Quick look at Week 11 Pac-12 games

Here's a quick look at Week 11 in the conference. All times are ET. All games are Saturday.

Colorado (1-5, 1-8) at Arizona (5-4, 2-4) 1:30 p.m. FX: Colorado leads the series 13-1, including a 48-29 win last year. The Wildcats' only win in the series came in 1986. Arizona could be without QB Matt Scott, who suffered a concussion in the loss Saturday at UCLA. The Buffaloes rank last in the Pac-12 in scoring offense, scoring defense, total offense and rushing defense. But Arizona ranks last in total defense and pass defense. Arizona is 11th and Colorado 12th in pass efficiency defense. The Buffs have just three interceptions all season, which ranks 113th in the nation. The Buffs have surrendered 40 sacks, tied for most in the conference. The Wildcats have just 13 sacks this season.

Arizona State (5-4, 3-3) at No. 19 USC (6-3, 4-3) 3 p.m. Pac-12 Network: The Sun Devils lead the series 18-10, including a 43-22 win last year in Tempe. That victory, however, ended an 11-game Trojans' winning streak in the series. ASU has not defeated USC in Los Angeles since a 26-15 win in the Coliseum in 1999. The Sun Devils have lost three games in a row, the Trojans two games in a row. USC ranks first in the Pac-12 in passing efficiency. Arizona State ranks first in pass efficiency defense. The Trojans pass for 312.7 yards per game, but the Sun Devils only allow 161.6 yards per game through the air. The Trojans are still seeking win No. 800. It’s the earliest USC kickoff time in the Coliseum since 1998.

No. 11 Oregon State (7-1, 5-1) at No. 14 Stanford (7-2, 5-1) 3 p.m. Fox: Stanford leads the series 50-25-3. The Cardinal has won three of the last four, including a 38-13 win last year. This game features the two best defenses in the Pac-12. Stanford is No. 1 and Oregon State No. 5 in the nation in run defense, and both are ranked in the nation's top 20 in scoring defense. Both also recently changed quarterbacks, with Kevin Hogan taking over the Cardinal's starting job from Josh Nunes, and Cody Vaz replacing Sean Mannion. The winner becomes the top challenger to Oregon in the Pac-12 North Division. Stanford visits the Ducks on Nov. 17, while the Beavers play host to them on Nov. 24.

Utah (4-5, 2-4) at Washington (5-4, 3-3) 10:30 p.m. Pac-12 Network: Washington leads the series 7-0, including a 31-14 win in Salt Lake last year. Both teams have won two in a row. Washington is the only Pac-12 school that Utah has never beaten. Utah must win two of its final three games to become bowl eligible for a 10th-straight year. The Huskies are 4-1 this season at CenturyLink Field, a record that includes wins over then-No. 8 Stanford and then-No. 7 Oregon State. According to the NCAA, Washington has played the second-toughest schedule in the nation to date while the remaining schedule ranks No. 116 in the nation. Last year, the Utes also started 0-4 in Pac-12 play before winning four straight games and five of their last six, including a Sun Bowl victory over Georgia Tech. Utah senior Reggie Dunn made NCAA history with his fourth career 100-yard kickoff return for a touchdown vs. WSU last Saturday. Going into the game, Dunn was tied for the record at three with Barry Sanders (Oklahoma State, 1986-88) and Brandon Boykin (Georgia, 2008-11). Utah is 11-0 when John White rushes for 100 yards, which he has done three times this season, including the past two games.

No. 3 Oregon (9-0, 6-0) at California (3-7, 2-5) 10:30 p.m. ESPN: California leads the series 39-34-2, including a 43-15 win last year. The last time the Ducks were in Berkeley, the Bears almost pulled a major upset against the unbeaten Ducks before succumbing 15-13. Oregon is No. 1 in the Pac-12 in scoring (54.3 ppg), total offense (561.2 yards per game) and rushing (341.2 ypg). QB Marcus Mariota is No. 1 in the conference in passing efficiency. It appears that Bears QB Zach Maynard will not play in this game due to a knee injury he suffered last Friday against Washington. His backup is Allan Bridgford.

No. 18 UCLA (7-2, 4-2) at Washington State (2-7, 0-6) 10:30 p.m. ESPN2: UCLA leads the series with the Cougars 39-18-1 and has won four in a row, including a 28-25 win last year. The Bruins have won three in a row since losing at Cal. The Cougars have lost six in a row since a 2-1 start. The Bruins are second in the conference in scoring (37 ppg), third in total offense (514.9 ypg) and second in rushing (226.2). The Cougars are allowing foes to convert 48.6 percent of their third-down plays, which marks the worst percentage in the conference. UCLA's defense has recorded 33 sacks. The Cougars have surrendered 40 sacks, tied with Colorado for worst in the conference. UCLA is ranked ahead of USC in the BCS standings for the first time since 2001.
