I don't know how anyone could honestly have this opinion. If Weber doesn't throw the ball three feet behind Stoudamire, that is a TD (instead of an INT), if Weber doesn't skip a pass to a wide open receiver in the endzone, that is a TD.
I am not proclaiming Fisch to be the next Bill Walsh, but you certainly can't blame him for Weber's inability to read a defense and throw the ball accurately (with any sort of consistancy). It is safe to say Weber is an OK MAC QB, he is a sub-par Big 10 QB.
Could his throwing accurately have anything to do with them switching his motion, something he was never fully on board with?
