Our Big 12 Week 4 power rankings:
1. Oklahoma (previous ranking: 1): There was no blowout in Waco, but Oklahoma's ground game took over in the fourth quarter and the Sooners held on to beat Baylor 49-41. On a day that featured several upsets, holding on for a win was just fine for the Sooners.
2. TCU (3): After losing seasons in 2004 and 2013, Gary Patterson's teams went a combined 23-2 the following year. The Horned Frogs also had a losing season last year. Which means the rest of the Big 12 better watch out -- especially after TCU's 44-31 upset of Oklahoma State.
