Ted Miller ESPN Stats & Information is again this season compiling its Conference Power Rankings -- a system that equally weighs the AP poll and a compilation of available BCS computer rankings in order to determine which conference is the best and worst in the country -- and in its first iteration, the Pac-12 ranks fourth. Of course, conference power rankings after two weekends is an inexact science. Last year, the SEC finished first*and the Pac-10 second at season's end. The SEC is No. 1, the Big 12 is No. 2 and the Big Ten is No. 3. The computers have the Pac-12 No. 3 and the Big 12 No. 1 ahead of the SEC. This is interesting: "Conference realignment has also led to big changes within the rankings. The WAC fell 50.3 points as a result of Boise State’s switch to the MWC, and the addition of Utah and Colorado hurt the Pac-12’s conference ranking." Why is the Pac-12 so low? Looking back on the first two weeks of play, the Pac-12 lost some high profile nonconference games that hurt its ranking. Oregon’s loss to LSU and Arizona’s loss to Oklahoma State were both prime-time games with major implications in the AP Poll. Additionally, Oregon State was blown out by Wisconsin and Colorado lost by 17 points to Hawaii.Again, things are fluid. If Stanford, Oregon, Arizona State and USC continue to climb in the national rankings, and one or more teams join them, the Pac-12 could rise in the conference rankings.
