Iowa has little trouble producing quality running backs. Keeping them on the team is an entirely different story.

Marcus Coker on Tuesday became the latest promising Iowa ball-carrier to depart the program. The team announced Coker asked for a release from his scholarship, which was granted. The sophomore also didn't enroll for the spring semester at Iowa.

Of all the Hawkeyes' running back departures -- Adam Robinson, Brandon Wegher, Jewel Hampton, Mika'il McCall -- Coker's is the most mysterious and potentially the most damaging. Head coach Kirk Ferentz still hasn't specified why Coker was suspended for the Insight Bowl -- the team called it a violation of university policy and the student-athlete code of conduct. While McCall seemed likely to return after his suspension, Coker's situation seemed different. Athletic director Gary Barta said last month that Coker had an invitation to return to the team.

But it didn't pan out and Iowa once again will be scrambling at running back heading into the 2012 season.

Coker isn't just good -- he finished second in the Big Ten and 15th nationally in rushing average (115.3 ypg) -- but he's also durable and productive, logging 23.4 carries per game, tops among Big Ten backs. As a big back with two more years to mature, Coker could have been a special player at Iowa.

The Hawkeyes will tun to Jordan Canzeri, who provided a nice spark at times in the Insight Bowl, and others at running back in the 2012 season. But Ferentz and his staff need to address what has become a revolving-door position. Why are so many promising running backs on the field struggling so much off of it? The team now has had five running backs depart in the past year and a half.

Not good at all.

"I wish I could explain it," Ferentz told me last month. "There's no conspiracy theory or anything like that. We've just had some situations. You have to evaluate each one on an individual basis. We have had our share of transactions and transition. We'll get it settled down again."

They had better.

Iowa is no stranger to facing adversity in a bowl game.

In the 2001 Alamo Bowl, the Hawkeyes' first postseason appearance under head coach Kirk Ferentz, running back Ladell Betts couldn't play with a hamstring injury, leaving Iowa without a four-year starter. Iowa turned to Aaron Greving, who racked up 115 rush yards and earned offensive MVP honors in a win against Texas Tech.

The Betts-Greving situation hardly compared to the crisis Iowa faced before the 2010 Insight Bowl. Top running back Adam Robinson had been suspended and subsequently arrested. Top receiver Derrell Johnson-Koulianos had been arrested on drug charges, leading to an odd news conference where Iowa admitted to finding problems with its drug-testing program for student-athletes. The team also announced that two reserve running backs, Jewel Hampton and Brandon Wegher, were transferring.

And yet Iowa still won the game, rallying to upset Missouri 27-24.

Another Insight Bowl matchup is on tap Friday night against Oklahoma, and Iowa once again is dealing with some adversity. Sophomore running back Marcus Coker, the team's most productive offensive weapon, is suspended for an undisclosed violation of team policy. There are other potential personnel issues, which Ferentz deflected Tuesday, but replacing Coker's 281 carries and 1,354 rush yards is the big one.

"It's football," Ferentz told ESPN.com on Tuesday. "If our running back had sprained his ankle, he wouldn't play then, either. So you don't surrender and forfeit the game. You keep playing. It happens all year long. Players are in and out. Somebody has to be ready to step in, and everybody else has to help those guys out."

Coker was that guy for Iowa last December, rushing for a team-bowl record 219 yards and two touchdowns against Missouri. But his loss leaves the Hawkeyes with a stable of unproven backs.

Ferentz said Jason White, who he describes as "steady" and "dependable," and Brad Rogers, who has mostly played fullback for Iowa, likely will be the team's top two ball-carrying options Friday against Oklahoma. Freshmen Jordan Canzeri and Damon Bullock are the next two in line.

"We'll basically use everybody we have," Ferentz said. "I don't know if I foresee us getting 200 yards like a year ago, and if we did, it will probably be three, four, five guys contributing to that yardage, not one. We'll do it by committee and just see how it goes."

Iowa's passing attack has been very effective at times, especially early in the season when the Hawkeyes employed some no-huddle. Oklahoma ranks just 83rd nationally against the pass.

But the Hawkeyes won't abandon their run game Friday night. Because they can't.

"We have to at least attempt it," Ferentz said. "We're not built to throw it 70 times a game. It's just not our mode of operation. If we get in a situation like that, it's not good. But the group's capable. They've been practicing well and they'll step up and do a good job."

The suspensions of both Coker and freshman Mika'il McCall have once again placed the spotlight on Iowa's running back position, which has seen an extraordinary amount of turmoil since the departure of Doak Walker Award winner Shonn Greene after the 2008 season. Five promising backs have dealt with off-field issues since Greene's departure.

"I wish I could explain it," Ferentz said. "There's no conspiracy theory or anything like that. We've just had some situations. You have to evaluate each one on an individual basis. We have had our share of transactions and transition. We'll get it settled down again."

When bowl games kick off, Iowa usually finds a way.

In 2008, Iowa caught a big break at the running back position when Shonn Greene went from furniture warehouse employee to Doak Walker Award winner.

Since then, the Hawkeyes haven't had much good fortune with their running backs. Whether it's injuries or off-field problems, Iowa's running back depth has taken hit after hit since Greene's magical season.

The latest blow came Tuesday as the team announced starting running back Marcus Coker has been suspended for the Insight Bowl for disciplinary reasons. Iowa didn't elaborate on the suspension, saying only that Coker violated the school's student-athlete code of conduct. The sophomore will not travel with the team to Arizona later this week.

It marks the second consecutive year Iowa will play the Insight Bowl without its top back. Adam Robinson was suspended for the game last year for failing to comply with team policies. Iowa announced Robinson's suspension on the same day it confirmed running back Jewel Hampton, the team's second-leading rusher in 2008, would be transferring. Hampton dealt with injuries and off-field issues. Another promising running back, Brandon Wegher, announced late last season that he would also be transferring (he took a leave of absence from the team in August 2010). Weeks after Iowa announced Robinson's suspension, Robinson was arrested for marijuana possession.

Coker ended up rescuing Iowa in the 2010 Insight Bowl, rushing for a team bowl record 219 yards and two touchdowns in a win against Missouri.

He has been a huge part of Iowa's offense this season, accounting for 80.7 percent of the team's rushing yards (1,384), 15 of the team's 18 rush touchdowns and 281 of the team's 417 carries. Coker leads the Big Ten in carries and ranks second in rushing average (115.3 ypg).

Who will Iowa turn to at running back? Promising freshman Mika'il McCall was suspended for the regular-season finale against Nebraska, and his status for the bowl game is very much in doubt.

Iowa likely will turn to DeAndre Johnson, Jordan Canzeri, Damon Bullock and Jason White at running back. Johnson leads the crew with just 18 carries this season.

Gulp.

It's hard not to see Iowa becoming pretty one-dimensional against Oklahoma. The good news is the Sooners struggle against the pass, ranking 83rd nationally.

The bigger issue is why Iowa can't keep running backs on the field. The Hawkeyes seem to have little trouble developing running backs, but the lack of depth has become a major problem.

Marcus Coker envisioned following in Shonn Greene's footsteps when he signed on to play running back at Iowa. Another type of star system also led him to the Hawkeyes.

Since his mother bought him a telescope at age 7, Coker has been fascinated by the stars in the sky. One of the reasons he chose Iowa out of DeMatha Catholic High School in Maryland, he said, was the school's department of physics and astronomy. Coker is pursuing a double major in both fields and says his dream is to some day work for NASA.

A Hawkeye in space?

"Nah," he says. "I want to stay on the ground."

That looks like a pretty good plan for Iowa this season as well, thanks to the promising sophomore tailback. Coker might have been eclipsed at the beginning of last season, but by the end he looked like a supernova.

His jaw-dropping Insight Bowl performance has fans salivating at his future potential. Stepping in for the suspended Adam Robinson, Coker shattered school bowl records with 219 rushing yards on 33 attempts in the 27-24 win over Missouri.

Coker didn't even figure to crack the depth chart initially as a freshman, with fellow backs Robinson, Jewel Hampton and Brandon Wegher all ahead of him. Coker was further set back by a broken collarbone in preseason camp.

"There was no way to get physical reps after that, so I just tried to get mental reps and more than anything learn the offense," he said. "I really didn't think I would play much. That was my goal, but I didn't have any expectations."

But then Hampton and Wegher transferred, and Robinson was sidelined by both academic and legal issues. Coker was playing a big role by the end of the season, rushing for 129 yards against Indiana and scoring his first touchdown versus Ohio State. With Robinson gone and little experience behind him, Coker is the unquestioned leader in the backfield now. He's trying to keep the same attitude he had last summer.

"I look at myself as if I'm last on the depth chart, and I want to be first," he said. "[The bowl] game just brings a lot of expectations, so I'm trying to push myself hard and live up to all those expectations."

Expectations may be unreasonably high after a 219-yard bowl performance, but Coker says, "All I know is I'm going to go out and try to rush for more than that every game. If it happens, it happens."

He's not unfamiliar with huge games. In high school, he gained national attention by rushing for a school record 392 yards and five touchdowns to lead DeMatha to a victory over rival Gilman.

Coker is a load at 6-foot, 230 pounds. He said he's been working this offseason on improving his quickness and agility, but he knows the most important thing is to keep his pads low.

"When you have that much weight behind you, it's kind of hard not to run over some corners and safeties," he said.

There's a softer side to him too, though. Coker was recognized in high school for performing more than 1,000 community-service hours, donating his time to working with the mentally challenged and volunteering at animal shelters.

"I get that from my mom," he said. "She has worked with mentally challenged people since I was born. She's always giving to other people, and I want to give back."

That's the kind of attitude that could make Marcus Coker a true star.

Springtime is almost here. And here's a look at what to expect across the Big 12 when it gets into full swing here in the next couple weeks.

BAYLOR BEARS

Spring practice starts: February 28

Spring game: April 2

What to watch:

• Big changes on defense. Baylor brought in Phil Bennett as its new defensive coordinator, and he says his scheme will be multiple, built to fit the Bears' personnel. Considering the Bears' recent recruiting successes in the secondary, look for a 4-2-5 type of look.
• Recruiting stars: time to shine. Both safeties, Tim Atchison and Byron Landor, are gone. Baylor, though, has two former ESPNU 150 recruits at safety who would be well served to start filling their potential. Prince Kent was a reserve last season and at one time, the nation's No. 51 overall recruit who originally signed with Miami. Ahmad Dixon, meanwhile, was the No. 15 overall prospect in the 2010 class. The opportunity is there. Baylor needs big talent at the position. Briles has recruited it. Can they develop into players who make Baylor a contender?
• Running back competition. Jay Finley topped 1,200 yards in 2010, but he's gone. Who steps into his void? Terrance Ganaway is a bowling ball at 5-foot-11, 235 pounds, but the shifty Jarred Salubi could get a good amount of carries, too. They could begin to share carries this spring.

IOWA STATE CYCLONES

Spring practice starts: March 22

Spring game: April 16

What to watch:

• Quarterback competition. It should be a good one in Ames this spring. Jerome Tiller is the name most recognize after getting lots of meaningful time and starts because of injuries to Austen Arnaud over the past two seasons. But juco transfer Steele Jantz sounds confident he can win the job. Rising sophomore James Capello and redshirt freshman Jared Barnett will compete, too.
• Paging Cyclone receivers. Iowa State had one of the most underwhelming receiving corps in the league during the past season, and three of its top five pass-catchers won't return in 2011. Of those three, however, one is a tight end (Collin Franklin) and another is a running back (Alexander Robinson). The new quarterback will need some help, and Darius Darks and Darius Reynolds will need to provide it as seniors.
• Shontrelle's time or not? Freshman Shontrelle Johnson looked like the running back with the most pop behind Robinson for most of 2010, but two other freshmen running backs jockeyed for carries, too. Paul Rhoads is hardly handing the job over to Johnson, but spring could be the time when he really separates himself from the pack.

KANSAS JAYHAWKS

Spring practice starts: April 1

Spring game: April 30

What to watch:

• What are they doing behind center? Kansas never got much consistent play out of the quarterback position last year, but freshman Brock Berglund is one of the 2011 class' top recruits, and enrolled early to compete in the spring with Jordan Webb and Quinn Mecham. With a building program like Kansas, there's perhaps some value in handing the program to a younger player like Webb or Berglund, but they'll have to earn it. Doing so will start in the spring, but don't expect the Jayhawks to have a set-in-stone starter by spring's end.
• Top linebacker back on the field. Huldon Tharp missed all of 2010 with a foot injury, but he says he's 100 percent and ready to get back on the field. As a freshman in 2009, he was fifth on the team in tackles, with 59, and looked like one of the league's possible budding stars. Now, he'll get his chance to join fellow linebacker Steven Johnson as one of the team's top tacklers, and he'll do it as a sophomore after redshirting in 2010.
• Toben rising? Turner Gill raised plenty of eyebrows when he moved his team's leading rusher in 2009, Toben Opurum, to linebacker in fall camp, and eventually slid him up to defensive end. But toward the end of 2010, Opurum started showing some major signs of growth at the position. We'll get a better idea this spring if he's one of the league's most unlikely new stars at defensive end.

KANSAS STATE WILDCATS

Spring practice starts: April 6

Spring game: April 30

What to watch:

• Prodigal Kansan sons come home. There's no doubt that the Wichita native Brown brothers are the main attraction at Kansas State this spring, a season after transferring back home. Bryce Brown, the running back, was the nation's No. 8 prospect in the 2009 class. Arthur Brown, the linebacker, was the nation's No. 6 prospect in the 2008 class. Bryce transferred from Tennessee and Arthur from Miami. The Wildcats are pinning much of their hopes on the duo, and we'll get a good sense of what they can provide soon.
• Quarterback competition. Carson Coffman is gone, and two new faces will challenge for the job: juco transfer Justin Tuggle and Daniel Sams. Sammuel Lamur is also up for the gig. Collin Klein may or may not be; Bill Snyder hasn't explicitly confirmed a past comment from Sams saying Klein had moved to receiver. Don't expect a starter to be named by spring's end, but a general order could start to form.
• Can the defense show improvement? Kansas State had the Big 12's worst overall defense last year, and the worst rushing defense in college football, giving up 3,008 yards on the ground. Coordinator Chris Cosh looks like he'll still be around in 2011, and defensive backs David Garrett and Tysyn Hartman are solid pieces to try and build around. But this young maturing defense must get better to make a bowl game again with so many questions on offense. That starts in the spring.

MISSOURI TIGERS

Spring practice starts: March 8

Spring game: April 16

What to watch:

• Franklin comes alive! Blaine Gabbert bolted to the NFL early, and Missouri has a gaping hole a quarterback. The position, however, is surrounded by a lot of quality talent that likely makes the Tigers a Top 25 team. There's no understating the importance of the position for the Tigers, and that will begin to be decided in the spring. James Franklin, a rising sophomore, saw spot duty in 2010 as more of a runner, and may have the inside track on the job, but Tyler Gabbert, Blaine's younger brother, and Ashton Glaser should make it an interesting competition in the spring. If neither of them impress early, don't count out incoming freshman Corbin Berkstresser.
• Here is the new secondary. Same as the old secondary? After years of pass defense being one of the Tigers' biggest weaknesses, it became a strength in 2010 behind the leadership of senior corners Kevin Rutland and Carl Gettis. But the Tigers lose them and safety Jarrell Harrison. Rutland emerged as one of the team's most impressive players last spring, but was Missouri's success in the secondary a one-time thing or the beginning of a welcome trend?
• Time to dominate the trenches? Missouri played without likely first-round pick Aldon Smith for much of the previous season, but the defensive and offensive lines for the Tigers were as good as ever in 2010. How will they look in 2011? Impact juco transfer Sheldon Richardson won't be enrolled by the spring, but the four returning starters on the offensive line should get some solid work against Brad Madison, Jacquies Smith and Terrell Resonno.

OKLAHOMA SOONERS

Spring practice starts: March 21

Spring game: April 16

What to watch:

• Freshmen on display. Coach Bob Stoops hasn't been shy about saying his 2010 recruiting class was his best ever, but it could look even better after this spring. Two of his best emerging recruits, Justin McCay and Geneo Grissom, didn't even play in 2010, and could start to make an impact. The same goes for Corey Nelson, who will try to earn some more time somewhere backing up star Travis Lewis.
• Is there a golden boot in Norman? Jimmy Stevens was much more accurate in 2010, finishing 19-for-23, but his attempts outside 45 yards were sparse. The good news is he missed none of his 53 extra points. Field goals have been a bit of an adventure for the past couple years, but continuing in the spring what he started last year would be a good sign for Oklahoma. The Sooners are strong everywhere and need good special teams play to reach their lofty title goals.
• Are the Sooners' backs back? Roy Finch missed the Fiesta Bowl with a stress fracture, and his durability is certainly questionable entering 2011. When he's healthy, he looks like the next star in the Sooners' backfield, but they'll need some depth behind the 5-foot-8, 173-pounder. Jermie Calhoun, Jonathan Miller and Brennan Clay have all looked good at times, but there should be some good competition from newcomers Brandon Wegher, an Iowa transfer who'll be in camp this spring and eligible next season, and blue-chip recruit Brandon Williams, who enrolled early.

OKLAHOMA STATE COWBOYS

Spring practice starts: March 7

Spring game: April 16

What to watch:

• Every piece of the offense. The spring in Stillwater is all about keeping or improving upon the status quo. Had it kept Dana Holgorsen, there'd be little doubt that would happen, but Oklahoma State must make the most of its five returning offensive linemen, quarterback Brandon Weeden and receiver Justin Blackmon. The opportunity for a historic season is there, but they'll have to pick up the nuances of the new offense quickly in the spring like they did last year.
• What about the kicker? Dan Bailey won the Lou Groza Award as the nation's top kicker in 2010, but he's gone. Oklahoma State needs to fill that role quickly, and we'll likely know who will get the nod after the spring.
• Who steps up on the defensive line? The Cowboys lose three starters up front on defense, including All-Big 12 performer Ugo Chinasa and tackles Chris Donaldson and Shane Jarka. Can senior Richetti Jones become a star in the Big 12? We'll have a good idea if he, or any of the Cowboys' other defensive linemen, can by the end of April.

TEXAS LONGHORNS

Spring practice starts: February 24

Spring game: April 3

What to watch:

• New coaches and their students/players. Texas has five new coaches. Although it's hard to get a good read early on, how they relate with the players on the field, in the film room and around the facilities will have a big impact on how the 2011 season plays out in Austin. The young-blooded coordinators could serve themselves well by relating to players and the players will need to spend plenty of extra time learning new schemes and plays.
• Quarterback competition ... or not? Mack Brown says the gig is open and it is, for now. Garrett Gilbert can close it with a strong spring. If Garrett struggles on the field or has difficulty grasping the new system, the door will be wide open for Connor Wood or Case McCoy to step in and close it. Gilbert didn't get much help, but he did very little in 2010 to inspire a lot of breathing room with McCoy and Wood clamoring for playing time.
• And you've got to defend the pass, too. Texas loses its top three cornerbacks to the NFL, and only Carrington Byndom and A.J. White got much meaningful playing time last season. Younger players can earn some rare early playing time with a strong spring. Will anyone step up?

TEXAS A&M AGGIES

Spring practice starts: March 22

Spring game: April 16

What to watch:

• New linebackers in the running. Spring isn't so scary when you bring back nine defensive starters, but the two Texas A&M lost were the heart of its defense. Linebackers Michael Hodges and Von Miller are gone. Kyle Mangan didn't look fantastic when forced into action during the Cotton Bowl, but the time is now for Damontre Moore and Dominique Patterson, a pair of sophomores, to make their impact.
• Tannehill's tuning things up. Quarterback Ryan Tannehill played about as well as anyone could have hoped late last season, but he'll need it to continue his performance with a solid spring nailing down the timing with his receivers, who all return. He's already got a leg up on last year's quarterback, Jerrod Johnson, who was held out of team drills last spring after shoulder surgery that eventually derailed his senior season.
• Christine's back. Christine Michael missed the second half of the season with a broken leg, giving way to Cyrus Gray's rise among Big 12 backs. It should make Texas A&M's depth at the position even more impressive, but we'll see how Michael looks coming back from the injury.

TEXAS TECH RED RAIDERS

Spring practice starts: February 19

Spring game: March 26

What to watch:

• Past defending that pass defense. Texas Tech had the Big 12's worst pass defense last season, but has a pair of big potential players at cornerback in rising sophomores Tre Porter and Jarvis Phillips. Starters LaRon Moore and Franklin Mitchem are gone, but if returning starters Cody Davis and Will Ford can continue to mature, the defense should improve in the area most important for success in the Big 12.
• And they're off! There's a four-man quarterback derby set in Lubbock this spring between Seth Doege, Jacob Karam, Michael Brewer and Scotty Young. I don't expect it to be settled until midway through fall camp, similar to last season, but there should be a solid front-runner and more clarity after spring. Coach Tommy Tuberville was extremely impressed with Doege and Karam last spring after Taylor Potts and Steven Sheffield went down with injuries.
• Time to find new stars. Most of the big names on Texas Tech's defense are gone. Colby Whitlock, Bront Bird, Brian Duncan will all continue their careers elsewhere. The leaders on the defense will have to begin to emerge in the spring. Is it Scott Smith? Cody Davis? A younger, unexpected player? We'll find out. Sometimes these types of situations aren't as easy to predict as they might seem, like Missouri's strength in 2010 emerging in the secondary.

Iowa tight end Allen Reisner and his classmates envisioned a very different path to their senior season.

They had won 20 games the previous two years and helped Iowa claim back-to-back bowl championships (Outback, Orange). Iowa entered this season ranked in the top 10 nationally primarily because of its large and decorated senior class led by national awards candidate Adrian Clayborn.

But things didn't go according to plan, as the Hawkeyes dropped five games, including the final three in November. All five losses came by seven points or fewer and four featured blown leads in the fourth quarter, a surprise for a team that finished games well the previous two seasons.

"No one's happy with the record," Reisner said. "We worked hard and we didn’t want to be where we’re at right now. We’ve just got to keep working."

The beauty of the bowl season is it provides one final opportunity to get things right. Iowa's seniors still can end their careers on a strong note Tuesday night with a win against Missouri in the Insight Bowl.

The Hawkeyes can win three consecutive bowl games for the first time in team history (they have won two straight five times).

"It's definitely big for us," Reisner said. "You want to win every game, but we really want to win this one for three straight [bowls]."

Iowa must lean on its seniors Tuesday after the rough finish to the regular season and the off-field problems that surfaced earlier this month. The team will play without record-setting receiver Derrell Johnson-Koulianos, arrested Dec. 7 on several drug charges, and starting running back Adam Robinson, suspended until January for undisclosed reasons.

Despite the turmoil, Reisner saw no need for the team to regroup before the bowl. The players are already moving forward.

"Those guys are gone," he said. "We're worried about the guys that are here now."

Robinson's suspension leaves Iowa with only one quasi-proven back in true freshman Marcus Coker. DJK's departure puts more pressure on receiver Marvin McNutt and tight ends Reisner and Brad Herman to step up in the passing game.

The good news: Iowa faced a similar situation in the 2010 Orange Bowl. Johnson-Koulianos missed most of the game with an injury, but Colin Sandeman filled in with four receptions for 53 yards and a touchdown. True freshman Brandon Wegher led the way on the ground with 113 rush yards and a touchdown.

"We've been there before," Reisner said. "Derrell wasn’t here in the last bowl game, he was hurt and Colin stepped up and had to play a huge game. We had a freshman running back last year have 100 yards rushing, and we're working for that again this year.

"Both tight ends, Brad and I, are going to have to step up big. We’re going to have to make big plays, we’re going to have to get involved, we’re going to have to get open."

Iowa will be tested by an improved Missouri defense that ranks sixth nationally in points allowed (15.2 ppg) and 41st nationally in yards allowed. Led by speedy edge rushers Aldon Smith and Jacquies Smith, the Tigers' defense reminds Reisner of Arizona's, which racked up six sacks against Iowa in a 34-27 win on Sept. 18.

The Hawkeyes hope their return to the desert brings better results Tuesday night.

"We don't want to lose four straight as seniors," Reisner said. "We’ve had a pretty good record in the four or five years we’ve all been here, and we want to keep that going."

I guess this is what they mean by getting out in front of the story.

Iowa coach Kirk Ferentz and athletic director Gary Barta held a news conference Tuesday morning where they revealed very little actual news. Despite rampant rumors about a wave of drug-related suspensions, Iowa announced no additional personnel updates other than what was released Monday night.

To recap: Top running back Adam Robinson has been suspended until January at the earliest for unspecified reasons, while running backs Jewel Hampton and Brandon Wegher are transferring. Wide receiver Derrell Johnson-Koulianos won't play for Iowa again after his arrest last week on several drug charges.

That's it.

"We don't anticipate any more announcements on our roster," Ferentz said.

You can breathe a little easier now, Iowa fans. The roster won't be depleted for the Insight Bowl matchup against Missouri on Dec. 28.

The only real news from Iowa City today is that the school reviewed its drug-testing program following the DJK mess last week and found "some flaws and inconsistencies," Barta said. The school didn't find any specific acts of cheating or any cover-up attempts by those performing the tests, but Barta has "strong evidence" to believe that student-athletes likely have found ways to get around the testing program.

He didn't go into specifics.

"We have not caught anybody getting around the system,” Barta said. “Unfortunately, there’s enough evidence in our protocol to say we have to tighten up. It’s pretty likely that someone -- I don’t know if it’s 1 or 21 -- someone has gotten around this process.

"And if it’s only one, it makes you doubt all testing.”

All Iowa student-athletes are randomly tested at least once a year by the school, including all 92 football players this year, coach Kirk Ferentz said. The Big Ten and the NCAA also conduct separate drug testing. An Iowa student-athlete automatically misses athletic competition with a first positive drug test. Those who refuse testing count as having tested positive.

A few nuggets:

• Robinson remains eligible and Ferentz hinted that his suspension is for academic reasons, stretching back to Robinson sitting out the start of the Ohio State game on Nov. 20. "It's my anticipation that he'll be back in January," Ferentz said. Hampton's decision to transfer was mutual, Ferentz said.
• The coach didn't want Robinson and Hampton to be grouped in with Johnson-Koulianos, the only Iowa player facing legal action at this time. Unfortunately, holding a news conference like this allows folks to draw those conclusions.
• Asked if other players knew about DJK's problems, Ferentz said: "My guess is some did, and if that’s the case, it’s unfortunate that nobody came forward."
• Iowa City police gave Ferentz a head's up about the DJK situation last Tuesday while the arrest was taking place.
• Ferentz on player conduct: "My guess is the behaviors of this year's team off the field aren't much different [from last season]. We had a lot of the same parties on the team last year. When you win 11 games, everything's fine, and when you win seven, it's a little different."
• Ferentz on DJK: "Shock's a strong word. I think I got over that about 20 years ago. Disappointment is obviously a big part of the equation."
• Drug testing for Iowa student-athletes continued last week, although it wasn't out of the ordinary, Barta said.
• Barta on the state of the program: "The state of the program is in great hands. We're dealing with some important and challenging issues, but I have great confidence in Kirk's handling of them."

Anyway, an odd day in Iowa City, but not a catastrophic one for the program as it prepares for the Insight Bowl.

IOWA CITY, Iowa -- One of my keys for Michigan State today was being able to take Iowa's first punch.

Well, the Hawkeyes just delivered one.

Iowa marched 80 yards in 12 plays on the game's first possession, mixing things up extremely well on offense to take a 7-0 lead. The Hawkeyes received contributions from several players, none more impressive than sophomore running back Adam Robinson, who has been the team's MVP this season. Robinson had several tough runs, including a 7-yarder to set up first-and-goal. Iowa fans, please stop talking about Brandon Wegher and appreciate the guy you have running the ball. He's been fabulous.

It's good to see Iowa get tight end Allen Reisner involved, and Marvin McNutt made a spectacular over-the-shoulder catch for a 17-yard gain.

Good stuff early from Iowa, which leads 7-0 with 7:07 left in the first quarter.

As you might have seen earlier today, Michigan State coach Mark Dantonio will once again attempt to watch his team from the press box this week at archrival Michigan.

Dantonio, released from the hospital Monday after being treated for a blood clot in his leg, is back in the office and started his news conference today by saying, "Can't keep me down Michigan week." The 54-year-old had planned to coach from the press box last week against Wisconsin but was readmitted to the hospital Thursday after doctors found the clot.

"As long as I don't have a setback, that’s where I'll be," Dantonio said of the Michigan Stadium press box.

Dantonio feels "outstanding" and is back at the football complex after spending Sunday and Monday watching film. He watched the Wisconsin game from the hospital, where he communicated with his assistants at Spartan Stadium.

"I'll take it easy, I won’t overdo things, I’ll listen to what people are telling me, I’ll listen to my body," Dantonio said. "But at the same time, I feel very good."

It's encouraging to hear Dantonio is doing well again, and while I'm not a doctor, allowing him to spend three-plus hours on his feet Saturday following a blood clot probably isn't a wise move. Hopefully, he'll spend the game in Michigan's spacious and luxurious new press box.

Other Big Ten health nuggets:

• Ohio State coach Jim Tressel confirmed that safety-linebacker Tyler Moeller is out for the year with a torn pectoral muscle that will require surgery later this week. Moeller is a big loss after leading Ohio State in both tackles for loss (4.5) and forced fumbles (2). I'll be stunned if he doesn't receive a sixth year of eligibility from the NCAA, so we should see him back in 2011. Freshman Christian Bryant will step in for Moeller, although Tressel said Jermale Hines also can play the "star" position in Ohio State's nickel package. Nate Oliver also is getting healthy and should be able to help.
• Buckeyes starting quarterback Terrelle Pryor should be fine for Saturday's game against Indiana. Pryor, who missed two series with a strained quad against Illinois, might be limited in practice early this week but will "get as close to 100 percent as one can be" for the Hoosiers.
• Speaking of Indiana, starting cornerback Richard Council will miss "an extended period of time" with a knee injury, coach Bill Lynch said. Council's injury isn't season ending at this point, but Indiana will turn to others, namely Adrian Burks, as well as Greg Heben and juco transfer Andre Kates, to fill the void.
• Not a health note, but a personnel nugget regarding Brandon Wegher. There had been some buzz about the running back returning to Iowa, but it's not happening. "If he comes back, we'll let you know," coach Kirk Ferentz said. "As far as I know, he's gone for at least this season and maybe forever."
• The hits keep coming for Purdue, as coach Danny Hope said receiver Justin Siller will miss three to six weeks with a sprained foot. The good news is the Boilers are getting healthier at running back as players like Al-Terek McBurse and Keith Carlos improved during the bye week. Purdue can move Antavian Edison and O.J. Ross back to receiver.
• Penn State linebacker Gerald Hodges and receiver Curtis Drake are improving from their injuries but likely won't be back for a little longer. Tight end Andrew Szczerba (back) started to do some light jogging but won't be back as Penn State turns to true freshman Kevin Haplea as its starter against Illinois. Defensive tackle Jordan Hill (ankle) is expected to play Saturday.
• Finally, some good news about Minnesota receiver Connor Cosgrove, who last month was diagnosed with leukemia. He's doing well and was in the locker room before last week's game against Northwestern. "The leukemia counts in his body are way down," Gophers coach Tim Brewster said. "His body is reacting positively to the chemotherapy. The outlook for Connor is really positive." Great to hear.

Hope you had a great weekend. I'm pretty certain you had more fun than Rich Rodriguez. Or my media pals wasting away outside Michigan's NCAA hearing in Seattle (at least they got some Domino's pizza, compliments of Michigan athletic director Dave Brandon, the former Domino's CEO).

Michigan's appearance before the NCAA Committee on Infractions was just one of several Big Ten news items from the weekend. Rather than address them individually, I'm consolidating them into a single post. You can thank me later.

1. Michigan appears before NCAA Committee on Infractions


What happened: Rodriguez and other Michigan officials, including Brandon and president Mary Sue Coleman, met with NCAA committee members for more than seven hours Saturday in Seattle. Michigan's primary focus was to defend Rodriguez against the NCAA's charge that he failed to promote an atmosphere of compliance at the school. The meeting was closed and no one said much about the specifics of what happened. Brandon called the hearing "fair and thorough;" at least 12 boxes of documents were presented. Rodriguez, in his only comments, said he's "certainly glad this part of the process is over." The Committee on Infractions likely will render its decision on penalties -- it could uphold Michigan's self-imposed penalties -- in 6-8 weeks, although as we found out with USC, the process could take longer.

My take: As expected, we didn't learn much, and we likely won't know much until midway through the season. A lot of this comes down to how seriously the NCAA considers these particular violations. Sure, they're categorized as major, but exceeding limits on practice/workout time and number of staff members involved with players doesn't seem as damaging as the allegations involving agents and players at several schools. There's also a widespread belief that similar violations could be found at many other programs. So does the NCAA want to make an example of Rodriguez, also named in a similar investigation involving West Virginia? We'll see. However things turn out with the NCAA or on the field this season, Michigan's strong defense of Rodriguez is the right move. The school doesn't want to be accused of not supporting its coach.

2. Iowa's Kirk Ferentz comments on absent running back Brandon Wegher

What happened: Ferentz on Saturday told reporters that there's no timetable for the return of the sophomore back, who left the team for undisclosed personal reasons about a week ago. But Ferentz is "cautiously optimistic" about Wegher rejoining the team, saying, "Personally, I can’t imagine him not coming back, but you just never know, you never know."

My take: Despite the state-wide panic about a reserve running back, it's important to have a little patience with this situation. From what I've heard, Wegher should be back with the Hawkeyes at some stage. He'll obviously fall behind in his preparation and on the depth chart, but I'd be surprised if we don't see him during the season. Although I understand the anxiety after Iowa struggled to keep its running backs healthy -- freshman Marcus Coker is already out with a shoulder injury -- Adam Robinson and Jewel Hampton are two solid options at the top.

3. Ohio State, Colorado discussing 2011 game

What happened: In response to a (Boulder) Daily Camera report, Ohio State athletic director Gene Smith released a statement Saturday saying that he's talking with Colorado about scheduling a 2011 game in Columbus. There would be no return trip to Boulder, and the game would round out Ohio State's nonconference slate, which includes a trip to Miami and home games against both Akron and Toledo. "We hope to have an announcement on that within the next month," Smith said. He added that the payout to Colorado won't be $2 million, as previously reported.

My take: This would be a win-win for Ohio State, which gets a second BCS-conference opponent on its schedule and doesn't have to return the game. Colorado, meanwhile, gets some money for its financially strapped athletic program. Ohio State often gets criticized for playing one blockbuster non-league game and three cupcakes, and while Colorado has been in the latter category for some time, the Buffaloes should be more competitive in 2011. The Buckeyes haven't played two nonconference games against BCS foes since 2003, when they faced both Washington and NC State.

4. Delany talks Big Ten title game plans

What happened: While attending Michigan's NCAA hearing, Big Ten commissioner Jim Delany spoke with reporters about the short-term and long-term plans for a league championship game in football. Not surprisingly, he's very pleased with Indianapolis as the initial site, saying it "makes a lot of logistical sense," and reiterated that the league and its athletic directors will take their time looking at long-term options.

My take: The most interesting thing Delany said was that the Big Ten could look to package its championships in football, men's basketball and women's basketball in one city. Indianapolis will host all three in 2011, but the Big Ten will consider moving its basketball tournament after attendance has been less than stellar in recent years. Chicago wants the football championship at Soldier Field and has hosted the hoops tourneys at the United Center. Cleveland, Detroit and Minneapolis also could host the basketball tournaments -- Green Bay, not so much -- but we need to take a closer look at those venues in addition to the football stadiums.

Iowa's three-man race for the starting running back job is down to two, at least for now.

Sophomore Brandon Wegher isn't practicing with the team for undisclosed reasons, according to multiple media reports. A source tells my guy Marc Morehouse that Wegher's issues aren't related to academics, but the running back's status going forward is unclear.

Asked if Wegher's status had changed earlier Tuesday, a team spokesman wrote me in an e-mail: "No change in status at this time."

Head coach Kirk Ferentz isn't expected to address Wegher's status today, although a portion of practice is open to the media.

This is definitely a wait-and-see situation. Rumors about Wegher leaving Iowa cropped up more than once during the offseason, but he attended the team's media day last Friday and seemed to be in good spirits.

Asked about the competition with fellow backs Jewel Hampton and Adam Robinson, he told the Iowa City Press Citizen, "We're all working together, we're not trying to beat each other right now. As of right now, all three of us are trying to get better as individuals to help the team."

Let's wait and see what happens here. Iowa certainly has other options at running back, but the Hawkeyes are better with Wegher in the fold. He set a team freshman record with eight rushing touchdowns and comes off of a 113-yard rushing performance against Georgia Tech in the Orange Bowl.

A few weeks ago, Rivals.com took a look at the nation's top triplets: the best quarterback/running back/wide receiver combos.

In ranking college football's top 15 triplets, Rivals singled out both Ohio State (No. 7) and Wisconsin (No. 9) from the Big Ten. The Badgers' triple threat of quarterback Scott Tolzien, running back John Clay and wide receiver Nick Toon "isn't as flashy as some others on this list but ... get the job done."

For Ohio State, Rivals lists Terrelle Pryor, Dan Herron and DeVier Posey, noting that Pryor could be a Heisman candidate and Posey "has big-time speed and is a top-flight deep threat." Whether Herron or Brandon Saine is the running back, the Buckeyes' offensive combo has the potential to be dangerous.

Both groups are deserving, although I'd probably put Wisconsin's group ahead of Ohio State's, mainly because of Clay.

Who are some other notable three-headed monsters in the Big Ten? I came up with a few.

Note: I only considered teams that had quarterbacks with Big Ten experience and weren't significantly lacking at one of the positions.

INDIANA
QB: Ben Chappell
RB: Darius Willis
WR: Tandon Doss
Rationale: I really, really like this group, especially if Willis can stay healthy. Chappell passed for 2,941 yards last season, and Doss averaged 12.5 yards per catch while ranking third in the league in receptions. Willis has home-run ability, as he showed against Michigan, Northwestern and others, and if he can develop some consistency, Indiana's combination should be very dangerous.

IOWA
QB: Ricky Stanzi
RB: Adam Robinson or Jewel Hampton or Brandon Wegher
WR: Marvin McNutt or Derrell Johnson-Koulianos
Rationale: Stanzi can be criticized for his interceptions, but he also made a ton of big plays for the Hawkeyes last season. Both McNutt and DJK can really stretch the field -- McNutt averaged 19.8 yards a catch, DJK averaged 16.7 yards a catch -- and all three running backs have proven themselves to varying degrees in big games. If pressed to choose a big-play running back and wide receiver, I'd probably go with Hampton and McNutt.

MICHIGAN STATE
QB: Kirk Cousins
RB: Larry Caper or Edwin Baker
WR: Keshawn Martin or Mark Dell or B.J. Cunningham or Keith Nichol
Rationale: Michigan State might have more overall depth at these three positions than any team in the Big Ten. Cousins passed for 2,680 yards last season, and Martin has the potential to be a major big-play receiver this fall. Both Caper and Baker showed flashes as true freshmen. If pressed to choose a running back and a receiver, I'd go with Caper and Martin.

MICHIGAN
QB: Tate Forcier or Denard Robinson
RB: Vincent Smith
WR: Roy Roundtree
Rationale: Forcier and Robinson both showcased big-play ability in 2009, the former with his arm and legs and the latter mostly with his legs. Michigan obviously has several running backs competing for playing time, but Smith boasts a lot of potential after averaging 5.8 yards a carry in limited work in 2009. Roundtree averaged 13.6 yards a catch last fall and hauled in a 97-yard touchdown from Robinson in the spring game. If I had to decide a QB, I'd go with Forcier, although both are good big-play options.

Some bad news for the Iowa Hawkeyes early Saturday, as running back Jewel Hampton was arrested following his alleged involvement in a bar fight near campus.

Hampton, 20, was charged with public intoxication and underage presence at a liquor establishment after his arrest at 1:46 a.m. Saturday. He was booked at the Johnson County jail at 2:42 a.m. and released at 3:15 a.m.

Iowa City police officers responded to Vito's, a restaurant and bar in Iowa City, following reports of a large fight at the back of the bar.

"Based on their investigation, officers determined that Mr. Hampton was actively involved in several physical confrontations within the bar," Iowa City police Lt. Bill Campbell told ESPN.com.

Another Iowa player, junior cornerback Jordan Bernstine, was also arrested at the bar and charged with public intoxication. Bernstine was booked under his given name, Jordan Morris.

Hampton is in the mix for Iowa's starting job this season after missing all of 2009 with a knee injury. He went through spring ball and did everything but full-contact drills. The Indianapolis native entered last summer as the frontrunner for the starting job before injuring his knee, first in July during voluntary workouts and then again during preseason camp. Hampton backed up Big Ten Offensive Player of the Year Shonn Greene in 2008 and rushed for 463 yards and seven touchdowns.

Hampton is expected to compete with Adam Robinson and Brandon Wegher for the top job in 2010.

Bernstine also was a candidate for a starting spot in 2009 before breaking his ankle in August and missing the season.

Iowa had enjoyed a long stretch without off-field incidents after seeing a large group of players make the police blotter between 2006-08. It will be interesting to see how Ferentz handles Hampton's and Bernstine's arrests.

UPDATE: Ferentz issued the following statement regarding Hampton and Bernstine early Saturday afternoon.

“I am aware of the incident involving Jordan Bernstine and Jewel Hampton Friday evening and at this time I am in the process of gathering all the facts concerning the incident. Until I have all the facts, I’ll have no further comment and the incident will be handled internally.”

So that's that.

Wisconsin running back John Clay might be the Big Ten's best hope for the Heisman Trophy this season, which will make you scratch your head after reading this next statement.

The Badgers can survive without him.

Not to diminish Clay's size and power, which Wisconsin would miss if he goes down, but the Badgers aren't exactly starved for running backs. Montee Ball showed flashes as a true freshman the past season, and Zach Brown boasts more experience (36 games played) than any other Big Ten backup back.

And whomever carries the ball for Wisconsin will benefit from working behind one of the nation's top offensive lines. Left tackle Gabe Carimi and guard John Moffitt get most of the buzz, but Wisconsin returns all five starters up front, as well as others like Bill Nagy who boast game experience.

The Badgers are one of several Big Ten teams who can survive the loss of a key player or two, as long as it isn't quarterback Scott Tolzien.

The reason why Ohio State has won or shared the past five Big Ten championships: their depth chart. Take the linebacker position, for example. The Buckeyes have two of the Big Ten's best in Ross Homan and Brian Rolle, but they also can turn to a guy like Etienne Sabino, or younger backers Storm Klein, Dorian Bell and Andrew Sweat. Tyler Moeller also should return to the field this fall, although he'll likely see more time at safety.

Indiana's Tandon Doss and Purdue's Keith Smith were the media's picks for the first-team All-Big Ten squad in 2009, and both players are primed for big seasons this fall. While both also would be big losses, their teams have other options. Indiana can turn to Damarlo Belcher and Terrance Turner, or younger players like Duwyce Wilson. Purdue always boasts depth at receiver and has options like Cortez Smith, Antavian Edison and Gary Bush behind Smith. And don't forget about incoming freshman O.J. Ross or Justin Siller, the reinstated former starting quarterback.

Speaking of the offensive skill positions, Michigan State and Iowa boast similar depth. Both teams have potential All-Big Ten players -- Keshawn Martin, Derrell Johnson-Koulianos, Marvin McNutt, Keith Nichol -- but can truly lean on their strength in numbers. Michigan State quarterback Kirk Cousins is a very lucky man, as he'll have four capable wideouts, three capable tight ends and at least two capable running backs at his disposal. Iowa's Ricky Stanzi also has weapons at wideout with Johnson-Koulianos and McNutt, as well as three solid options in the backfield with Jewel Hampton, Adam Robinson and Brandon Wegher.

Michigan has several areas of concern entering 2010, but offensive line shouldn't be one of them. The Wolverines return five linemen who started part or all of the past season, led by veteran guard Stephen Schilling. Michigan has five offensive linemen who have three years of experience under their belts, not to mention promising young prospects like Taylor Lewan and Michael Schofield.

Flipping to the other side of the line, look at Penn State. Sure, the Nittany Lions lose Big Ten co-Defensive Player of the Year Jared Odrick, but there's no reason to doubt defensive line coach Larry Johnson and his personnel. Penn State will have depth up front yet again with guys like Jack Crawford, Ollie Ogbu, Devon Still, Eric Latimore and Kevion Latham.

Let's take a look at three issues facing each Big Ten team heading into spring practice:

ILLINOIS

Spring practice starts: March 30

Spring game: April 24

What to watch:

• The quarterback competition. Four-year starter Juice Williams departs, and a host of young players (and one older one) are in the mix to replace him. New offensive coordinator Paul Petrino wants to shape his system around the starting signal-caller, so he'll be looking for some separation this spring. Jacob Charest got valuable playing time behind Williams in 2009, and Eddie McGee, a part-time wide receiver, has extensive playing experience at quarterback. They'll compete with redshirt freshman Nathan Scheelhaase and true freshman Chandler Whitmer, an early enrollee.
• Fixing the defense. New defensive coordinator Vic Koenning brings an impressive résumé to Champaign, but he'll be challenged to fix a unit that hasn't been right since J Leman and Co. left following the Rose Bowl run in 2007. Koenning wants to identify leaders on defense this spring and will look to players like end Clay Nurse and linebackers Ian Thomas and Martez Wilson. Illinois' most pressing needs likely come in the secondary after the team finished 100th nationally against the pass in 2009.
• Line dance. Illinois needs to get tougher and better on both lines to turn things around in 2010. The Illini tied for eighth in the Big Ten in sacks allowed last fall, and while the run game got going late, top lineman Jon Asamoah departs. Perhaps a bigger priority is finding a pass rush on defense after finishing last in the league in both sacks and tackles for loss in 2009.

INDIANA

Spring practice starts: March 23

Spring game: April 17

What to watch:

• Rebuilding the back seven on D. Indiana loses three starters in the secondary and two linebackers, including blog favorite Matt Mayberry. The Hoosiers brought in three junior college defenders, two of whom, linebacker Jeff Thomas and cornerback Lenyatta Kiles, will participate in spring practice. Needless to say, jobs are open everywhere, and coordinators Brian George and Joe Palcic will be looking for playmakers to step up. Several players are moving from offense to defense, including wideout Mitchell Evans to safety.
• End game. Indiana loses a lot of pass-rushing production as multiyear starters Jammie Kirlew and Greg Middleton depart. Both starting jobs at defensive end are open this spring, and IU will look to Darius Johnson, Terrance Thomas and others to step up and make plays.
• Willis watch. Indiana hopes 2010 is the year when running back Darius Willis becomes a superstar. Getting him through spring practice healthy will be a key first step. Willis has been impressive on the field, but he has struggled with injuries for much of his career. IU's passing attack should be very strong in 2010, and if Willis can elevate the run game, the Hoosiers should put up a ton of points.

IOWA

Spring practice starts: March 24

Spring game: April 17

What to watch:

• The offensive line. Rebuilding the offensive line is far and away Iowa's top priority heading into the 2010 season. The Hawkeyes are stacked at running back and boast a strong passing attack, but they'll struggle if things aren't solidified up front. Tackle/guard Riley Reiff blossomed last season and guard Julian Vandervelde also returns, but Iowa will look to fill three starting spots this spring.
• Refilling at linebacker and cornerback. Iowa's defense has been one of the nation's most opportunistic units the last two seasons, and players like Pat Angerer, A.J. Edds and Amari Spievey were three big reasons why. All three depart, so Iowa needs to reload at linebacker and find a shut-down corner (Shaun Prater?). The spotlight will be on guys like Prater, Tyler Nielsen and Jeff Tarpinian this spring.
• Sorting out the running back spot. Iowa is absolutely loaded at running back, but there's only one ball to be carried on a given play. The Hawkeyes likely will use a rotation in 2010, but who will be the featured back? Jewel Hampton will try to reclaim the top spot, which he lost because of a knee injury last summer. Adam Robinson filled in extremely well for Hampton in the lead role, and Brandon Wegher was one of the heroes of the Orange Bowl win.

MICHIGAN

Spring practice starts: March 14

Spring game: April 17

What to watch:

• Defense, defense, defense. Head coach Rich Rodriguez always will be known for his spread offense, but he won't be around much longer at Michigan if the defense doesn't significantly improve. A unit that ranked 82nd nationally last season loses its two best players (Brandon Graham and Donovan Warren) and must find contributors at linebacker, safety and cornerback. Help is on the way from the 2010 recruiting class, but Michigan can't afford a bad spring on defense.
• Devin Gardner. The heralded quarterback recruit enrolled early and will enter the mix this spring. Tate Forcier and Denard Robinson are the front-runners at quarterback, but Gardner might be the ultimate answer for the Wolverines. His ability to pick up the system and push Forcier and Robinson this spring will determine whether he sees the field in the fall or takes a redshirt.
• Running back. Carlos Brown and Brandon Minor depart, but Michigan once again should be good at the running back spot. Vincent Smith will miss spring ball as he recovers from knee surgery, but several others, including Michael Shaw and Fitzgerald Toussaint, will be competing throughout the 15 workouts. Shaw, who scored two touchdowns on 42 carries in 2009, could create a bit of separation with a good spring.

MICHIGAN STATE

Spring practice starts: March 23

Spring game: April 24

What to watch:

• Team morale. The residence hall incident and the subsequent fallout really rocked the Michigan State program. Head coach Mark Dantonio has yet to address the status of several suspended players, and the final outcome could impact the depth chart, particularly at wide receiver. It's important for Michigan State's team leaders -- Greg Jones, Kirk Cousins and others -- to unite the locker room in the spring and do all they can to prevent further problems.
• Line dance. Michigan State needs to improve on both the offensive and defensive lines in 2010, and it all starts this spring. The Spartans must replace left tackle Rocco Cironi and center Joel Nitchman, and they also lose top pass-rusher Trevor Anderson at defensive end. As strong as the Spartans should be at the skill positions, they need to start building around linemen like Joel Foreman and Jerel Worthy.
• Keith Nichol. The versatile junior could be moved to wide receiver, but he'll get a chance to push Cousins at quarterback this spring. Nichol's skills are too valuable to waste on the sideline, particularly if Michigan State has a pressing need at receiver, but he still could be a factor at quarterback if his improves his accuracy. The speedy Nichol could run the Wildcat in addition to serving as a wide receiver, if MSU chooses to go that route.

MINNESOTA

Spring practice starts: March 23

Spring game: April 24

What to watch:

• The coordinator and the quarterbacks. Minnesota will welcome its third offensive coordinator in as many seasons, though Jeff Horton doesn't plan to overhaul the system like Jedd Fisch did a year ago. Horton's primary task will be developing quarterbacks Adam Weber and MarQueis Gray, who both struggled last fall in the pro-style system. Weber has the edge in experience, but he needs to regain the form his showed in his first two seasons as the starter. Gray brings tremendous athleticism to the table but must prove he can succeed in a pro-style offense.
• The offensive line. Head coach Tim Brewster has insisted that when Minnesota gets the offensive line on track, things really will get rolling. The Gophers need better players and arguably tougher players up front, and the line should benefit in Year 2 under assistant Tim Davis. The group should be motivated by finishing last in the Big Ten in rushing in each of the past two seasons.
• Young defenders. Minnesota loses most of its starting defense from 2009, but fans are more excited about the young talent returning on that side of the ball. Spring ball could be huge for players like Michael Carter, D.L. Wilhite and Keanon Cooper as they transition into leading roles. The Gophers' biggest losses come at linebacker, as all three starters depart.

NORTHWESTERN

Spring practice starts: March 29

Spring game: April 24

What to watch:

• Identify a running back. The Wildcats produced an impressive string of standout running backs under former coach Randy Walker and at the beginning of Pat Fitzgerald’s tenure, but they struggled in the backfield in 2009. Northwestern returns the Big Ten’s most experienced offensive line, so identifying a primary ball carrier or two this spring is vital. Arby Fields and Scott Concannon showed a few flashes last year but must get more consistent, while Mike Trumpy will be an interesting addition to the mix.
• Polishing Persa. Dan Persa steps in at quarterback for second-team All-Big Ten selection Mike Kafka, and he’ll try to walk a similar career path. Kafka transformed himself in the offseason a year ago to become an extremely consistent passer, and Persa will need to do the same. Persa could be the best running quarterback Northwestern has had since Zak Kustok, but his size and the nature of the offense suggests he’ll need to make strides with his arm. NU also needs to see progress from backup Evan Watkins, as it lacks overall depth at quarterback.
• Reload in the secondary. Northwestern loses three starters in the secondary, including all-conference selections Sherrick McManis and Brad Phillips. Fitzgerald will lean heavily on cornerback Jordan Mabin and safety Brian Peters to lead the group, but he needs a few more players to emerge this spring. Defensive backs like Justan Vaughn have experience and must transition into featured roles.

OHIO STATE

Spring practice starts: April 1

Spring game: April 24

What to watch:

• Running back competition resumes. Brandon Saine and Dan Herron finished strong in 2009, but they can’t get too comfortable. Several young running backs, including Jordan Hall, Jaamal Berry, Jermil Martin and Carlos Hyde, will be competing for carries this spring. Saine likely has the best chance to lock down a featured role at running back, but if the hype about Berry pans out, it’ll be a dogfight.
• Pryor’s evolution. After Ohio State’s victory in the Rose Bowl, both Terrelle Pryor and Jim Tressel talked about the game being a key juncture in Pryor’s development. The junior quarterback must build on his performance this spring, especially from a passing standpoint. Ohio State can be a more balanced and more effective offense in 2010, but Pryor needs to keep making strides.
• Safety squeeze. The Buckeyes didn’t lose much from the 2009 team, but the safety spot took a hit as first-team All-Big Ten selection Kurt Coleman as well as key contributor Anderson Russell depart. Jermale Hines looks like the answer at one spot, and he’ll enter the spring with high expectations. Ohio State needs to build around Hines and identify playmakers for an increasingly opportunistic unit.

PENN STATE

Spring practice starts: March 26

Spring game: April 24

What to watch:

• Quarterback, quarterback, quarterback. No surprise here, as Penn State’s quarterback competition will be one of the Big Ten’s top storylines until September. Two-year starter Daryll Clark departs, leaving a major void under center. Sophomore Kevin Newsome played a bit last fall and has been in the system for a full season. He’ll enter the spring with a slight edge, but Matt McGloin and early enrollee Paul Jones also will be in the mix before Robert Bolden arrives this summer.
• Getting better up front. All-America candidate Stefen Wisniewski leads an offensive line that will have more experience and needs to make strides this spring. The line struggled against elite defensive fronts last year (Iowa, Ohio State) but should have more cohesion after another offseason together. The tackle spots will be interesting to watch, as Dennis Landolt departs. Penn State’s defensive line needs to shore up the middle after losing Big Ten co-Defensive Player of the Year Jared Odrick.
• Linebacker U. put to the test. Penn State has a proven track record of reloading in the defensive front seven, but it loses a lot of production, especially at linebacker. All three starting spots are open this spring, and the spotlight will turn to players like Nate Stupar, Bani Gbadyu, Chris Colasanti and others to fill the production and leadership gaps left by Sean Lee, Navorro Bowman and Josh Hull.

PURDUE

Spring practice starts: March 24

Spring game: April 17

What to watch:

• Marve watch begins. The starting quarterback job is open, and all eyes will be on Miami transfer Robert Marve. One of the nation's most decorated recruits in 2007, Marve started for the Hurricanes in 2008 but ran into problems and transferred. Slowed by an ACL injury last summer and fall, Marve will have every chance to establish himself this spring as he competes with Caleb TerBush.
• Wide-open secondary. All four starters depart in the secondary, creating plenty of competition back there this spring. Players like safety Albert Evans and cornerback Charlton Williams will be in the spotlight as they try to nail down jobs. Purdue should be better in the front seven in 2010, but you can bet opposing quarterbacks will attack an unproven secondary.
• The run defense. It's a huge priority for Purdue to improve against the run after finishing last in the Big Ten in rush defense in each of the past two seasons. Linebacker Jason Werner's return for a sixth year is huge, and Purdue boasts one of the Big Ten's top D-linemen in Ryan Kerrigan. Those two must provide leadership and foster more cohesion from the younger players around them. New D-line coach Gary Emanuel will be instrumental in the process this spring.

WISCONSIN

Spring practice starts: March 13 (break from March 29-April 2)

Spring game: April 17

What to watch:

• The secondary. Wisconsin looks pretty solid on the defensive line and at linebacker, so getting the secondary up to par will be key this spring. Safety Jay Valai is a vicious hitter, but can he become an All-Big Ten-caliber safety? Aaron Henry joins Valai at safety after struggling at cornerback in 2009. Wisconsin also will look for continued progress from corners Devin Smith and Niles Brinkley.
• Replacing Schofield. Bret Bielema told me earlier this week that the competition at defensive line is once again heating up this offseason. Wisconsin must replace first-team All-Big Ten end O'Brien Schofield, who ranked second nationally in tackles for loss (24.5) in 2009. J.J. Watt has superstar written all over him, but Wisconsin will look for more pass-rush ability from David Gilbert and Louis Nzegwu.
• The wide receivers/tight ends. Wisconsin showed at times last fall that its passing attack could be dynamic, and it will look for big things from several players this spring. Wideout Nick Toon certainly has what it takes to be a star in the Big Ten, and Lance Kendricks showed in the Champs Sports Bowl that he's a capable successor for Garrett Graham at tight end. The Badgers will look to David Gilreath, Isaac Anderson and Kyle Jefferson to fill the No. 2 wideout spot.
