The race in the Pac-12 South continues to entertain. Arizona's loss to UCLA was costly, both in the standings and on the injury report. USC's loss to Oregon didn't end their title hopes as the two L.A. schools are now headed on a collision course for Nov. 17. But both need to take care of business this weekend against overmatched opponents to ensure next weekend's game sends the winner to Eugene in December. Otherwise, all eyes should be pointed northward to Palo Alto, where the Beavers come to town, and Seattle, where Utah is fighting for a bowl game.
