Marcus Lattimore to Braxton Miller
Lattimore had flashed brilliance prior to a season-ending knee injury seven games into the 2011 campaign. His promise, in addition to the 800-plus yards he had racked up before being sidelined, led experts to believe he could contend for the Heisman this season. Unfortunately, Lattimore's knee balked again in 2012 as he suffered a dislocation that cost the season's final three games.
Miller was impressive in spurts during his freshman season, but wasn't considered an actual contender for any postseason awards. Between Ohio State's undefeated season and his dual-threat statistics, however, Miller picked up some momentum in the late-season Heisman discussion.
