USC Drops to No. 18 in AP Poll

The Trojans had the week off, giving assistant coaches the chance to recruit across Los Angeles and beyond, but plenty of great Pac-12 games unfolded in the wee hours of the night. Led by No. 2 Oregon, who survived an upset bid by Washington State up in Pullman, the Pac-12 landed five teams inside the top-18 overall rankings.

The Pac-12 South, led by the three-headed monster of UCLA, ASU and USC (down one spot from last week) all rest in good standing as the heart of Pac-12 play really gets rolling in the weeks to come. The Bruins and Sun Devils will headline next week's action with a ranked matchup of division favorites on Thursday night.

USC hosts Oregon State, who beat San Diego State 28-7 in Reser Stadium while the 4-0 Arizona Wildcats head up to Eugene, Oregon for a revenge meeting with the Oregon Ducks. Time for the Pac-12 to really drive you crazy with all these close games pitting teams of very equal talent across the board.
