Neither Theisman (pronounced Theesman til ND's SID got a bright idea) nor Cutler won it.....
Only 4 Heisman winners have worn #7:
John Huarte - ND - 1964.... a meh selection
Pat Sullivan - Auburn - 1971.... He certainly earned it, if nothing else for the way he played against GT
Danny Wuerffel - FL - 1996..... another meh selection
Eric Crouch - Neb - 2001..... another meh selection
Googling their sigs, none of the four fit.
If it's "#7" for the latest for their school, then USC-West (including the one reclaimed from Reggie Bush), ND, tOSU, & OU each have seven winners..... it's not Reggie Bush, Tim Brown, Troy Smith, or Kyler Murray for one very obvious reason.
Something is amiss or someone has some misinformation.
