1. Texas: Texas' big-time freshmen receiving recruits Darius White and Mike Davis are on campus to compete with the remainder of the Longhorns receivers after the departures of Jordan Shipley and Dan Buckner. Whoever develops solid chemistry with quarterback Garrett Gilbert first should have a nice advantage heading into the season. Very few questions surround the Longhorns on defense, who also have exciting freshman Jordan Hicks competing for playing time at linebacker.
2. Oklahoma: Honestly, my gut tells me to slide the Sooners above the Longhorns based on coach Bob Stoops comments at media days, but I'll give the champs their due entering the preseason. Oklahoma loses its top three blockers from a season ago, and any growth from Oklahoma's eight-win team last season will have to start on the offensive line. Stoops believes it will. If it does, look for the Sooners and Longhorns to switch positions if Oklahoma earns wins against Florida State and Cincinnati while Texas beats up on Rice and Wyoming. A convincing win at Texas Tech might keep the Longhorns on top.
3. Nebraska: The Huskers quarterback issues can't end soon enough. The Big 12 blog's pick: Zac Lee. With its offensive line and quality running backs, Nebraska will be able to run the ball. If Lee can establish himself as the best passer of the group, his skills will better serve the offense than the more athletic Cody Green and Taylor Martinez. We won't know very much about how good the defense will be again this year until the Huskers' date with Jake Locker and the Washington Huskies on Sept. 18 in Seattle.
4. Missouri: A solid contender in the North, Missouri's key to hopping over the Huskers lies in the secondary. That group returns all four starters and has another experienced player in junior Kenji Jackson entering camp as a new starter at safety. If it solidifies, Missouri will be a force that spends most of the season in the top 25. Jerrell Jackson and Wes Kemp should share the spotlight catching balls from Blaine Gabbert along with slot man T.J. Moe and tight end Michael Egnew.
5. Texas A&M: The Aggies have the conference's best player, but its worst defense. Both will need to improve for the Aggies to earn a South title. On defense, new defensive coordinator Tim DeRuyter will have to build around tackle Lucas Patterson, linebacker Von Miller and safety Trent Hunter. Three freed-up offensive line spots -- which might all be filled by freshman -- will have to be solid and consistent for the offense to remain one of the Big 12's best, despite the Aggies' talent at the skill positions.
6. Kansas State: Running back Daniel Thomas led the Big 12 in rushing with almost no help from the quarterback spot last season, so the competition between Carson Coffman, Collin Klein and Sammuel Lamurisn't immensely important to Kansas State's success. No doubt, they'll be a lot better with great play from one of those three, but they won't be a bad team without it. Two of the Wildcats' top four tacklers will be junior defensive backs in 2010, Emmanuel Lamur and Tysyn Hartman.
And yes, I am very proud that I'm still batting 1.000 in not mixing up Sammuel and Emmanuel Lamur. Stay tuned, though.
7. Texas Tech: The Red Raiders have a great chance to move up this poll after hosting Texas on Sept. 18. Whoever wins the quarterback competition between Taylor Potts and Steven Sheffieldshould excel, which not every team in the Big 12 with a quarterback battle can say. Tech's aggressive new defense will have to limit big plays to see success in the first year under coach Tommy Tuberville and defensive coordinator James Willis. A convincing opening-week win against SMU will look better in December than some Tech fans might think after the team's Sunday, Sept. 5 debut.
8. Oklahoma State: One of the conference's wildcards, the Cowboys bring back just eight starters from last season, and will showcase a radical new offense in Dana Holgorsen's version of the Air Raid. Oklahoma State's receiving corps, led by Hubert Anyiam and Tracy Moore, is extremely underrated and could surprise plenty of folks in 2010. Their first real test comes Sept. 30, when they'll get a chance to knock off media darling Texas A&M in Stillwater.
9. Iowa State: The Cyclones nonconference schedule has made plenty of headlines this offseason, and Iowa State isn't shying away from its dates with Northern Illinois, Iowa and Utah. The legal issues surrounding defensive star David Sims appear to be resolved with an opening-game suspension, and running back Alexander Robinson looks ready for another big season after rushing for over 1,000 yards in his 2009 breakout season. Iowa State will need to steal a few games like last season to qualify for a second consecutive bowl game.
10. Baylor: Freshman safety Ahmad Dixon is impressing early in camp with a few big hits, and is making good on his status as one of the best recruits in Baylor history. Another -- Robert Griffin -- is already dealing with the pressures of delivering a bowl game to Waco. Coach Art Briles will need more players like Dixon and Griffin to move the Bears goals past just making a bowl game.
11. Colorado: The only team to move up from its position in the post-spring power rankings, Colorado simply brings back more talent than Kansas, and added two new receivers in UCLA non-qualifier Paul Richardson and Travon Patterson, whose transfer from USC was finalized on Monday. The offensive line has a lot of talent in Nate Solder and Ryan Miller, but the other three members will have to improve if the Buffs are going to rush for more than 1,055 yards like in 2009 (11th in the Big 12) and give up fewer than 43 sacks, 11 more than any other team in the Big 12.
12. Kansas: Losing your three best players from a team that finished last in the Big 12 North a season ago -- plus implementing a new coaching philosophy -- is a recipe for a rebuilding year. That's where the Jayhawks sit to begin 2010. They've got good young talent in linebacker Huldon Tharp and receiver Johnathan Wilson, who are both sophomores, but they face major questions at quarterback with inexperienced candidates Jordan Webb and Kale Pick battling for the No. 1 spot. Last season's leading rusher, Toben Opurum, is also nowhere to be found on the depth chart after battling injuries throughout the spring. The Jayhawks were the only team in the conference to return all five starters on the offensive line, but a season-ending injury to tackle Jeff Spikeseliminated that status. Brad Thorson, who played both guard and tackle last season, is also recovering from a broken foot. A win against Southern Miss and a competitive loss to Georgia Tech would earn the Jayhawks some more respect.
