Joe Theismann actually changed the pronunciation of his last name, so it would rhyme with "Heisman". Hence the famous "Theismann For Heisman" campaign.
Joe Theismann's last name was actually pronounced "Thees-mann" until he figured out he was a pretty good quarterback.
Theismann was a damn good quarterback, and he was MAYBE 6 feet tall. Very mobile with a decent arm. I'll never forget the game against the Giants when Lawrence Taylor snapped Theismann's leg. That pretty much ended Theismann's career.
