Well, it obviously isn't Terrell Pryor. He might have not lived up to the hype, but he has 2-1 in BCS bowl games in 3 years, with 2 BCS bowl game MVPs and a career record somewhere near 33-5. He also has a career rating over 120.
My guess is it's someone who's father was famous and only got on the team as a 5th stringer at a d3 school.
