Despite Oregon and USC losing last weekend, the Pac-12 has eclipsed the Big 12 for the No. 2 spot in the ESPN.com Stats & Info Conference Power Rankings.
From Stats & Info:
The biggest difference between the Pac-12’s losses and Kansas State’s loss to Baylor is that Kansas State lost to an unranked opponent. As a result, Baylor did not pick up any of the 387 AP votes that Kansas State lost. In comparison, Stanford and UCLA gained a combined 308 AP votes and rose five spots in the AP poll with their victories. Those numbers cancel out Oregon’s fall from 1st to 5th in the AP Poll.
The Big 12 continues to be ranked first by the computers, but its lack of top-level teams has hurt the conference in the AP Poll. Both the Big 12 and Pac-12 have four teams ranked in the AP Poll, but the Pac-12’s teams are ranked comparatively higher.
The SEC gained ground in the No. 1 spot. It's nearly 13 points ahead of the Pac-12.
And the Pac-12's position is precarious. It's merely 0.2 points ahead of the Big 12, and the Pac-12 will see at least two of its four top teams lose this weekend because Oregon is at Oregon State and UCLA plays host to Stanford. Further, reeling USC is playing host to No. 1 Notre Dame without starting quarterback Matt Barkley.
