Our Week 2 Big 12 power rankings:
1. Oklahoma (previous ranking: 1): After a performance for the ages in Columbus, Baker Mayfield is likely the new Heisman front-runner. Not only that, but the Sooners appear to have their best defense in years to complement their flag-planting quarterback.
2. Oklahoma State (2): Mason Rudolph had another big week, but depth at linebacker is suddenly a concern heading into a game against Pitt thanks to injuries to linebackers Kevin Henry and Kenneth Edison-McGruder and a first-half suspension of LB Calvin Bundage following his targeting call at South Alabama.
3. Kansas State (3): Safety Kendall Adams outscored Charlotte by himself with a 30-yard pick-six and a 46-yard fumble return for a touchdown. The Wildcats finally face a test this weekend at Vanderbilt. But so far, so good.
4. TCU (5): After shutting down Arkansas, TCU is fourth nationally in total defense in what appears to be another vintage Gary Patterson unit. The Horned Frogs eventually will have to get more out of Kenny Hill and the offense. But this defense looks for real.
5. West Virginia (4): Coming off his sparkling Mountaineers debut, Will Grier put up 352 passing yards and five touchdowns. After two weeks, Grier is eighth nationally in Total QBR -- and the best is probably left to come as he shakes off more rust and gets more comfortable in the West Virginia offense.
6. Iowa State (6): The Cyclones will be kicking themselves for this past weekend for a long time. Iowa State could not hold a 10-point fourth-quarter lead over Iowa, which rallied to topple the Cyclones in overtime. No doubt Iowa State will be a difficult out for Big 12 opposition this season. But getting the Cy-Hawk Trophy would've gone a long way toward helping Iowa State reach its bowl dreams.
7. Texas Tech (7): After a weird Week 2 bye, the Red Raiders now face 11 straight weeks of games, including a key nonconference tilt against Houston and another against Arizona State coming up. These two games figure to set the tone for the rest of Tech's season.
8. Texas (9): It was a nice bounce-back performance for the Longhorns. But do they now have a quarterback controversy after true freshman Sam Ehlinger's strong debut? Don't look for Tom Herman to tip his hand between Ehlinger or Shane Buechele as the Longhorns prepare to go to USC.
9. Kansas (8): The Jayhawks had been making incremental progress dating to the middle of last season. Saturday, however, they took a considerable step back with an 18-point home loss against Central Michigan. The Jayhawks still have a long, long ways to go.
10. Baylor (10): It might be time for Matt Rhule to consider going with one of the young quarterbacks. This is already shaping up to be a lost season. And Arizona grad transfer Anu Solomon won't be able to help the Bears after this season.
