(The Spread) - With only a month left of the 2013 season, let's take a look at the latest Heisman Trophy odds.

According to oddsmakers from online sports book Bovada.lv, Oregon quarterback Marcus Mariota is a 2/3 favorite to win this year's Heisman Trophy, while Florida State signal-caller Jameis Winston has the next-best odds at 6/5. Johnny Manziel of Texas A&M is 14/1, while A.J. McCarron is 16/1 and Bryce Petty of Baylor is the current long-shot at 28/1.

Mariota has thrown for 2,281 yards and 20 touchdowns to zero interceptions this season for the undefeated Ducks. He's thrown at least one touchdown pass in every game this season and also has nine rushing touchdowns on the season. If he can help lead Oregon to a Pac-12 title and a BCS championship berth, there's no reason to believe he won't be holding up the Heisman hardware in December.

Of course, Winston is challenging to become the second freshman to win the Heisman in back-to-back years. He's thrown for 2,502 yards with 24 touchdowns and six interceptions this season for the undefeated Seminoles, who are also in line to play for a BCS title after crushing Miami in their most recent contest. Winston may have lost ground in the Heisman race after throwing two interceptions against the Hurricanes, but there's no denying that he's been one of the top players in college football this season.

Despite all of the off-field hijinks this past summer, Manziel is once again having an outstanding season. He's thrown for 2,867 yards with 26 touchdowns and eight interceptions and perhaps most importantly, he's masked A&M's issues on the defensive side of the ball by leading the Aggies to several fourth-quarter wins. That said, with two losses on this year's resume, can Manziel do enough in the eyes of voters to eclipse what Mariota or Winston have done in Oregon and Florida State? Unless the Ducks or Seminoles fall over the next month, the answer to that question is likely 'no.'
