized. The big question for me is who will emerge as weapons alongside Gray, especially at receiver.

But I think that, with a manageable nonconference schedule, Minnesota has a chance to win five or more games this year and it will be much more competitive in Big Ten play than it was early last season. The Legends Division looks more balanced top to bottom than the Leaders and should be fun to follow all year.

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.

IOWA CITY, Iowa -- If you graded the magnitude of FBS coaching changes from the past offseason, Iowa's would barely make the needle move on the Richter scale.

Even in Big Ten territory, the ground shook more in places like State College, Columbus and Champaign. Iowa still has Kirk Ferentz, the new dean of Big Ten coaches, who has been at Iowa more than twice as long (13 seasons) as any of his peers in the league (Wisconsin's Bret Bielema and Northwestern's Pat Fitzgerald are next at six seasons each). Unlike Penn State and Ohio State, the program hasn't been mired in scandal, and none of the personnel moves were forced.

But in Hawkeye Country, the transformation of Ferentz's staff equates to The Big One.

Ferentz made the first two coordinator changes of his tenure, hiring former Texas assistant Greg Davis to oversee the offense and promoting secondary coach Phil Parker to lead the defense. Two assistants moved positions -- including Reese Morgan, who shifted from offensive line to defensive line -- and Ferentz hired two former players, Brian Ferentz and LeVar Woods, as position coaches.

In the quick-change environment of college football, such moves are typically greeted with a shrug. But Iowa has been the model of continuity. Before Davis, Ferentz hadn't made an outside coaching hire since naming Erik Campbell receivers/tight ends coach after the 2007 season. By keeping offensive coordinator Ken O'Keefe, defensive coordinator Norm Parker and strength coach Chris Doyle for the past 13 years, Iowa created what Ferentz calls "a great foundation of stability."

"We've had occasional changes here, but not like this," Ferentz told ESPN.com. "It was an interesting period."

It also has been an exciting one. Spring practice inherently brings a newness, as the slate is cleaned and planning accelerates for the upcoming season. But spring ball at Iowa has taken on a decidedly different tone, one Ferentz and his players are welcoming.

While Ferentz didn't force anyone out the door -- O'Keefe left for an assistant post with the Miami Dolphins, Parker retired and defensive line coach Rick Kaczenski left for Nebraska -- he vows that changes would have been made even if the staff had remained intact. Iowa has lost momentum following an 11-2 surge in 2009, its wins total dropping to eight during 2010 and to seven last fall.

"We just needed to go back and make sure everything made sense and was adding up the way we wanted it do," he said. "Just consider some new ideas, some things that might benefit our production. Now it's actually been forced by the [coaching] changes."

Asked how receptive he is to change, Ferentz, who some label as too conservative and set in his ways, replied, "wide open."

"Bottom line is we're 4-4 the last two years in conference play," he said. "If that's the best we can do, then that's fine. But we felt like we've left something out there."

The more seismic shift takes place on offense with Davis, who steps in after a year out of football. Although his 13-year tenure as Texas' offensive coordinator ended on a down note in 2010, his offenses averaged 39 points between 2000-09, the second highest total nationally and first among BCS automatic-qualifying teams.

Davis has had success with different schemes and different quarterbacks. While Iowa fans shouldn't expect a five-wide, spread attack this fall, a historically buttoned-up offense likely will loosen its collar a bit.

"I kept hearing from Kirk, 'Regardless of whether Ken had gone to Miami, we needed to do some things differently. We needed to make sure we're growing as a staff, as players, that we're taking advantage of what our kids can do,'" Davis told ESPN.com. "So meeting with the kids, meeting with the coaches, it's been very refreshing. They've been extremely open to everything. Sometimes the same play said differently and explained differently creates excitement.

"And I sense an excitement."

The feeling is mutual. Davis said last year was the first time he hadn't been part of a sports team since he was six years old.

The 60-year-old has returned to the field refreshed and revived.

"You can tell how much he loves the game," senior quarterback James Vandenberg said. "He gets really excited for practice, especially when we go against the defense. You'd think we were playing the Super Bowl with how excited he gets when we execute well. We show up early for lifting and he is literally here every morning at 6 a.m., always ready to go.

"We all kind of feed off of that."

Vandenberg enjoyed his time with O'Keefe and showed promise in his first season as the starter, passing for 3,022 yards with 25 touchdowns and seven interceptions. But after some struggles away from Kinnick Stadium and the team’s poor finish -- Iowa dropped three of its final four games -- Vandenberg also sensed a need for change.

"It's just new blood, which kind of re-energizes everybody,” he said. "It's making us work hard, and we're watching more film than we probably would in the spring. And it's making spring ball really competitive."

The changes on defense are more subtle. Phil Parker (no relation to Norm) said he"ll run "basically the same scheme" as his predecessor, sprinkling in some new ingredients and perhaps simplifying things for a group that is extremely young up front.

Parker is a new voice, though, and a powerful one.

"He's a go-getter," safety Micah Hyde said.

"I didn't think [the team] needed coaches leaving, that kind of change," Hyde continued, "but we haven't lived up to our expectations the last couple years. We definitely should have been playing better ball. It is a good thing, just to get some new input."

That a seven-win season equals disappointment in these parts resonates with Iowa players and coaches. Iowa hasn't had a losing regular season since 2000 and since 2001 has averaged 8.4 wins.

But Ferentz's critics point to his hefty salary, ranked in the top 10 nationally, and the fact that Iowa has had just one 10-win season since 2004. The team also needs to regain its mojo in close games, which have been the norm throughout Ferentz's tenure. After a terrific run from late in the 2008 season through most of the 2009 campaign, Iowa is 3-7 in games decided by seven points or fewer in the past two seasons.

"How we maximize those close situations usually determines how we end up," Ferentz said. "We haven't done a good enough job the last two years. Everybody would agree with that.

"That's documented, so what can we do?"

They've shaken things up. And just maybe they'll send shock waves through the Big Ten this fall.

IOWA CITY, Iowa -- Iowa running back Jordan Canzeri was scheduled to undergo knee surgery Wednesday, reducing an already thin position group from three to two.

"Hopefully, it will go well, and hopefully, he'll be cleared somewhere in the fall," Hawkeyes head coach Kirk Ferentz told ESPN.com. "But I don't think we can count on him next year. We're going to do what's best for him, first and foremost. We have to go on as if he weren't here."

Unfortunately for the Hawkeyes, it's a situation they know all too well. But it's also a situation they've handled remarkably well in recent years.

Despite having little to no proven depth at running back since 2008, the Hawkeyes have had a rusher finish in the nation's top 60 in each of the past three seasons.

It could happen again this fall. Damon Bullock and De'Andre Johnson both are drawing good reviews from Ferentz and new offensive coordinator Greg Davis through the first five spring practices.

"I'll probably jinx 'em," Davis told ESPN.com, "but they have not left the ball on the ground yet."

Iowa fans aren't too worried about that kind of jinx regarding the running backs. They'll be happy just having both Bullock and Johnson healthy and on the roster come September.

With heralded freshmen Greg Garmon and Barkley Hill joining the mix this summer, perhaps a featured back will emerge.

"We've had experience doing it for sure," Ferentz said. "We'll keep bringing those guys along, and when the new guys get here, we'll throw them in there as fast as we can."

Although Iowa wants to maintain its core beliefs of the power run and zone blocking, it's pretty clear the offense will trend more toward the pass under Davis. Senior quarterback James Vandenberg returns, and while All-Big Ten wideout Marvin McNutt departs, he'll have some weapons at wide receiver (Keenan Davis, Kevonte Martin-Manley) and tight end (C.J. Fiedorowicz, Zack Derby). The no-huddle will be a part of the scheme, and Iowa will try and stretch the field.

Like many, Vandenberg can't believe the misfortune that has plagued Iowa at running back, calling it "pretty crazy, actually." He also understands that the uncertainty in the backfield requires everyone else to elevate their play.

"Everybody realizes that we need to pick it up, as well as bring them along," he said. "You can't have 10 guys out there doing the right thing, and one guy doing something different because that messes it all up. So we're just making sure we're bringing them along and giving them confidence."

New offensive line coach Brian Ferentz has challenged his group to help make the running backs' job as easy as possible.

"We had an unfortunate injury with Jordan," said center James Ferentz, Brian's younger brother. "Brian just said no matter who's back there, it's our job to make sure there's holes and that we're making the way for that guy, whoever it is, to get 100 yards a game.

"Because if we can't do that, we're not going to win many games."

Iowa quarterback James Vandenberg has been brushing up on Greg Davis' history, both recent and ancient.

Since the Hawkeyes hired Davis as offensive coordinator, Vandenberg has watched numerous clips of former Texas quarterbacks Vince Young and Colt McCoy. Davis' last coaching stop took place in Austin, where he helped mold both Young and McCoy into elite college signal callers. As Vandenberg acclimates himself with Davis, he wants to get a sense of the system Davis has run and the quarterbacks he has coached.

But Vandenberg also is keenly aware he's not Young or McCoy. He's a different player with different skills. Will that be a problem for Davis? Hardly.

That's where the ancient history comes in.

"The one thing I always think of is he coached Gary Kubiak, who's the coach for the [Houston] Texans," Vandenberg told ESPN.com. "[Davis] was his college coach when [Davis] was only 28 years old. So he's been in the business for a long time and really knows the ins and outs and has done it with a lot of different people and systems."

Vandenberg is excited to be the next man in line. Before this offseason, Iowa hadn't made any coordinator changes -- offensive or defensive -- during head coach Kirk Ferentz's tenure.

While Vandenberg enjoyed working with former coordinator Ken O'Keefe, he echoes the seemingly program-wide excitement about having new voices in the football building and on the practice field this spring.

"It's some fresh blood," Vandenberg said. "That's what has everybody excited. There was nothing wrong with the old system, and we had a great coach. But the excitement comes with learning a new offense and hearing plays called from a new play-caller. There's a lot yet to be seen, but all these unknowns and knowing the success he's had is what has us all excited right now."

Davis' tenure at Texas ended on a down note in 2010, but his most recent success took place with McCoy and Young. The Longhorns had a top 25 offense every year between 2003-08. They led the FBS in scoring behind Young in 2005 en route to a national title and finished fifth in scoring behind McCoy in 2008.

Under Davis, Texas averaged 39 points per game between 2000-09, which ranked second nationally and first among teams from BCS automatic-qualifying leagues. While the numbers are notable, Davis' versatility has stood out to Vandenberg on tape.

"He knows how to play to his personnel," Vandenberg said. "When he had Ricky Williams there, he knew he was going to get 30 carries a game. When he had Vince Young, there was a lot of zone-read stuff. With Colt McCoy, there was a lot of empty stuff. He's adjusted to the guys he had and been successful in every aspect of offense, from power football to spread football.

"We're all excited to see what his wrinkle is for us."

Vandenberg, who racked up 3,022 pass yards with 25 touchdowns and seven interceptions in his first year as Iowa's starter in 2011, said he's familiar with most of the plays Davis wants to run, but needs to absorb new terminology and some different reads. Davis stresses the need to complete passes and get the ball out quickly, two areas Vandenberg feels are strengths of his.

Accuracy is a focal point this spring for Vandenberg, who completed just 58.7 percent of his attempts in 2011. His goal: 65 percent or better. He also wants to play smarter in games. To do so, he'll have to absorb Davis' system better than anyone else on the field.

"I'm able to bring guys along right now," he said. "I've had a little more time studying it. These practices are vital, just being to make sure we're all on the same page with all these new plays and all these new situations."

Change is in the air this spring at Iowa. The Hawkeyes have two new coordinators for the first time in Kirk Ferentz's tenure, one from the outside (OC Greg Davis) and one from within the program (DC Phil Parker). Ferentz also hired two new assistants, offensive line coach Brian Ferentz and linebackers coach LeVar Woods, and moved offensive line coach Reese Morgan to defensive line. For an Iowa staff built on continuity, this represents a a major shakeup. The coaches also will be working with a very young roster, as evidenced by the pre-spring depth chart issued this week. It all should make for an interesting spring in Hawkeye Country.

The Hawkeyes opened practice Wednesday, and ESPN.com caught up with Ferentz on Thursday.

Here are his thoughts.

What is the atmosphere like this spring being on the field with this group after all the changes?

Kirk Ferentz: Certainly we have a lot of learning to do for two reasons. Number one, our youth and inexperience, and secondly, with some of the staff changes. We have a lot of different elements involved. It's certainly different than when we finished up in December. It's a lot of positions, and some of it's schematically and that type of thing. We're all on edge a little bit, and that's good.

You made some of your hires fairly recently. How do you feel about where the offensive and defense schemes are at this point?

KF: We're pretty well down the road that we need to be on. We've had some really good meetings over the last several weeks. A little bit more intensive on the offensive side with Greg being hired at the end of February, but I think we've had good meetings. He certainly has a good grasp of what he likes to do and what he's comfortable with. We've been able to blend and mesh things. I think we're pretty much on the same page right now. It's been fun actually, just invigorating to re-examine some things. And the players, they always pick it up faster than the older guys.

When you sat down and talked with Greg, how close was your offensive philosophy to his?

KF: One of the things that really impressed me so much is his experience with various styles of offense. He's been with a lot of different types of players, quarterbacks, going back to Eric Zeier at Georgia, the guys he worked with at North Carolina, and at Texas, they ran several styles of attack. There was a lot of evolution when they got Vince Young. The thing is, he has a system that's been proficient and that he's comfortable with. It really is very flexible and adaptable. That part has all been good.

Very impressed with Greg, starting with all the recommendations I got, people who I have a lot of respect for in football who spoke so highly of him as a coach and so highly of him as a human being. And after a month of being with him, I can see why all of those things were said. He's really been tremendous. We've been fortunate to have great coaches here. You're always a little nervous when you lose somebody as good as Ken, but Greg has been outstanding.

I read your comments from the other day and wanted to clarify something. Did you expect to make some changes even if you didn't have the coordinators leaving?

KF: Absolutely. I was entertained a bit reading the reports of the press conference. The headlines were a little bit overstated. But that was something Ken and I had talked about, and Norm [Parker] and I had talked about as the year went on last year. You're 13 years into it, and we're all feeling good about being here such a long period of time. The great thing about stability is we all know each other.

But the other point, too, and every year you look back at things, but I remember specifically in Cleveland one year in '94 where we looked back and went through our playbook step by step. Steve Crosby had become our coordinator after the '93 season. We went through everything. The advantage of doing it is if you've been somewhere for a while, you add this one year and then you add that, and things don't always mesh or make as much sense as they should, so there's a cumulative effect there. So it's a good exercise to do, and I think it was time for us to do that regardless. And in the case of getting new coordinators, you have to do that anyway. It's been really healthy, it's been invigorating, and hopefully we'll be a more efficient operating group here moving forward.

You've talked about wanting to see better execution. What can you stress in the spring to help you execute better as a team?

KF: That's always the challenge in football. There were complaints about us. The perception is we're a conservative offense, and we threw the second-most amount of passes we had in 13 years last year, so I said they must have been conservative passes because we didn't get any credit for that. But overall, that's the name of the game, whatever you're doing, offensively, defensively or special teams, the key is how you execute those things. Certainly what you call can affect that, but at the end of the day, it's about the team that executes the best. That's the never-ending battle.

You have some guys out on the defensive line, but it's definitely one of the younger groups you've had there. With Reese Morgan moving over to that side, how do you see that group shaking out in the spring, and how will Reese's experience help there?

KF: It's maybe not identical, but it's similar to what we went through in 2005. We graduated four guys that were all in NFL camps after that season. Three of those guys are still active players -- Jonathan Babineaux, who's done a good job in Atlanta; Matt Roth's had a nice career; Derreck Robinson continues to be rostered; and Tyler Luebke is the other guy, was with the Redskins as a free agent. That's the price you pay when you graduate some good players. The last two years we've had a high number of seniors go out both years, and some NFL players in that group. It's something we anticipated, we knew it was going to be a challenge, but all that being said, we're optimistic.

One of my motivating factors for moving Reese over to that spot is Reese is just a tremendous teacher. That's the No. 1 thing I saw in him when we hired him here. He took Pat Flaherty's spot. He's a real builder, and he's done that with the offensive line. You look at last year, we had Riley Reiff, who people are talking about, but we also had Markus Zusevics and Adam Gettis, who both I think are going to get drafted here. They were both roughly 225, 230 [pounds] when they came out of high school and built themselves into players. Reese was a key component of their development, and that's what he does a great job of. I think we've got the right guy with the right group. We've got a lot of work to do, but at the end of the day, that group will be fine, just like in '05.

What would you like to see out of James [Vandenberg] during the spring?

KF: Just continued improvement. We expect him to play his best football next year and lead even better than he did. He played well last year and he led well, but he's going to have to do better. With a young team like this, it's going to be imperative that our most experienced guys play their best and lead our football team. It sure helps when you're playing better. And he's totally capable. We have confidence in James.

Is Keenan [Davis] another guy who fits into that category, needing to play his best as an older guy?

KF: Most definitely. If you look at the improvement Marvin McNutt made throughout his career, from making a move [from quarterback] in the middle of the '08 season, to the records he set, it didn't happen just by accident or just by him hanging around. He worked hard, he got better each year, and his hard work and effort, certainly in production and yardage, that's what we need from Keenan. Marvin's not here, quite obviously, so Keenan has to be the guy and take a very prominent role as a receiver. And he's certainly capable, so we expect to see that growth from him.

What would you like to see from the running back group by the end of the spring?

KF: Development and maturation. We have three guys that are working at that position who are talented enough. They're all capable, but they're young. Jordan Canzeri missed a significant amount of time last year with a hamstring issue. Damon Bullock, we moved him around enough that it probably rendered him ineffective. We'll let him settle at the running back position. And we think De'Andre Johnson has potential as well, but he's got to mature. He missed his first year because he was coming off an ACL injury from high school, so he's a little bit behind that way. But he's got every opportunity to develop and be a good player. It sure would help our football team.

When you're this young, are you more tempted to play freshmen if they come in and show that ability, or do you have to work with the guys who have some experience?

KF: We'll have a better grip on where we are at the end of spring practice. We're going to need some help at some spots, that's a given. Bottom line is for the most part, the guys that demonstrate they can play and help us, they're going to get that opportunity. We had the case with Allen Reisner. Back in '07, we had to throw him in. He was a true freshman. He wasn't necessarily ready to go, but we ran out of guys, so he had to go in there. We hopefully won't be in that situation. But anybody [who] can help us win next year, if it's special teams or on offense, defense, we'll give them an opportunity.

Greg came in from the outside, while Phil Parker has been there. What's it been like seeing him in this role? Do you see him putting his personality on the defense?

KF: We're early into the process right now. To the casual fan, it's not going to look a lot different, probably, but there will be some subtleties and some things not only Phil, but the entire staff talked about. It's like anything else, you're always trying to evolve and progress, move forward a little bit without losing your identity. That's probably what you'll see from that group. Phil's a veteran coach. He's had several chances to leave here for BCS coordinator positions and has chosen to stay here, so I don't think there's any question he's ready to go. He'll do a great job. He's very detailed and he's a good leader.

From a leadership standpoint, do you have some guys in mind, especially on defense, who you could see moving into those roles this spring?

KF: Most definitely. The guys that we're really counting on, you start with Micah Hyde. He's probably our most experienced player on defense, most proven, so we're counting on that from him. James Morris and Chris Kirksey, they're only third-year students next year, but they've played a lot of football, too, and good football. They're playing a leadership position at linebacker. And up front, I'd say Steve Bigach's a guy we're really counting on to really help set the tempo of the group. He's already been doing that, and I think he'll do a good job.

New Iowa offensive coordinator Greg Davis found himself in strange surroundings last year.

The veteran assistant coach did not have a job in football for the first time since 1973. Or, as he puts it, he wasn't part of a team for the first time since he was 6.

"It was surreal," he told ESPN.com. "The first Saturday of the season was different. It was the first one in a long, long time that I didn't wake up in the morning with my stomach turning."

Davis tried to keep up with football as much as possible. He visited with different college and high school teams in the spring and summer, and he taped every game he couldn't watch live during the season. On Mondays and Tuesdays, he'd tell his wife, Patsy, that he was going to work. Then he'd head upstairs and review the tapes while taking notes.

While Davis enjoyed spending time with his daughter and three grandchildren after moving to Dallas, he also missed the game. So when he heard Ken O'Keefe was leaving Iowa for a Miami Dolphins assistant job -- one that Davis also tried to land -- he sent Hawkeyes coach Kirk Ferentz a text message saying he'd love to come to Iowa City.

Ferentz hired a guy who coached some prolific offenses in 13 years at Texas, including an NCAA-record breaking attack in 2005 when the Longhorns won the BCS title and the 2009 team that played for the national championship. But Texas finished 88th nationally in scoring during a wildly disappointing 5-7 season in 2010, and Davis was forced out by his longtime boss, Mack Brown.

"Our talent level slipped a little bit, and we were just not as good," Davis said of that 2010 season. "We just didn't handle things as well as we had. That was really the only year out of 13 that I was there that I felt like we didn't do as good a job as we should have."

But Davis doesn't sound bitter over the loss of his job or the constant criticism he faced even while his teams piled up wins. He understands that's part of the deal. He tells the story of the time Texas Gov. Rick Perry, a Texas A&M graduate, attended Longhorns practice and told Davis he was happy to see Texas start drills. When Davis asked why, Perry said that it would take pressure off him.

"I grew up in Texas and adore their passion for football," Davis said. "I felt in most cases there was some justification [for the criticism]. We had set the bar extremely high with what we expect as coaches and players, and we didn't meet it."

Now Davis moves on to Iowa, where O'Keefe often faced intense scrutiny for his playcalling. Of course, coordinators are often merely an extension of the head coach, and Davis isn't about to reinvent Hawkeyes football. He said the system he installs will be a blend of what he knows and what Iowa has always done under Ferentz.

"I did not come up here to run Texas' offense," Davis said. "I came up here to run Iowa's offense. I'm sure we'll do some things differently and ask different things of the players. At the same time, they have done an outstanding job here."

Davis designs an offense based on what his players can do best. For example, he said he had never used a zone read play until Vince Young came along at quarterback in Austin. Option plays were cut out of the playbook when the less swift but super accurate Colt McCoy took over the job. When Davis first started at Texas, the Longhorns rode the running game behind Ricky Williams -- "You didn't have to be Bill Walsh to know you've got to hand it to the big boy," he says.

The trick now for Davis is figuring out the strengths of players he won't work with closely until the Hawkeyes start spring practice March 24. The playbook will evolve between now and the end of the spring game.

"We'll take the approach this spring that we're a little unsure of what exactly the guys can do, where the features should be," he said.

He has already watched all of Iowa's games from last season and likes what he sees in quarterback James Vandenberg. The rising senior threw for 3,022 yards and 25 touchdowns in his first year as a full-time starter in 2011. Davis has helped develop many outstanding quarterbacks over the years, including Eric Zeier at Georgia and Chris Simms and Major Applewhite at Texas before Young and McCoy. Davis thinks he has a lot to build on with Vandenberg from the film he's watched.

"I see a guy that can make all the throws, who's throwing it from one hash mark on the field to the other," he said. "That tells you right there that he has a good arm. I see a good decision-maker. I was pleasantly surprised that he is more athletic than I had first anticipated. He's making plays off schedule and gets the ball out of his hand quickly. I would anticipate him having a really good senior year for us."

The biggest issue might be locating a No. 1 running back. The departures of star back Marcus Coker and backup Mika'il McCall after off-the-field problems leaves Iowa with very little experience at tailback.

But Davis said that's a position where he's not afraid to play youngsters. Cedric Benson and Jamaal Charles were two players who saw immediate playing time as freshmen at Texas and turned out to be pretty good.

"You worry about protections, and you worry about the quarterback getting hit," he said. "By the same token, it's kind of our job as coaches to put them in situations they are ready for. Maybe they're not ready to be an every down back or play on third down against all the different blitzes. But if he's talented enough to get in and help us, then we need to be smart enough to make sure we can get him on the field and be productive."

Those are the kinds of coaching challenges that Davis is happy to be tackling once again.

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.

1. LSU fans still may be moping about the BCS Championship Game loss to Alabama. But the university’s decision to expand Tiger Stadium by nearly 7,000 seats is an indication of how successful the Tigers are. As the Baton Rouge Advocate reported, capacity at Death Valley will be a shade under 100,000. That moves LSU past Georgia and USC into seventh place in stadium size. The rich keep getting richer.

2. It makes sense that Kirk Ferentz, who had the same coordinators for all 13 seasons at Iowa, looked for a veteran assistant to run the offense. Greg Davis sat out of coaching in 2011 after parting ways with Mack Brown, for whom he worked at Texas and North Carolina. Hawkeyes fans accustomed to a potent running game may have to learn to love the quick pass into the flat. When Major Applewhite and Colt McCoy threw it, Davis always said it served the same purpose as a run.

3. If the Big East is so awful, and the Big 12 is so wonderful, how come it cost West Virginia $20 million to leave the former while Texas A&M and Missouri are paying “only” $12.4 million to leave the latter? It may be as simple as the Big East rule that called for West Virginia to remain in the league for two more seasons before it could extract itself. That doesn’t make it any less counterintuitive.

A vocal portion of the Iowa fan base longed to replace offensive coordinator Ken O'Keefe and bring in some new blood from outside the program. Those Hawkeyes fans got their wish but might be surprised at how similar the new playcaller is to the former one.

The 58-year-old O'Keefe resigned earlier this month after 13 years as Kirk Ferentz's offensive coordinator, moving on to an assistant's job with the Miami Dolphins. O'Keefe's conservative style was heavily criticized, though his offenses experienced major success behind star quarterbacks. Ferentz chose to replace him Monday with former Texas offensive coordinator Greg Davis -- a 60-year-old veteran assistant who spent 13 years calling plays for the Longhorns and who was criticized for being too conservative, though his offenses had major success behind star quarterbacks.

OK, it's far too simplistic to suggest O'Keefe and Davis are cut from the exact same cloth. But there are certainly some interesting parallels between the two.

Like O'Keefe, Davis probably weathered more criticism than he deserved. When he had it rolling, his offenses were some of the very best in the country. The 2005 Longhorns averaged more than 50 points per game on their way to the BCS title behind the singular talents of Vince Young at quarterback. He oversaw other prolific attacks led by quarterback Colt McCoy, as Texas beat Ohio State in 2009 Fiesta Bowl and earned a spot in the 2010 BCS title game. Davis also developed standout quarterbacks Major Applewhite and Chris Simms, not unlike how O'Keefe produced stars at the position like Brad Banks and Ricky Stanzi.

Yet for all of his successes in Austin, Davis never truly felt the love from the fan base. For the longest time, before Young blossomed into a superstar, the Longhorns stalled on offense against tough opponents, especially Oklahoma. After McCoy graduated, Texas struggled for two years to get back on track before Mack Brown finally showed his longtime trusted friend the door. The team struggled mightily to generate a strong rushing game once Jamaal Charles headed to the NFL after the 2007 season. To put it simply, Davis' offenses worked when he had a great quarterback and scuffled when they didn't.

While Texas used spread elements, particularly with Young and McCoy in charge, Davis often stuck to the basics and had a maddening tendency to play it safe in big spots. Sound familiar, Hawkeyes fans?

It must also be noted that Davis also benefited from some wildly impressive, blue-chip offensive talent that Brown recruited, like Young, McCoy, Charles, Roy Williams and Limas Sweed. While Iowa has done a great job under Ferentz of identifying and developing players, the Hawkeyes don't get the kind of five-star recruits that Texas brings in every year. Few teams do, so that's no knock on Iowa. Part of the problem in Texas the past couple years seems to be that the highly-rated recruits weren't as good as people thought. Can Davis succeed without top-notch talent?

Davis must also prove that he can design a consistent, competent running game, which has long been a hallmark of Ferentz's teams. He'll need to do so without any proven depth at the position after Marcus Coker's departure. The happiest man in Iowa City should be James Vandenberg, who should thrive under Davis in his second year of starting at quarterback.

Davis has been a coach for 33 years and has been a part of a lot of very successful teams. There is much to like about him and his résumé. There are also a lot of similarities between him and O'Keefe, for better and for worse. Ferentz has never had any other playcaller at Iowa besides O'Keefe, so it's little surprise that he stayed true to form with this pick.

We took a look earlier today at five players with the most to prove in the Big 12. Here are five more from the remaining Big 12 programs.

Darius Reynolds, WR, Iowa State

Reynolds was a highly-recruited juco prospect, but broke his leg after a strong start to the 2009 season and caught just 25 passes in 2010. This spring, coach Paul Rhoads went out of his way to note the improvement his 6-foot-3, 190-pound receiver made, and the Cyclones need him to prove Rhoads right. These receivers were the worst in the Big 12 in 2010, and they'll be breaking in a new quarterback in 2011. Can Reynolds prove he's a viable go-to receiver in this league?

Bryce Brown, RB and Arthur Brown, LB, Kansas State

There's no question about this one. This pair, despite not playing a down of Big 12 football yet, have attracted a ton of attention because of their accomplishments in high school back in Wichita and their modest careers at Miami (Arthur Brown) and Tennessee (Bryce Brown). But none of that matters now. Can these two prove they're more than just recruiting hype, and get Kansas State back in the postseason?

Landry Jones, QB, Oklahoma

Jones made big strides as a sophomore in 2010, both as a passer and a leader, but there's no getting past his struggles. He's prone to bad stretches and questionable decisions, and a fourth quarter at Missouri and the first half against Texas A&M cost Oklahoma two losses in 2010. If the Sooners are going to win the national title in 2011, Jones will have to be the guy to lead them there, and those kinds of lapses can't happen. Can he prove he's past them, and give the program its eighth national title and, perhaps, its sixth Heisman winner?

Garrett Gilbert, QB, Texas

I don't recall a player falling further short of his hype as Gilbert did in 2011. Place the blame (media, Gilbert, Greg Davis, Texas O-line, Alabama's second-half defense, etc.) where you'd like, but nobody thought he'd be a player who threw 10 touchdowns to 17 interceptions in his first year as a starter. Now, he finds himself in a quarterback competition that might end with him on the bench. Can he prove he's the top-flight quarterback Texas recruited, or will he lose his job to a younger teammate?

Alex Torres, WR, Texas Tech

Torres had a huge freshman year (67 catches, 806 yards, 6 TD), but injuries kept him from getting going at the same rate as a sophomore in 2011, when he finished with just 39 catches for 481 yards and three scores. The Red Raiders top two receivers are gone now, though, and they'll be breaking in a new quarterback, Seth Doege. For Torres, now is the time. Can he prove he's capable of keeping the Texas Tech offense humming at the same rate it's done for the past decade and longer?

Spring football is in full swing. Three teams from the Big 12 (Texas Tech, Baylor, Texas) are already done, and the last team in the Big 12 to start (Kansas State) kicked off on Wednesday.

That leaves seven teams in the Big 12 on the field, but who's coaching them? We've had plenty of teams shift coordinators this season, so here's a quick refresher if you've been busy following basketball since the season ended and the coaching carousel began spinning.

BAYLOR

Defensive coordinator: Phil Bennett. He replaces Brian Norwood, who moved to associate head coach and secondary coach. Bennett was previously the defensive coordinator at Pittsburgh, where he coordinated the nation's No. 8 defense.

KANSAS

Offensive coordinator: David Beaty. He spent a year at Rice, but returned to Kansas to coach receivers and serve as co-offensive coordinator alongside Chuck Long. He replaces Darrell Wyatt, who left to coach receivers at Texas. Long retained play-calling duties.

OKLAHOMA

Offensive coordinator: Josh Heupel and Jay Norvell. They'll share offensive coordinator duties, with Heupel calling the plays. He did so during the Sooners' 48-20 win over Connecticut in the Fiesta Bowl. They'll replace Kevin Wilson, who left to become the head coach at Indiana. Heupel will continue to coach quarterbacks as he has since 2006. Norvell will continue to coach receivers as he has since 2008.

OKLAHOMA STATE

Offensive coordinator: Todd Monken. He'll replace Dana Holgorsen, who took over as offensive coordinator at West Virginia and is scheduled to replace Bill Stewart as the head coach in 2012. Monken previously coached receivers for the Jacksonville Jaguars.

TEXAS

Offensive coordinator: Bryan Harsin. He spent a decade at Boise State and five years as offensive coordinator, and will replace Greg Davis, the longtime coordinator under Mack Brown who resigned after the 2010 season.

Defensive coordinator: Manny Diaz. Another young coach, Diaz was at Middle Tennessee State in 2009 and coordinated the defense at Mississippi State under Dan Mullen last season. He replaces Will Muschamp, who left to become head coach at Florida.

TEXAS TECH

Defensive coordinator: Chad Glasgow. Previously the secondary coach at TCU, Glasgow helped the Horned Frogs win the Rose Bowl last year and parlayed his recent excellence into a coordinator gig in Lubbock, where he'll replace James Willis, who left the program in December, before the Red Raiders beat Northwestern in the inaugural TicketCity Bowl.

LOS ANGELES -- Informed Tuesday that he's a finalist for Texas' offensive coordinator vacancy, Wisconsin OC Paul Chryst smiled and laughed.

This was news to him.

"There really is a lot more buzz than actual [truth]," Chryst said. "It's pretty nice right now to just hone in on our business."

Chryst, who oversees one of the nation's top offenses in Madison, had been mentioned as a candidate to succeed Greg Davis with the Longhorns. The 45-year-old is in his sixth season as offensive coordinator at Wisconsin, where he played in the 1980s and served as tight ends coach in 2002.

Chryst is the Big Ten's second highest-paid assistant (total compensation: $361,094, maximum bonus: $122,500) behind Illinois offensive coordinator Paul Petrino. Chryst likely will receive a healthy raise after the season if he chooses to stay, although Texas has deep pockets, paying Davis $477,084 this season (maximum bonus of $56,393).

"I'm pretty lucky," Chryst said. "Wisconsin isn't unique to this, but the players are fun to be around. We're not always having laughs and giggles, but I appreciate [them] a ton. They work, they want to be good. They're willing to do what you ask.

"I work with a group of guys on the offensive side of the ball that I truly enjoy being around and are really good football coaches. I appreciate what Bret [Bielema] has done and allowed us to do."

Money certainly talks, but I'd be surprised if Chryst leaves Wisconsin, where he and his family are very comfortable. He wants to be a head coach and interviewed with Minnesota for its vacancy, but until he lands a top job, he'll likely remain at Wisconsin or look to the NFL.
