Those of you who are good at history, stats and trivia might be able to help here:

With JT going down today, we just lost our second Heisman candidate in the same season (assuming we can include Braxton's injury as part of this season).  Has anything like this ever happened before to a team in the same season?  And maybe to add another twist, has it ever happened at the same position?  I don't know the answer but figured someone here might.  Seems quite unlikely, and frankly, a pretty incredible notion in the first place, which goes to show that we are incredibly blessed as Buckeyes.  Just curious.
