It's a three-man race.
However, deciding which of those three men is leading is becoming quite difficult. Every week, Marcus Mariota, Johnny Manziel and Jameis Winston all continue to play at a high level. And while Mariota is probably at the top of the list because of his passing and rushing numbers as well as his ball security, there's a strong sentiment toward Manziel and Winston who continue to put up Heisman-caliber numbers as well.
So, it's going to come down to how each player plays against its remaining competition and how good those remaining teams are.
Mariota just beat a ranked UCLA team and plays Stanford this week, a likely ranked Oregon State team in a couple weeks and possibly another ranked team in the Pac-12 championship game. Manziel will play ranked LSU and Missouri teams in back-to-back weeks to end the regular season.
Winston's last showcase game will be this week against a Miami team that nearly lost to Wake Forest this past weekend. If Winston has a strong game against the Hurricanes, people will take notice. But he might fall off the map with Wake Forest, Syracuse and Idaho as his next three opponents before the rivalry game against Florida and a possible second meeting with the Canes.
In the end, it's going to be who makes the best impression last. Manziel won the Heisman last year by beating Alabama last in the season and could sway opinion again with a strong showing against LSU toward the end of the year.
