What are the Pac-12's Heisman odds?

What are the odds a Pac-12 player wins the 2013 Heisman Trophy?

Glad you asked, because sports betting site Bovada released its 2013 Heisman Trophy odds this week -- thanks to the Big Ten blog for noticing! -- and it includes five Pac-12 players among its top 23.

Of course, Texas A&M QB Johnny Manziel tops the list with 4-to-1 odds. He became the first freshman to win the award this winter, so he'll top most preseason lists.

Ohio State QB Braxton Miller is second at 7-1, while USC WR Marqise Lee is third at 9-1.

Lee's big question is who will be throwing him the ball. He won't have much chance of winning the Heisman if the Trojans post-Matt Barkley QB play is anywhere as bad as it was in the Sun Bowl.

Oregon's Mr. Excitement De'Anthony Thomas is fifth at 10-1. His quarterback, Marcus Mariota, is 13th at 18-1.

My take: I think Mariota is the best bet for the conference to win the Heisman in 2013. His numbers were spectacular as a first-year, redshirt freshman starter -- good enough for first-team All-Pac-12 -- and even a slight uptick would make them Heisman-worthy, particularly if the Ducks are again in the national title hunt.

That, of course, is a major issue for Heisman candidates: Winning. It's rare for a Heisman winner to play for a team outside the top 10, one that isn't playing high-profile games of national interest. Recall that Manziel's top Heisman moment was when the Aggies shocked the nation by winning at No. 1 Alabama.

UCLA QB Brett Hundley is 15th at 20-1. If the Bruins win the South Division again and push into the nation's top 15, Hundley could match the dual-threat numbers of a Manziel or Mariota.

Finally, Arizona RB Ka'Deem Carey is 21st at 33-1. Carey's on the list because he led the nation in rushing last year, but he's got two issues working against him: 1) The Wildcats might not win enough for him to get noticed; 2) Carey has some off-field problems clouding things.
