I'm not sure even Charlie Ward is correct. Running down the Wikipedia list of winners (http://en.wikipedia.org/wiki/Heisman_Trophy#Heisman_Award_winners) reveals that (discounting Matt Leinart and Reggie Bush, who haven't been drafted yet) Ward is only the most recent Heisman winner to not be signed by an NFL team. The 2003 winner, Jason White (http://en.wikipedia.org/wiki/Jason_White_%28American_football_player%29), was signed by the Tennessee Titans as an undrafted free agent, but "he decided to retire from professional football shortly after the beginning of training camp due to knee problems." The Heisman can be a bit of a kiss of death.
