The BCS Ranked No. 1 Oregon Ducks continued their supremacy within the Pac-10 Conference in Week 9, along with one-loss teams Arizona and Stanford.
In a week where all ten conference teams played, the muddled-middle continues to be wide open with Oregon State beating Cal, Stanford taking down Washington, Arizona State shutting out Wazzou, Arizona beating UCLA, and USC losing to Oregon.
The following is the ninth installment of a weekly feature power-ranking the Pac-10 quarterbacks based solely on their performance in Week 9.
The Washington Huskies appeared to not even put up a fight against the Stanford Cardinal in a 41-0 loss at home in Seattle.
The up-and-down Jake Locker had his worst performance of the season, completing 7 of 14 passes for 64 yards, zero touchdowns and two interceptions.
The Washington State Cougars continued its conference losing streak with a 42-0 shutout loss against Arizona State on the road.
Quarterback Jeff Tuel had his worst performance of the season, completing 17 of 26 passes for 65 percent, 200 yards, and two interceptions.
While the numbers do not look horrible, this was the least yards he has thrown for this season, and the first time he left a contest with zero touchdowns.
The California Golden Bears just cannot win on the road this season, proving this to be true with a 35-7 loss to Oregon State.
But losing the game wasn't the only loss the Bears encountered, as starting quarterback Kevin Riley sustained a career-ending knee injury on Saturday.
Backup QB Brock Mansion stepped in to complete 14 of 24 passes for 58 percent, 128 yards and one touchdown.
The UCLA Bruins dropped their third consecutive loss against the talented Arizona Wildcats in Week 9.
With Kevin Prince out of the season due to injury, Brehaut completed 13 of 27 passes for 48 percent, 228 yards, two touchdowns, and one interception.
The USC Trojans fell to the No. 1 Oregon Ducks on Saturday, but not without a fight in their 53-32 loss.
Matt Barkley completed 26 of 49 passes for a season-low 53 percent, 264 yards, one passing touchdown, and one rushing touchdown.
Barkley threw two interceptions against Oregon, his third game this season with two-interceptions.
The Stanford Cardinal took down the Washington Huskies with ease in a 41-0 shutout in Seattle.
With NFL scouts in attendance to see the battle of the two quarterbacks (Luck vs Locker), Luck completed 19 of 26 passes for a 73 percent completion rate, 192 yards, one passing touchdown, and one interception.
Luck also added 92 yards on the ground and one rushing touchdown.
The Oregon State Beavers had no problem taking down the road-loss stricken California Golden Bears team with a 35-7 win.
Ryan Katz completed 20 of 27 passes for a season-high 74 percent, 184 yards and one touchdown.
After a rocky start to the season, Katz has stepped up and is leading his team well.
The Arizona Wildcats have their best start to a season since 1998 with a 29-21 win at UCLA.
Matt Scott, who has been filling in for an injured Nick Foles, made the most of his last start of the season before the starter returns.
Scott completed 24 of 36 passes for a 67 percent completion, 319 yards, one touchdown, and one interception.
With Scott's 71 yards of rushing, he tallied 390 total yards against the Bruins.
The Arizona State Sun Devils rebounded nicely after the loss to Cal to post a 42-0 shutout at home against Washington State.
Threet completed 26 of 32 passes for a season-high 81 percent, 300 yards, and three touchdowns.
He did all of this in just over two quarters of play, being relieved by backup Brock Osweiler with nin minutes to play in the third quarter.
This was also only Threet's second game this season without an interception.
The Oregon Ducks continued on the unbeaten path with a victory in L.A. versus the USC Trojans, landing them the No. 1 spot in the BCS Polls.
Darron Thomas completed 19 of 32 passes for a 59 percent completion rate, 288 yards, and one interception. His four passing touchdowns against the Trojans tied his career record, while he also added 42 yards on the ground.
