How about Brady Quinn after that video game performance? Granted, it's against BYU, but he's put up some real good numbers this year for a rejuvenated Irish offense.
As of now, I'd say Bush - Leinart - Young with Quinn on the verge of being in contention, but not there yet. If he can put up 250 and 3 TDs in a win over Tennessee in two weeks, that picture may change a bit.
'Twas a fun year, fellas.
