Coach of the year

1. Mike Riley, Oregon State: The Beavers are back in the national rankings. If they finish there, Riley could become the front-runner. Unless Oregon or Stanford goes undefeated.

2. Chip Kelly, Oregon: Ducks are atop the Pac-12 and ranked No. 2. If they ended up winning a fourth consecutive Pac-12 title and earn another berth in the national title game, Kelly wins.

2. David Shaw, Stanford: If the Cardinal eclipses Oregon in the North Division and wins the Pac-12, Shaw would have the inside track.

Keep an eye on: Todd Graham, Arizona State; Jim Mora, UCLA.
