re: How many Heisman Winners have you seen play in person?

No idea. But I played bourre with crazy arse Mike Rozier a few years after the OJ trial. One of his teammates at the table told a story about Rozier standing butt arse naked at his locker when OJ Simpson came into the Oilers locker before a MNF game and Rozier couldn't get over how big of a mother frickin head OJ had and how did they find a mother frickn helmet to fit OJ's big arse head, and how did OJ's Mama not die in childbirth because of OJ's big arse head. Basically, a naked Rozier slowly circled OJ while berating him on his head size for a good 5 minutes until OJ turned and left the locker room before interviewing/glad handing any of the other players. Rozier was still talking about OJ's "big arse head" thru the prayer, pre-game speech, and national anthem.

I can no longer look at OJ and not lose my shite laughing about that story. For this reason, Mike Rozier is my favorite Heisman winner of all-time.
