COLUMBIA - South Carolina running back Mike Davis is one of 23 players across the country, including six in the SEC, listed as a Heisman Trophy candidate by the Las Vegas odds makers.

The junior tailback was given 20-to-1 odds of winning the Heisman Trophy, according to Bovada Sportsbook. Davis is tied with Auburn quarterback Nick Marshall and Alabama running back Derrick Henry for 10th-best odds on the list.

Quarterbacks have won the past four Heisman Trophy awards, and 12 of the past 13. Naturally, Bovada's list is quarterback-heavy, with the position occupying the top four spots. Florida State quarterback Jameis Winston - the reigning Heisman Trophy winner - was given the best odds at 5-to-2. Oregon's Marcus Mariota was second at 5-to-1, Ohio State's Braxton Miller was third at 11-to-2, and Baylor's Bryce Petty was fourth at 10-to-1.

Davis was tied for the fourth-best odds of any running back, behind Georgia's Todd Gurley (12-to-1), Alabama's T.J. Yeldon (14-to-1) and Wisconsin's Melvin Gordon (18-to-1). Six running backs have won the Heisman Trophy since 1994. The last tailback to win was Mark Ingram of Alabama in 2009.
