1. Marcus Mariota So. Oregon
Mariota's insanely efficient and prolific season went downhill a bit in November, but that was a very long hill to descend so he still ended up being far and away the best quarterback in the conference. He led Oregon to 10 wins, didn't throw an interception until mid-November and led one of the best drives of the season to win The Civil War at the last second.
2. Taylor Kelly Jr. Arizona State
Kelly quietly turned in a huge season and led the Sun Devils to the South title. Kelly's dual-threat abilities took the Sun Devil offense to the next level and he had some monster games where he tore up teams with his feet and made his running game deadly in the red zone as he ran for eight touchdowns.
3. Brett Hundley So. UCLA
Hundley struggled against Oregon and Stanford but came up big in UCLA's other games and looked like he could be the best quarterback in the conference at times. Hundley falls below Kelly because he didn't win as many games, but ends up ahead of Mannion since he led the Bruins to more wins than Mannion did the Beavers.
4. Sean Mannion Jr. Oregon State
Mannion was so hot at one point that he was a legitimate Heisman candidate at fighting with Mariota to be considered the best Pac-12 quarterback, but then the schedule got tougher and he came back down to Earth. Still, Mannion put up massive numbers with more than 4,400 yards and 36 touchdowns.
5. Keith Price Sr. Washington
Price wasn't spectacular, but very efficient in leading the Huskies to the most wins they have had since 2001. Overall, Price bounced back from a disappointing 2012 season and was steady all season.
6. B.J. Denker Sr. Arizona
Denker started slow in the passing game, but picked it up as the season went on and was the best runner of all of the quarterbacks this season. Denker was huge in the Wildcats' gigantic win over Oregon, but probably can't be higher than this because of his lack of accuracy and production in the passing game.
7. Connor Halliday Jr. Washington State
Halliday threw the ball more than any other quarterback in the conference and put up a ton of yards, but his lack of touchdowns and number of interceptions really limit him and the Cougars. Still, Halliday deserves credit for getting the Cougars back to a bowl and some of his interception problems come from simply having to throw the ball every play.
8. Kevin Hogan So. Stanford
Hogan had a ton of hype coming into 2013, but really didn't live up to it. The Cardinal don't ask Hogan to do a ton, but he threw too many bad interceptions at poor times in their losses and their offense suffered from defenses completely selling out to the run because they weren't afraid of him burning them with the pass. It's not all bad for Hogan though, and he would actually be one of the top QBs in a lot of conferences.
9. Cody Kessler So. USC
Kessler started slow and was a bit of scapegoat for the Trojans' early struggles, but he came on late and was perfect in their upset of Stanford. In the end, he finished with a solid stat line and firmly grabbed hold of the starting spot, but he still has a long ways to go.
10. Jared Goff Fr. Cal
Goff was in a very tough situation, starting for a terrible Cal team as a true freshman, but he still put up numbers and limited his interceptions. He doesn't look like a star in the making yet, but looked like he could eventually be a very deadly passer in Cal's Bear Raid offense.
11. Travis Wilson So. Utah
Sadly, Wilson's future in football is in jeopardy, but before he went down with an injury, he was having a solid campaign, though he was throwing way too many interceptions. When healthy, Wilson showed the ability to put up a lot of yards and touchdowns and run the ball.
12. Sefo Liufau Fr. Colorado
It seemed like a risky move when the Buffs went to true freshman Liufau midway through the season, but he showed some signs of a bright future and ended up with at least average stats for a true freshman.
