Our Big 12 Week 5 power rankings:
1. Oklahoma (previous ranking: 1): The Sooners had the week to heal up after a successful first month of the season. Next is a tuneup against Iowa State before the clash in Dallas with Tom Herman and Texas.
2. TCU (2): The Horned Frogs have a difficult two-game stretch coming up against West Virginia at home and Kansas State in Manhattan. If TCU can get past that, it's relatively calm waters until a showdown at Oklahoma on Nov. 11.
3. Oklahoma State (3): The Cowboys squandered several opportunities in Texas Tech's red zone but found a way to win in Lubbock.
