The second week of the college football season is here, which means the second week of our 247Sports Pac-12 Power Rankings.

With just one week of action there is already a lot of movement within the 12 team-rankings following four Pac-12 losses during non-conference play:

- Washington fell to Auburn in Georgia

- Arizona fell at home to BYU

- UCLA fell at home to Cincinnati

- Oregon State fell on the road at Ohio State

While teams like Oregon, USC, and Utah each won this past weekend, both teams saw a few voters drop them in their personal power rankings because of poor play.

Just like last week, the voters are also not unanimous on who is the league's best team. Washington, Stanford, USC, and Oregon all received votes for the top spot. Unlike last week, Oregon State has also started to impress a few voters who placed them ahead of the 12th spot despite giving up 77 points at Ohio State and losing by more than 40 points.

247Sports' Pac-12 sites have teamed up for a weekly Power Ranking. The voters are: Jason Scheer of Wildcat Authority, Chris Karpman of Sun Devil Source, Adam Munsterteiger of Buff Stampede, Matt Prehm of Duck Territory, Angie Machado of Beaver Blitz, R.J. Abeytia of The Bootleg, Tracy Pierson of Bruin Report Online, Ryan Abraham of USCFootball.com, Dan Sorenson of Ute Zone, Shannon Carroll of BearTerritory, Chris Fetters of Dawgman, and Brian Stultz of CougFan.

We'll release our power rankings each Monday throughout the college football season. These rankings are not based on the standings at the date of release, but instead, are rankings based on who we believe is the league's best team regardless of standing and all the way down to the team we believe is playing the worst football regardless of standing. The team with the lowest amount of points is the league's best team. The team with the most points is the league's worst team in our power rankings.
