The Heisman Trophy, one of the highest individual awards in American college football, has been awarded 78 times since its creation in 1935, including 77 unique winners and one two-time winner.
Only two freshmen and three sophomores have won the Heisman Trophy Award â and all within the last seven seasons. The two freshmen are, in fact, the last two winners: quarterbacks Johnny Manziel and the youngest Heisman Trophy recipient ever, Jameis Winston. Thereâs a youth movement afoot in the winnerâs selection process. Seniors have historically won the most by far. Fifty six of the 79 winners (71 percent) have won the Heisman in their final year.
