Expectations for Julian Sayin couldn't be much higher.  He just finished 4th in the Heisman voting, as a first year starter, throwing for 3600 yards and 32 TD's and completing an amazing 77% of his passes.  QBR 177.4 Really impressive stats for such a young QB.

I was curious how recent Heisman-winning QB's grew statistically from year 1 to year 2 as the starting QB.
