Since 1992 Heisman Trophy winners have struggled mightily in the NFL. Some have never played a down in the NFL. No Heisman Trophy winner since 1992 has won a Super Bowl, or been named conference, or NFL player of the year. Also, only four players have played in a Pro Bowl. Just two players have been named rookie of the year and taken All-Pro honors.

Eight of the seventy four Heisman Trophy winners are in the Pro Football Hall of Fame and four winners have also been named Most Valuable Player in a Super Bowl.
