Cleveland Buck
The 2002 Buckeyes were tested week in and week out playing in the best conference in football that season. They got to the title game and knew how to play a close game against a talented opponent. 2010 Oklahoma plays in the Big XII where no one plays any defense except Nebraska. Even if they are in some 54-51 shootouts with Oklahoma State and Texas A&M, that isn't the same as a real football 20-17 football game, and they won't be ready for a real defense in their bowl game (or probably even the Big XII title game assuming Nebraska is their opponent).
