I agree that he is a better than average college QB and he will be just good enough to break your heart. But even though he went down earlier IMO you guys f'ed up by not sticking with Keller. In fact I think Sam would have been the perfect QB for Erickson. One rogue to another.
That decision was made by someone who's no longer here, either. However, people who think they know the details of how that whole thing went down (i.e. Carpenter/father foisted an ultimatum on Koetter) tend to form the details that best suits their needs. Truth is no one knows what went on that night except Koetter, Sam, Rudy, and their fathers.
Nothing will align Devil fans like this next statement however. I think Tui is better than him (over the course of this season he has really started responding to the spread and has had 2-3 RIDICULOUS games) and is continuing to get better every game.
When Tui's QB rating approaches Rudy's, we'll talk.
