Offensive player of the year

1. Andrew Luck, QB, Stanford: Luck ranks fifth in the nation in passing efficiency. He's completing 71 percent of his throws with 29 touchdowns and seven interceptions.

2. LaMichael James, RB, Oregon: James ranks first in the nation with 150.88 yards rushing per game and averages 7.89 yards per rush, which is the best among the top-23 rushers. He's also scored 12 touchdowns.

3. Matt Barkley, QB, USC: Barkley leads the Pac-12 with 29 touchdown passes and has six interceptions. His 278 yards passing per game ranks third in the conference. He ranks fourth in the conference in passing efficiency.

Defensive player of the year

1. Chase Thomas, LB, Stanford: Thomas is second the conference in sacks (6.5) and first in tackles for a loss (14.5). He's also forced four fumbles, which is tied for the conference lead.

2. Nick Perry, DE, USC: Perry, after recording 2.5 sacks against Washington, leads the conference with 7.5 sacks and is second in tackles for a loss with 11. He's also defended two passes and forced two fumbles, recovering one.

3. Vontaze Burfict, LB, Arizona State: Burfict ranks second on the Sun Devils with 56 tackles, with 7.0 tackles for loss and 5.0 sacks. He also has an interception, four passes defended and a fumble recovery.

Coach of the year

1. Chip Kelly, Oregon: He's on track to win his third consecutive conference title in three years as Ducks head coach. And he's a huge fan of Styx.

2. David Shaw, Stanford: If Oregon were to lose -- even if it still wins the conference -- Shaw might get the nod if he goes 11-1 in his first year after replacing Jim Harbaugh and earns an at-large berth in a BCS bowl.

3. Lane Kiffin, USC: He becomes a serious candidate if his Trojans upset Oregon on Saturday.
