The spring semester is ending across the Big 12. Most teams will take the rest of the month of May off. Intensive conditioning work will begin again next month and continue throughout the summer as Big 12 squads prepare for the upcoming season.
Here's a look at several teams with the most immediate work this summer facing them when they return.
Colorado: The Buffaloes will have to settle on a quarterback before the start of the season. Several variables are involved, including the close race between Tyler Hansen and Cody Hawkins for the starting job in spring practice, Hansen's broken thumb in the spring game and new offensive coordinator Eric Kiesau working into his new job. If the Buffaloes are to fulfill the spoiler role that some are predicting in the North Division, they need to make a real push before training camp starts in August.
Iowa State: Oh, so much work and so little time to do it. New Iowa State coach Paul Rhoads lamented he couldn't have 30 spring practices rather than the 15 mandated by the NCAA in order to help transform his program. Rhoads needs a lot of work to rebuild ISU's defense from a unit that ranked 110th in scoring defense, 112th in total defense, 116th in pass defense and 117th in pass efficiency defense. The summer will be critical as the Cyclones try to prepare for another run of high-powered Big 12 offenses.
Kansas State: Bill Snyder will be facing a big challenge to return the Wildcats to the role of a Big 12 North challenger again. His first chore will be sorting through a quarterback battle that should rage throughout training camp as South Florida transfer Grant Gilbert and heralded junior-college transfer Daniel Thomas arrive to challenge Carson Coffman. Both will be facing a crash course in learning Del Miller's offensive strategy after Coffman made a strong late push in training camp to earn the No. 1 job. And that's just the start of Snyder's work.
Oklahoma: After being called out by Coach Bob Stoops before spring practice for their lack of diligence in conditioning drills, it would behoove Oklahoma offensive linemen to stay in shape this summer. The Sooners' offensive line remains the most glaring question as the three-time defending Big 12 champions prepare this summer. Stephen Good got the start at left guard and Ben Habern flourished at center. Cory Brandon and LSU transfer Jarvis Jones also showed some development, but need much more. The group will need to work hard through strength coach Jerry Schmidt's summer drills to keep from earning Coach Bob Stoops' wrath - again.
Texas A&M: Coach Mike Sherman was nowhere near playing with a full deck after struggling through spring practice with 20 players who sat out the spring game from a group of Aggie players were treated with 19 off-season surgeries. Surprisingly, none of the Aggies' freshman class enrolled early or they could have gone a long way to staking a claim for immediate playing time. Sherman has estimated that 60 to 65 percent of those freshmen players will be able to contribute immediately. Defensive coordinator Joe Kines urged those players to arrive in shape for a shot at immediate playing time - even with their lack of college experience.
