Kansas Jayhawks (5-0)For two consecutive games, the Jayhawks have looked shaky against inferior opponents. Fortunately, they get another inferior opponent this week in Colorado. Following the trip to Boulder are games against Oklahoma and Texas Tech, so Kansas would be wise to work out any last kinks Saturday.
Last game: Beat Iowa State, 41-36
Next game: Saturday vs. Colorado

Missouri Tigers (4-1)The Tigers will have had nine days to lick the wounds from their collapse against Nebraska. They can erase that pain by spoiling Oklahoma State's homecoming.
Last game: Lost to Nebraska, 27-12
Next game: Saturday at Oklahoma State

Oklahoma Sooners (3-2)Quarterback Sam Bradford is back, and he got a warmup against Baylor so he can be ready for a season-making game against Texas in Dallas. If the Sooners do beat the Longhorns, the Big 12 could be looking at a worst-case scenario for its national-title hopes: a two-loss Oklahoma that goes undefeated in conference play.
Last game: Beat Baylor, 33-7
Next game: Saturday vs. Texas in Dallas

Wisconsin Badgers (5-1)The Badgers might have upset Ohio State if not for two interception returns for touchdowns and a kickoff return for a score. If quarterback Scott Tolzien can throw to the guys in red this week, the Badgers have a chance to pull off an upset.
Last game: Lost to Ohio State, 31-13
Next game: Saturday vs. Iowa
