Issues to consider heading into the 10th week of games.

Is Oregon sharp and efficient at QB? The first question here is: Who? If Darron Thomas is healthy, it's almost certain he starts. But is his knee 100 percent? Will he be able to pose a legitimate running threat? Will he be sharp throwing the ball? Even before the injury, Thomas was off-and-on as a passer this year. And then if Thomas gets replaced by Bryan Bennett, how will the redshirt freshman react to a potentially competitive game on the road against Washington? He was outstanding against Arizona State at home and solid on the road at Colorado, but this game should be more taxing. Oregon's offense can score so many ways that it doesn't have to be perfect in the passing game. Heck, sometimes it doesn't need to throw at all. But the Huskies chances of recording the upset go up substantially if the Ducks are running at 75-80 percent at QB.

Are USC and Stanford going to have letdown games? After a triple-overtime thriller, it's hard to imagine that USC and Stanford will bring their "A-games" to road dates with Colorado and Oregon State, respectively. For one, both games look like mismatches, so it's possible that players won't be as focused and intense as they normally would. And, second, both could be running on half-tanks of energy after a physical, emotional game. Don't be surprised if they both start slowly and perhaps look a little sloppy. The question is can they pull it together enough to secure a comfortable win or will they allow the Buffs and Beavs to keep things interesting?

Good Cal or bad Cal? Good Maynard or bad Maynard? California has been all over the place this year, and so has QB Zach Maynard. It appeared that he'd found his groove during a 34-10 win over Utah, but then he lost it when he threw four interceptions in a 31-14 loss at UCLA. It's certainly not all his fault. Cal has been fickle for a while, looking like a top-25 team one week, then like an FCS one the other. The Bears should beat Washington State at home. But they will have to show up to do so. And Maynard needs to be on-target or he could lose his starting job.

Will Neuheisel and/or Wulff pick up a signature win? UCLA and Washington State fans have been waiting for Rick Neuheisel and Paul Wulff to turn their sagging programs around for four years. Neither has produced results that have fans happy. Neither has a meaningful, A-list conference victory that provided a strong indication that better things were ahead (the Bruins beating Texas last year proved a mirage and was a nonconference game). If Neuheisel and the Bruins can beat Arizona State, they will take control of the Pac-12's South Division. That would seem like a win that could resonate. If Wulff and the Cougars could pick up a fourth win at Cal, then it would keep bowl hopes alive and, at worst, show the program was making clear progress.

Foles versus the Utah D: While Utah's first season in the conference has been disappointing, it's played good, consistent defense. It ranks first in the Pac-12 in total defense and second in scoring. While Arizona's season has been disappointing, QB Nick Foles can fling the rock. He ranks first in the Pac-12 in passing yards per game with 366.1, 80 more than anyone else. That matchup alone makes this game worth watching.

Washington's run defense: Oregon is No. 1 in the conference and No. 4 in the nation in rushing offense (309 yards per game). Washington's defense is best against the run. Of course, that requires qualification. Good running teams -- Nebraska and Stanford -- ran all over the Huskies. And, as a whole, the Huskies defense had been rotten, surrendering 430 yards and 33.4 points per game. If Washington is to have any chance, it must 1. find a way to at least slow down the Ducks running game; 2. force turnovers. Time for coordinator Nick Holt to earn his paycheck.

Arizona needs to run, stop the run: Utah is second in the conference with 23 sacks. That suggests that it's in Foles' best interest to hand the ball off at least a few times to slow down the Utes' pass rush. So the Wildcats shouldn't abandon the run. Meanwhile, the Wildcats defense has mostly struggled this year, but the Utes offer a limited, one-dimensional offense that relies on running back John White. That means Arizona should gang up on the line of scrimmage and force Jon Hays to throw the ball. While the Wildcats have been worse against the pass this year than the run -- opponents are completing 69 percent of their throws -- Hays has yet to show he can throw consistently and move his team down the field.

Do Colorado and/or Oregon State have anything left? Colorado is 1-8. Oregon State is 2-6. Both are coming off blowout losses. Both will be at home in front of uninspired crowds. Both are playing foes with a lot more talent than them. Both look like candidates to take a whipping. And yet. Football is a funny game. If one or the other or both come out playing with fire, they might keep things competitive. And when a game gets into the fourth quarter, crazy things can happen.
