There will be plenty of turnover in the Big 12 this coming season.
Texas has to replace quarterback Colt McCoy and star receiver Jordan Shipley. Oklahoma loses 2008 Heisman Trophy winner Sam Bradford and tight end Jermaine Gresham, who didn't play much at all last season, and Oklahoma State said goodbye to quarterback Zac Robinson and receiver Dez Bryant.
With spring practice right around the corner, here's a look at five position battles to watch in the Big 12 this spring:
1. Oklahoma State quarterback
Robinson leaves after breaking most of the school's passing records. He'll probably be replaced by 26-year-old junior Brandon Weeden, who was a second-round draft choice of the New York Yankees in the 2002 amateur baseball draft. Weeden played well at times last season, when he filled in while Robinson was hurt. If Weeden can grasp new offensive coordinator Dana Holgorsen's spread offense quickly, he should hold off heralded incoming freshman Nathan Sorensen during fall camp.
2. Texas defensive line
The bad news for Texas defensive coordinator Will Muschamp: star defensive end Sergio Kindle and tackle Lamarr Houston departed for the NFL draft. The good news: ends Sam Acho and Eddie Jones, who combined for 15 sacks in 2009, are both coming back. Jones might be the leading candidate to replace Kindle, but he'll have to hold off Russell Carter and promising sophomore Alex Okafor. Replacing Houston's productivity might be more problematic. Sophomore Calvin Howell, who had four tackles and one sack in 2009, was the No. 2 tackle at season's end.
3. Oklahoma offensive line
The Sooners were banged up on the offensive line last season, which contributed to their unexpected slide to 8-5. Now, OU coach Bob Stoops has to replace left tackle Trent Williams, right guard Brian Simmons and center/tight end Brody Eldridge. Will the Sooners stick with their starting tackles against Stanford in the Sun Bowl? Converted tight end Eric Mensik and rising senior Cory Brandon started against the Cardinal. Junior Jarvis Jones, who split time between guard and tackle last season, is recovering from a broken heel and might not be ready for the start of spring practice. Junior Donald Stephenson, who was suspended all of last season, might be the wild card. Junior Stephen Good and senior Tavaris Jeffries have to get better in the interior line if OU is going to improve up front in 2010.
4. Kansas quarterback
Todd Reesing, who broke about every passing mark in the Kansas record book, is gone after starting the last three seasons. Sophomore Cale Pick might remind new coach Turner Gill of his playing days at Nebraska. Pick averaged 11.9 yards per rushing attempt in seven games last season, while throwing only five passes. Pick will have to hold off junior college transfer Quinn Mecham, who enrolled in classes in January. Mecham threw for 3,091 yards with 40 touchdowns and 11 interceptions at Snow College in Utah last season.
5. Nebraska defensive line
How do you replace one of the best defensive tackles in school history? That's the dilemma Cornhuskers coach Bo Pelini will face when his team opens spring practice. All-American Ndumakong Suh is gone, along with senior defensive end Barry Turner. The good news for Nebraska is that it played several young players on the defensive line last season. Starting tackle Jared Crick had 9.5 sacks and 15 tackles for loss and was a star in his own right. Sophomore Baker Steinkuhler and junior Terrence Moore will battle for the other tackle spot. Sophomore Cameron Meredith, who had five tackles for loss and 1.5 sacks in limited time last season, is the top candidate to replace Turner on the edge.
