Heisman curse: The Heisman curse is a term coined to reference a two-part assertion of a negative future for the winning player of the Heisman Trophy.  The "curse" supposes that any college football player who wins the Heisman plays on a team that will likely lose its subsequent bowl game.  The trend of post-award failure has garnered the attention of the mainstream media.  Talk of a curse in relation to bowl results was particularly prevalent from 2003 to 2008, when six Heisman Trophy winners compiled a cumulative 1–5 bowl game record, and five of those six led number one ranked teams into the Bowl Championship Series (BCS) National Championship Game as favorites (Heisman Trophy winners, including Reggie Bush, who gave back his Heisman Trophy, are 4–8 overall in the BCS National Championship Game and College Football Playoff National Championship, although prior to 2009 they were 1–6).  Additionally, the Heisman curse asserts that in most cases a Heisman winner will have either a poor career in the National Football League (NFL), or in fact not even see such a football career at all.  Although many Heisman winners have not enjoyed success at the professional level, including players like Matt Leinart, Andre Ware, Jason White, Rashaan Salaam, Eric Crouch, Ty Detmer, Troy Smith and Gino Torretta, proponents of the "curse" rarely cite highly successful players such as Barry Sanders, Charles Woodson, Eddie George, Tim Brown, Bo Jackson, Marcus Allen, Earl Campbell, and Tony Dorsett among the notables.
