The Sooners locked up the Big 12 championship with a blowout victory at Oklahoma State on Saturday.
Clemson is still No. 1 and Alabama remained No. 2. Both the Tigers and Crimson Tide head into their conference championship games Saturday needing just a victory to lock up a playoff spot. The top seed gets to play closest to home, so for Clemson a semifinal game at the Orange Bowl in Miami is also on the line against North Carolina.
Iowa is No. 4 and Michigan State is No. 5, setting up a playoff play-in game in Saturday's Big Ten title game.
