Oregon's loss to unranked Arizona was the chief reason the Pac-12 slipped 3.6 points in ESPN.com Stats & Information's conference power rankings.
The Pac-12 is now 14.4 points behind the top-ranked SEC and 7.8 points ahead of the No. 3 Big 12 and 8.0 points ahead of the No. 4 Big Ten.
The No. 5 ACC also could make a move, however, particularly if Stanford loses to Notre Dame on Saturday.
The ACC has three notable non-conference games against SEC opponents on Saturday as Florida State heads to Florida (12 ET, ESPN), Georgia Tech hosts Georgia (3:30 ET, ABC) and Clemson takes on South Carolina (7 ET, ESPN2). According to FPI, the ACC should be favored in all three of those games. If the ACC can go 3-0 against the SEC, it will get a boost in the Conference Power Rankings next week.
The Pac-12 remains No. 1 in Stats & Information's FPI metric, but it lags with the pollsters. Despite having five ranked teams, the Pac-12 no longer has any team ranked in the nation's top-five.
