| ESPN.com: Oklahoma Sooners | [Print without images] |

Think OU might be a little tired? I do. It'll trek to Fort Worth this weekend to face TCU as a touchdown favorite. Oklahoma's got a lot to play for -- a possible outright Big 12 title leads the list -- but the Frogs will be a much different challenge than Oklahoma State. TCU's improved a whole lot in the past month, and has emerged as the Big 12's best defense. Oklahoma can't count on hanging 50 points against TCU, and the Frogs' physical running game rolled over Texas last week.
