A quick roundup.
USC 18, Ohio State 15: Trojans announce themselves as national title contenders -- again -- with true freshman quarterback Matt Barkley leading a clutch 84-yard, game-winning drive amid the frenzy of the Horseshoe.
UCLA 19, Tennessee 15: The Bruins defense comes through with a goal-line stand to secure the win. Safety Rahim Moore grabbed his fourth and fifth interceptions of the season, while kicker Kai Forbath connected on 4 of 5 field goals.
Wake Forest 24, Stanford 17: Stanford blows a 17-3 halftime lead as Wake asserts itself in the second half.
Washington 42, Idaho 23: Jake Locker throws three touchdown passes as the Huskies end the nation's longest losing streak at 15 games.
Hawaii 38, Washington State 20: The Cougars fell into a hopeless 35-6 hole at the half. The good news is they fought back in the second half. The bad news is they don't look like they have the personnel to compete in the Pac-10.
California 59, Eastern Washington 7: Bears roll against an FCS team. Now, can Cal bring its "A" game on the road at Minnesota? Bears have lost four in a row on the road.
Arizona 34, Northern Arizona 17: Nic Grigsby rushed for 207 yards. Now the Wildcats set their sights on a marquee nonconference game at Iowa.
Oregon 38, Purdue 36: Oregon wins a thriller -- Purdue missed a 2-point conversion to tie -- which has to feel a lot better than events at Boise State. Still, Ducks need work on both sides of the ball.
Oregon State 23, UNLV 21: The Beavers needed a late, 12-play, 64-yard drive for the winning field goal in the waning moments to survive, but showed show grit winning a nonconference game on the road. Big showdown Saturday with Cincinnati coming to Corvallis.
