Our Week 3 Big 12 power rankings:
1. Oklahoma (previous ranking: 1): The Sooners reeled off 42 unanswered points in the final three quarters to cruise to a 56-14 win over Tulane. Baker Mayfield tallied four touchdown passes.
2. Oklahoma State (2): Flat-out dominant. That's how the Cowboys looked in a 59-21 win over Pitt, one in which they led 35-0 and 49-7 at different points in the second quarter.
3. TCU (4): SMU kept things a little more interesting than the Horned Frogs would have preferred, trailing by six points early in the fourth quarter. But TCU was eventually able to put the Mustangs away 56-36. There's room for improvement for the Horned Frogs, for sure.
4. West Virginia (5): The Mountaineers cruised to an easy 59-16 win over Delaware State and start conference play next week at Kansas.
5. Kansas State (3): The Wildcats struggled and took a brutal 14-7 road loss at Vanderbilt, the first time the Commodores beat a ranked nonconference opponent since 1946. Kansas State will get a week off before opening conference play on Sept. 30 versus Baylor.
6. Iowa State (6): The improving Cyclones made quick work of Akron 41-14; had they been able to close out Iowa in Week 2, they would be 3-0. Instead, they're 2-1 with a key home date with Texas awaiting.
7. Texas Tech (7): Don't look now, but the Red Raiders are 2-0. Kliff Kingsbury & Co. pulled out a 52-45 win over Arizona State and have a key road trip to Houston coming up.
8. Texas (8): The Longhorns are now 1-2, but they certainly acquitted themselves well on Saturday night in a 27-24 double-overtime loss at USC. Defensively, this group did a 180 from Week 1, and true freshman quarterback Sam Ehlinger showed some encouraging signs with his play down the stretch.
9. Baylor (10): The Bears were in this game heading into the fourth quarter and made some big plays with new quarterback Zach Smith but still fell 34-20 to Duke. At 0-3, Baylor is off to its worst start since 1999.
10. Kansas (9): After a setback in Week 2, the Jayhawks once again took it on the chin in a 42-30 loss at Ohio. Kansas trailed by as much as 25 in the second half.
