Signing day is coming fast. Next Wednesday, the next round of players will sign up for their respective programs and start what could be storied careers.

Here's what each team across the Big 12 needs. You'll find Texas A&M and Mizzou on the SEC blog and West Virginia on the Big East Blog.

BAYLOR

Quarterback: This one's pretty simple. Robert Griffin III is taking his talents to the NFL early. Nick Florence is waiting to take over, and the Bears have Bryce Petty behind him, but more reinforcements at quarterback are needed. Dual-threat quarterbacks, ideally.

Defensive tackle: Baylor already was one of the nation's worst teams (102nd nationally) at stopping the run. Now it'll need to replace both its interior linemen, Nicolas Jean-Baptiste and Tracy Robertson.

Offensive linemen: Baylor's offensive line, meanwhile, has been solid. It loses junior college transfer and two-year starter Robert T. Griffin, as well as All-Big 12 center Philip Blake. John Jones, a reserve guard, also has exhausted his eligibility.

IOWA STATE

Receiver: This has been a weak spot for the team for several years, and its top overall talent, Darius Reynolds, is gone. Darius Darks is, too. Aaron Horne and Josh Lenz will be the team's best weapons in 2012, but the pair of shifty slot guys will be seniors. This position needs reinforcements.

Defensive back: The DBs have been a quiet strength for ISU, especially in 2011. Cornerback Leonard Johnson and safety Ter'Ran Benton both have exhausted their eligibility, though, and defensive backs coach Bobby Elliott left for Notre Dame. You'll see plenty of new faces in the Cyclones' secondary next year.

Defensive line: Experienced starters Stephen Ruempolhamer and Jacob Lattimer are both gone, and Iowa State has struggled to stop the run consistently the past few seasons.

KANSAS

Quarterback: Kansas landed high-profile transfers Dayne Crist (Notre Dame) and Jake Heaps (BYU), but this is still a huge position of need. Last year's starter, Jordan Webb, left the team. Quinn Mecham is out of eligibility. Heaps is sitting out his NCAA-mandated year after transferring. Crist is the starter, but he badly needs a backup, especially if Brock Berglund's transfer appeal allows him to leave.

Wide receiver: Kansas lacks a big threat at this position. It needs a talent upgrade in a big way. Oklahoma transfer Justin McCay is joining the team, but he's no guarantee to a) be granted immediate eligibility or b) become an impact player.

Defensive tackle: Kansas is thin here, too. Richard Johnson, Patrick Dorsey and Michael Martinovich are gone, and Kansas couldn't stop much of anything on defense. Some push up front could help make everything look better. A late addition to the 2012 class from a junior college seems like a no-brainer. The Jayhawks need physically mature players to contribute immediately.

KANSAS STATE

Offensive line: K-State's offensive line was much better in 2011 and could be again in 2012. It needs help replacing All-Big 12 lineman Clyde Aufner, though. Starter Colten Freeze is also gone.

Defensive line: Kansas State is bringing back about as many starters as anyone in the Big 12, but the biggest losses are along the defensive line. Kick-blocking specialist (five in 2011) Ralph Guidry is gone, along with tackle Ray Kibble. Juco transfer Jordan Voelker exploded onto the scene this year, but he's gone, too.

Defensive backs: Cornerback David Garrett leaves a huge hole behind. Tysyn Hartman may not be as talented as teammate Ty Zimmerman, but his experience leaves a big hole. Zimmerman will have to mentor a younger safety in the near future.

OKLAHOMA

Receiver: The Sooners are thin here in a big way. That was obvious late in the season when Ryan Broyles' storied college career ended a few weeks early with a knee injury. The team also lost Justin McCay (transfer) to Kansas. Jaz Reynolds and Kenny Stills are the likely top two targets, but they need help.

Tight end: This position inspired a bit of panic at the end of the season. Seniors James Hanna and Trent Ratterree are gone. Austin Haywood wasn't allowed back on the team, and two more tight ends left the team for various reasons. That left the Sooners suddenly without a scholarship player at the position returning in 2012.

Offensive line: Starting tackle Donald Stephenson must be replaced, as will guard Stephen Good, who moved in and out of the starting lineup throughout his career. The Sooners bring back a lot of talent and aren't dying for depth there, but those two will leave holes. Three more offensive line starters will be seniors in 2012.

OKLAHOMA STATE

Offensive line: The Cowboys need a whole lot of help here to fill in behind young players stepping into the starting lineup. Starters Levy Adcock, Nick Martinez and Grant Garner are gone. Backup center Casey LaBrue is gone, too. Those are two All-Big 12 linemen who leave big shoes to be filled.

Receiver: Justin Blackmon surprised no one by leaving a year early, and Josh Cooper leaves with perhaps the most underrated career of any receiver in school history. In OSU's offense, there's always room for depth here. Nine receivers had at least 19 catches in 2011. Blackmon and Cooper combined for 192, though.

Defensive ends: The pass rush was solid for Oklahoma State this year, but both starters, Jamie Blatnick and Richetti Jones, are gone. Replacing both is a necessity.

TEXAS

Receiver: Texas lacks a true game-changer at the position, though Jaxon Shipley and Mike Davis may develop into that role in 2012. Former blue-chip recruit Darius White left for Missouri, too.

Quarterback: David Ash and Case McCoy didn't show a ton of potential at quarterback this year, though Ash may grow with an offseason to prepare as starter. Garrett Gilbert got a big chunk of the work in the spring, summer 7-on-7 and fall preseason camp. Even if Ash does grow, the Longhorns need reinforcements at the position.

Linebacker: Two senior impact players are gone. Texas is left trying to replace Emmanuel Acho and Keenan Robinson, though Jordan Hicks may mature into a star in 2012.

TCU

Offensive line: TCU's offensive line is headed for some major turnover. OT Robert Deck, OG Kyle Dooley and OG Spencer Thompson are gone. Two more starters, OG Blaize Foltz and C James Fry, will be seniors in 2012.

Defensive linemen: TCU isn't losing a lot at this spot, but Ross Forrest and D.J. Yendrey will be seniors in 2012. The Horned Frogs would be well-served to prepare, and offer some depth next year.

Specialists: TCU will have to break in a pair of new starters on special teams next season. Kicker Ross Evans and punter Anson Kelton have exhausted their eligibility.

TEXAS TECH

Receiver: The Red Raiders' offense requires a lot of depth here. Tramain Swindall is the only loss at the position, but three more (Alex Torres, Cornelius Douglas, Darrin Moore) will be seniors. Douglas moved to cornerback this year after the team was racked with injury, but we'll see whether he moves back this offseason.

Offensive line: Tech has a huge need here. Four players won't be returning in 2012. Lonnie Edwards, Mickey Okafor and center Justin Keown must be replaced.

Defensive linemen: Tech's Donald Langley and Scott Smith are both out of eligibility, and juco transfer Leon Mackey will be a senior.
PARADISE VALLEY, Ariz. -- In Monday night's Fiesta Bowl, you'll see Brandon Weeden flip passes into tiny windows to athletic receivers who make acrobatic grabs. You'll see Joseph Randle shake a linebacker in the open field and turn a 5-yard gain into a 12-yard gain.

You might even see Justin Blackmon jump over somebody.

You probably won't see Oklahoma State's offensive line dominating, but that's because nobody watches what's been arguably the most impressive Cowboys unit over the past two seasons.

Maybe they should start watching.

Last year, the Cowboys were the Big 12's best line, and returned all five starters. In 2011, they've been just as good as expected, if not better, blocking for an offense that's tops in the league and No. 2 in the nation.

"We didn’t have to worry about coming into a new offense or anything like that," said tackle Levy Adcock, whose mullet you'll see poking out the back of his helmet before he cuts it next week and heads to the NFL. "All we had to do was mature on what we had, and in the spring we did that really well. In the summer, we worked together every day. We just kept getting better and communicating better and grew as a group."

Why the success? Every Cowboys offensive lineman pointed in the same direction: at offensive line coach Joe Wickline.

"We’ve got a really, really good coach. I think he’s incredible and he gets us on the right track," center Grant Garner, a first-team All-Big 12 selection, said of Wickline.

"If there was any kind of a glitch or a kink in our offensive line, he works it out, no matter what," Adcock said. "He’s just an old-school coach, and it’s never good enough, no matter how good it is."

For Oklahoma State, it's been pretty good, too. It's only gotten better since breaking in a brand-new offensive line at the beginning of the 2010 season, the first of consecutive 11-win seasons.

Why didn't they struggle longer than a few early games?

"You can give that to our coach, Joe Wickline," said left tackle Nick Martinez. "He's one of the best in the country. He's all about trying to make us one of the best offensive lines in the country."

Even after losing a top-10 pick in Russell Okung at tackle after the 2009 season, Wickline succeeded. When Oklahoma State loses three linemen who have started this season after the Fiesta Bowl, he'll try to do it again.

"Everybody was freaking out last year when we had to replace five starters, but this year, they really only have to replace two or three, and Wick is harder on the twos than he is on the ones, so I think it’ll be a seamless transition next year," Garner said. "As long as he’s here, that’s going to be the case."
STILLWATER, Okla. -- A year ago, Oklahoma State was full of question marks. None, perhaps, were bigger than what to expect out of the 1,500 pounds or so trying to pave the way for the Cowboys' new offense.

[+] EnlargeLane Taylor
Chuck Cook/US PresswireLane Taylor is part of an experienced offensive line for Oklahoma State.
"We only had one guy [Lane Taylor] that was a returning starter and he’d only played 4 or 5 games, so we didn’t know where we were at," said coach Mike Gundy.

Added quarterback Brandon Weeden: "[Offensive line] coach [Joe] Wickline, as good as he is, I expected the best, but that was kind of the unknown. Myself, I was kind of like, 'will they be able to get it done?'"

Wickline rotated a few players in and out of the starting group early in spring. Finally, in hopes of chemistry creating a "whole greater than the sum of its parts" type of situation, he decided to stick with five players.

Taylor, a sophomore and the lone returning starter, was slotted at right guard. Levy Adcock and Nick Martinez slid into the role of right and left tackle, respectively. Jonathan Rush took over at left guard. Grant Garner assumed the role of center, making up a group of four juniors and a sophomore.

"We hoped that [running back] Kendall [Hunter] and some of the wideouts we had could make plays for us and we’d overcome some deficiencies in the offensive line," Gundy said. "Later, we found out they were pretty talented and they were able to work well as a group and make some plays."

What looked like a patchwork offensive line eventually developed into one of the Big 12's best, helping pave the way for Hunter and give Weeden time to quarterback the nation's No. 3 offense.

"They were just some blue-collar guys that worked well together," Gundy said. "I think they had great leadership from their quarterback and it didn’t hurt that we had a Doak Walker candidate at running back and a Biletnikoff winner at receiver, which takes a lot of pressure off those guys."

The best news now, though? All five are back. Four starters are seniors and Taylor will enter his third season in the starting lineup as a junior.

"Experience is very important in this game at any level and at any position, and when you have experienced guys up front, it gives your quarterback a little sense of security," Gundy said, "and they feel better about themselves and he feels better about his ability to be protected and make some plays."

The line saw progress in spring. It continued into the fall.

"By the end of the year, they were rolling pretty good," Gundy said. "They didn’t just dominate people, but they were really good, sound and didn’t make a lot of mistakes. Because of that, eliminating the errors, made them a good offensive line."

The offense will have to adjust to a new play-caller and a new running back next season, but with the play of the big men up front, their tasks look significantly easier.
Here's a breakdown of three issues facing each program heading into the spring:

Baylor Bears
Spring practice starts: March 16
Spring game: April 10

1. Quarterback Robert Griffin III's surgically repaired right knee. Griffin hasn't played since tearing the ACL in his right knee in the third game of the '09 season. He recently said he's ahead of schedule in rehabilitation, but probably won’t do much during spring practice. He'll wear a heavy knee brace and won’t participate in contact drills.

2. New linebackers. The Bears lost strongside linebacker Antonio Jones and middle linebacker Joe Pawelek, who combined to make 190 tackles last season. Senior Earl Patin, who also has played some defensive end during his career, is poised to replace Pawelek in the middle. But Patin will have to hold off highly regarded youngsters Chris McAllister and LeQuince McCall, who redshirted in ’09. Senior Chris Francis is probably the top candidate to replace Jones on the strong side.

3. Safety. The Bears must replace both of their starting safeties, including All-Big 12 performer Jordan Lake, who started 36 games in a row. Junior college transfer Byron Landor and sophomore Mike Hicks will get the first looks in the spring. But they'll have to hold off incoming freshman Ahmad Dixon, one of the top prospects to ever sign with Baylor, after he arrives for fall camp.

Colorado Buffaloes
Spring practice starts: March 6
Spring game: April 10

1. Michigan transfer Toney Clemons. Buffaloes coach Dan Hawkins called Clemons his team's most exciting receiver while he sat out the '09 season under NCAA transfer rules. The cousin of Arizona Cardinals receiver Steve Breaston, Clemons could bring an interesting dynamic to the CU offense. His arrival couldn't come at a better time, either, after Markques Simas was suspended indefinitely for violating team rules.

2. Linebacker. The Buffaloes must replace their two most productive linebackers after losing Marcus Burton and Jeff Smart. The departed seniors combined to make 105 solo tackles and 6.5 sacks last season. Senior Michael Sipili is the top candidate to replace Burton in the middle, and sophomore Jon Major might get the first crack at replacing Smart on the weak side.

3. Offensive line. The unit's inconsistency has dogged Hawkins' offense in each of his first four seasons. Eight offensive linemen had significant playing time in '09, so the Buffs are looking for more stability up front. The return of sophomore guard Maxwell Tuioti-Mariner from a pair of knee injuries, and early arrival of junior college transfer Eric Richter might shore up the interior line.

Iowa State Cyclones
Spring practice starts: March 23
Spring game: April 17

1. Linebackers. The Cyclones lost each of their starting three linebackers: Josh Raven, Jesse Smith and Fred Garrin. Junior Jacob Lattimer is in line to replace Raven on the strong side, and two highly regarded sophomores are in line to fill the other spots. A.J. Klein, who had 17 tackles in 13 games as a freshman, might get the unenviable task of replacing Smith, who led the Big 12 in tackles in '09. Jake Knott, who had 23 tackles as a freshman, is the top candidate to start on the weak side.

2. Wide receiver. Iowa State lost leading receiver Marquis Hamilton, who had 50 catches for 606 yards with four touchdowns in '09. Tight end Derrick Catlett, another top receiving threat, also is gone. The good news: Junior Darius Reynolds returns from a broken leg that caused him to miss all but four games last season. Reynolds, who earned the moniker "Money" for his big-play potential, had 13 catches for 72 yards before he was hurt in practice in late September. Junior college tight end Ricky Howard enrolled in classes in January and will participate in spring practice.

3. Defensive line. Two starters will have to be replaced after ISU lost right end Christopher Lyle and tackle Nate Frere. Lyle led the team with five sacks in '09; Frere was a pretty good run-stopper. Sophomores Cleyon Laing and Roosevelt Maggitt will get strong looks at end, and senior Austin Alburtis and sophomore Jake McDonough will move into the tackle rotation.

Kansas Jayhawks
Spring practice starts: March 27
Spring game: April 24

1. Quarterback. New Kansas coach Turner Gill might have one heck of a competition on his hands. Sophomore Kale Pick is a mobile option, after averaging 11.9 yards per rushing attempt in 2009. Junior college transfer Quinn Mecham, who enrolled in classes at Kansas in January, threw for 3,091 yards with 40 touchdowns and 11 interceptions at Snow College in Utah last season.

2. Wide receiver. The Jayhawks have to replace departed stars Kerry Meier and Dezmon Briscoe, which will be no easy task. The duo combined to catch 186 passes for 2,322 yards with 17 touchdowns last season. Bradley McDougald and Johnathan Wilson were proven targets last season, but younger players such as Chris Omigie and incoming freshman Keeston Terry will have to help this fall.

3. Secondary. The Kansas defense gave up too many big passing plays and didn't create enough turnovers last season. The Jayhawks will have to replace strong safety Darrell Stuckey, who led them with 93 tackles in '09. Senior Phillip Strozier will get the first crack at replacing the heart and soul of the Kansas defense.

Kansas State Wildcats
Spring practice starts: March 21
Spring game: April 24

1. Oregon transfer Chris Harper. In 2008, Harper played wide receiver and quarterback for the Ducks as a freshman. He became the first Oregon player in eight years to run, pass and catch a touchdown in the same season. Harper, a native of Wichita, Kan., might figure into Kansas State's quarterback or wide receiver plans after sitting out the '09 season under NCAA transfer rules.

2. Quarterback battle. Harper and two other players will probably battle to replace departed senior Grant Gregory. Senior Carson Coffman, who started the '09 season at quarterback, figures to be back in the mix, along with junior college transfer Sammuel Lamur.

3. Defensive line. The Wildcats have a couple of gaping holes to fill up front defensively. End Jeff Fitzgerald, who had 40 tackles and 10 tackles for loss in '09, has to be replaced, along with tackles Daniel Calvin and Chidubamu Abana. Junior college transfer Javonta Boyd, who has already enrolled in classes, could help in the interior line.

Missouri Tigers
Spring practice starts: March 9
Spring game: April 17

1. Wide receiver. The Tigers have to replace Danario Alexander, who led the country with 1,781 receiving yards in 2009. Juniors Jerrell Jackson and Wes Kemp both caught more than 20 passes last season, but younger players like T.J. Moe and Rolandis Woodland are going to have to contribute more. Incoming freshman Marcus Lucas could help in the fall.

2. Linebacker. The Tigers bring back two of their starting three linebackers, but three-time All-Big 12 selection Sean Weatherspoon is the one who left. Sophomore Donovan Bonner heads into spring camp as the top candidate to replace Weatherspoon on the weak side, and Will Ebner and Andrew Gachkar are back at the other linebacker spots.

3. Defensive line. Two starters are gone on the defensive front: end Brian Coulter and nose tackle Jaron Baston. At least the Tigers know they’re set at one side, with end Aldon Smith coming back after totaling 19 tackles for loss and 11.5 sacks in '09. Marcus Malbrough and Jacquies Smith will battle for starting end, and Terrell Resonno could move into the vacant tackle spot.

Nebraska Cornhuskers
Spring practice starts: March 24
Spring game: April 17
What to watch:

1. Will quarterback Zac Lee keep his starting job? After Lee was plagued by inconsistency throughout the '09 season, offensive coordinator Shawn Watson is expected to open the competition during spring practice. Sophomore Cody Green, senior Latravis Washington and freshman Taylor Martinez will all be given a fair chance to win the job.

2. Defensive tackle. Nebraska fans won't see All-American Ndamukong Suh commanding double-team blocks along the line of scrimmage. Even after losing one of the most decorated players in school history, the Cornhuskers figure to be pretty good up front. Jared Crick and Baker Steinkuhler will man the middle, with Pierre Allen and Cameron Meredith entering spring camp as the favorites at ends.

3. Rex Burkhead. The sophomore burst onto the scene after Roy Helu Jr. was hurt early in the Huskers' 33-0 rout of Arizona in the Pacific Life Holiday Bowl, rushing for 89 yards with one touchdown. Burkhead was very explosive running out of the Wildcat package, so look for Watson to try and utilize him even more to make the Nebraska attack less predictable.

Oklahoma Sooners
Spring practice starts: March 8
Spring game: April 17

1. Offensive line. The Sooners have a lot of questions up front on offense, after left tackle Trent Williams and right guard Brian Simmons departed. Will junior Donald Stephenson finally be ready to contribute at left tackle after being suspended for all of the ’09 season? Will center Ben Habern be ready after breaking his leg late in the ’09 season? When will Jarvis Jones return from a broken heel?

2. Linebacker Ronnell Lewis. The sophomore had a break-out game in the Sooners’ 31-27 victory over Stanford in the Sun Bowl, finishing with six tackles and a forced fumble. With starting linebackers Keenan Clayton and Ryan Reynolds departing, Lewis will assume a starting role on the strong side. Redshirt freshman Tom Wort is projected to start in the middle, with junior Travis Lewis starting on the weak side.

3. Secondary. The Sooners have shuffled their defensive backs after losing cornerbacks Dominique Franks and Brian Jackson. Sophomore Demontre Hurst is in line to replace Franks at field cornerback, and senior Jonathan Nelson has moved from strong safety to boundary cornerback. Junior Sam Proctor is expected to replace Nelson at strong safety, and senior Quinton Carter is back at free safety.

Oklahoma State Cowboys
Spring practice starts: March 8
Spring game: April 17

1. Quarterback Brandon Weeden. The 26-year-old junior is the top candidate to replace Zac Robinson, who broke nearly every OSU passing record. Weeden was a second-round choice of the New York Yankees in the 2002 amateur baseball draft. If he can grasp new offensive coordinator Dana Holgorson's spread offense quickly, the Pokes' passing game should again be potent in 2010.

2. Defense. Defensive coordinator Bill Young will have his hands full this spring trying to replace nine starters. The only returning starters are defensive end Ugo Chinasa and strong safety Markelle Martin. The Pokes have to replace three starters on the defensive line, three linebackers and three defensive backs. Three newcomers -- linebacker Caleb Lavey and defensive backs Devin Hedgepeth and Malcolm Murray -- will get early looks in spring camp.

3. Offensive line. The Cowboys will have to replace star left tackle Russell Okung, left guard Noah Franklin, center Andrew Lewis and right tackle Brady Bond. Juniors Nick Martinez, Casey LaBrue and Grant Garner will be the top candidates to fill open starting spots.

Texas Longhorns
Spring practice starts: Feb. 26
Spring game: April 4

1. Quarterback Garrett Gilbert. The sophomore was thrust into action after Colt McCoy injured his shoulder against Alabama in the Citi BCS National Championship Game and played admirably well in tough circumstances. The Longhorns might change their identity on offense with a young quarterback under center, so developing a running game to take pressure off Gilbert might be a top priority.

2. Defense. The unit is in good hands with coordinator Will Muschamp, but he'll have to replace many of the star players from 2009. End Sergio Kindle, tackle Lamarr Houston, linebacker Roddrick Muckelroy and safety Earl Thomas are all gone. Younger players such as end Alex Okafor and tackle Tyrell Higgins will have to turn it up a notch during spring practice.

3. Wide receiver. Jordan Shipley, who was McCoy's favorite target, also departed. Seniors James Kirkendoll and John Chiles, junior Malcolm Williams and sophomore Marquise Goodwin will have to be more consistent in their route running and pass catching. Other receivers such as D.J. Monroe and DeSean Hales will be trying to crack the receiver rotation during the spring, before talented freshmen like Darius White, Mike Davis and Demarco Cobbs arrive on campus.

Texas A&M Aggies
Spring practice starts: March 23
Spring game: April 17

1. New defensive coordinator Tim DeRuyter, who built one of the country’s best units at Air Force last season. He inherits an A&M defense that was woefully porous last season and will switch to a 3-4 scheme. Nine starters are coming back on defense, including pass-rushing specialist Von Miller. DeRuyter will spend the spring trying to install his system and getting his players comfortable with it.

2. Offensive line. The Aggies must replace three starting offensive linemen: left tackle Michael Shumard, center Kevin Matthews and right tackle Lee Grimes. Juniors Joe Villavisencio and Danny Baker and sophomore Stephen Barrera have to be ready to step up this spring.

3. Special teams. The Aggies’ special teams weren’t so special last season, as they ranked 104th in net punting, 91st in kickoff return defense and 49th in kickoff returns among FBS teams. Aggies coach Mike Sherman is putting a new emphasis on special teams, which cost his team dearly in its 44-20 loss to Georgia in the Independence Bowl.

Texas Tech Red Raiders
Spring practice starts: March 7
Spring game: April 17

1. Quarterbacks. With former Auburn coach Tommy Tuberville replacing Mike Leach at Texas Tech, senior quarterbacks Taylor Potts and Steven Sheffield figure to start spring camp on a level playing field. Potts started 10 games last season, throwing for 3,440 yards with 22 touchdowns and 13 interceptions. Sheffield started two games and threw for 1,219 yards with 14 touchdowns and four picks. New offensive coordinator Neal Brown, who was hired from Troy, runs a version of the spread offense, but Tuberville will probably incorporate more of a traditional running game into the offense.

2. Defensive line. New defensive coordinator James Willis has to replace three starters on his defensive front: ends Brandon Sharpe and Daniel Howard and tackle Richard Jones. Making matters worse, the top two reserve ends in 2009 were seniors, along with the backup nose tackle.

3. Offensive line. O-line coach Matt Moore, who was retained from Leach's staff, has to replace three starters: center Shawn Byrnes, right guard Brandon Carter and right tackle Marlon Winn. Juniors Justin Keown and Mickey Okafor and sophomore LaAdrian Waddle will probably be given first crack at replacing them. Incoming junior college transfer Scott Smith could play stand-up end in Tech's 3-4 scheme, and junior college defensive tackle Donald Langley might also have an impact in spring practice.

All questions aren't settled during the course of spring practice as teams still have much work to upgrade their weaknesses heading into the season.

Obviously, some will receive a boost from incoming freshmen who will arrive later. But here's how each team's biggest liability shakes out heading into the summer.

Baylor: The Bears are desperately looking for help at offensive tackle after losing No. 2 overall draft pick Jason Smith and Dan Gay as their starters. Former Canadian firefighter Danny Watkins has established himself at Smith's old position protecting Robert Griffin's blind side. And on the right side, junior Chris Griesenbeck and redshirt freshmen Cameron Kaufhold are competing for the starting job with Tyler Junior College's Phillip Blake and Blinn College's Marquis Franklin set the arrive later this summer.

Colorado: Wide receiver has been a question mark for the Buffaloes throughout Dan Hawkins' coaching tenure. The Buffaloes return four scholarship wide receivers and had a chance to work out several new players with Scotty McKnight injured during the spring. Josh Smith and Markques Simas are the top playmakers coming out of the spring. Non-scholarship players like Jason Espinoza and Ryan Maxwell emerged, but the Buffaloes definitely need a big upgrade at the position from their arriving freshman class.

Iowa State: The Cyclones will be facing a big hole at left tackle, where two-year starter Doug Dedrick departs. It could be filled by Matt Hulbert, who started two games last season when Dedrick was hurt. Or it could be massive 354-pound junior Hayworth Hicks or freshman Brayden Burris at the position. Whoever emerges will face a huge challenge in filling Dedrick's experience as he protects the blind side of the Iowa State quarterbacks.

Kansas: Coach Mark Mangino will be facing a few huge rebuilding job at linebacker, where the Jayhawks lose key contributors Joe Mortensen, Mike Rivera and James Holt from last season. Mangino is talking about using a two-linebacker set as his base defense with fifth-year senior Jake Schermer and senior Arist Wright getting the starting jobs leaving spring practice. Sophomore Steven Johnson and converted running back Angus Quigley were competing for playing time during the spring and another boost is expected when junior linebacker Justin Springer, who is recovering from a torn ACL last season, returns in the fall.

Kansas State: Carson Coffman appeared to have claimed the starting job at quarterback -- at least for a few weeks -- after a strong effort during the latter stages of spring practice. But Coffman's late binge has to be tempered considering he is playing against the weak Kansas State secondary. So it's fair to say there are some lingering questions at the position. Coffman apparently has beaten back the challenge of challengers Collin Klein, Joseph Kassanavoid, Trey Scott and Milton McPeek. But the arrival of South Florida transfer Grant Gregory and heralded junior-college transfer Daniel Thomas will mean more competition in the summer.

Missouri: The Tigers will be facing a challenge of replacing NFL first-round draft pick Evander "Ziggy" Hood at defensive tackle to play opposite nose tackle Jaron Baston. Redshirt sophomore Terrell Resonno appeared to have claimed the job out of the spring, with Dominique Hamilton, Chris Earnhardt and converted linebacker George White perhaps earning their way into the rotation.

Nebraska: After the graduation of top receivers Todd Peterson and Nate Swift from last season, the Cornhuskers need to fill both positions. Leading returning receiver Menelik Holt appears to have a hammerlock on one position, but Niles Paul lost a chance to take a big step forward after missing the spring after he was suspended for driving under the influence. Antonio Bell was the biggest surprise, but converted I-back Marcus Mendoza, Chris Brooks, Wes Cammack and Curenski Gilleylen all showed flashes during the spring.

Oklahoma: There was concern before spring practice, considering the Sooners were replacing four-fifths of their starting offensive line with only Trent Williams back from last season's starters. And it got worse when Bob Stoops called out the young replacements because of their lack of diligence in their preseason conditioning. Williams emerged at left tackle with Brian Simmons and Stephen Good at guards, redshirt freshman Ben Habern at center and either LSU transfer Jarvis Jones or Cory Brandon at right tackle. The depth took a hit when center Jason Hannan left early in training camp and sophomore guard Alex Williams chose to leave after spring practice. The group struggled against the Sooners' talented defensive line, allowing Sam Bradford to be touch-sacked twice in three possessions in the spring game and produced only 27 rushing yards in 52 carries.

Oklahoma State: The loss of veteran center David Washington produced a huge hole in the center of the Cowboys' interior line. Andrew Lewis returns to his natural position, leaving Oklahoma State needing two new starters at guard. Noah Franklin and Jonathan Rush have staked claims to the starting positions with Anthony Morgan and Nick Martinez getting repetitions inside. This group needs to improve if it hopes to equal the standards of previous seasons, when the Cowboys led the Big 12 in rushing each of the last three seasons.

Texas: The tight end was rarely used for the Longhorns after Blaine Irby dislocated his kneecap last season against Rice. He still wasn't ready to go during the spring as Greg Smith, Ahmard Howard, Ian Harris and D.J. Grant all got work. None of them emerged. And with Irby's return remaining iffy, it means the Longhorns again could reduce the use of the tight end and utilize four-receiver sets when they want to move the ball. Don't look for the Longhorns to use the tight end much unless this production improves.

Texas A&M: The Ag
gies were wracked with injuries during the spring as projected starters Lee Grimes, Kevin Matthews and Lucas Patterson were sidelined all spring as A&M was down to only nine healthy offensive linemen for some practices. It still doesn't excuse the lack of offensive production for A&M's starting unit, which produced only 9 yards rushing on 24 carries against Texas A&M's first-string defense. Coach Mike Sherman will be counting on immediate production from an impressive group of incoming freshman at fall practice, but it's fair to characterize the Aggies' offensive line as the team's biggest spring concern -- especially after allowing 39 sacks last season and ranking last in the conference in rushing yards per game.

Texas Tech: The loss of productive starters Daniel Charbonnet and Darcel McBath left a gaping hole at safety for the Red Raiders. Junior Franklin Mitchem earned the free safety position leaving spring practice and redshirt freshman Cody Davis emerged at strong safety.Jared Flannel , Brett Dewhurst and converted linebacker Julius Howard also got some snaps at safety. It will still be a challenge to combat the explosive Big 12 defenses with such an inexperienced group at the position.
