Factual error: Bo Callahan is described by an interviewer as the 2014 Heisman Trophy winner. However, the film portrays the 2014 NFL Draft (albeit a fictional version of it). The Heisman Trophy is awarded in December and the winner is always linked with the year of the season that was just played (excluding bowl games). The NFL Draft takes place in late April or early May. Therefore, the 2014 Heisman Trophy wouldn't be awarded for another 7 months. Callahan would have to have been the 2013 Heisman Trophy winner if he's the most recent recipient prior to the 2014 draft.
