Bowden didn't get rid of Nicely or Moore, huh? Coulda' fooled me.
If Pohl is as good a QB as Williams, of course he'll have similar numbers. That isn't and Jean Dixon-esque prediction, and taking it to the bank will only get you a stupid look from the bank teller.
The reason Williams was a back up in 1-AA was - the guy in front of him was better. If Williams were at UA for those 3 previous seasons, he'd have been a starter at the 1-A level. His logistical circumstances don't dictate is ability.
Weeden is from OK State, isn't he a starting NFL QB? Cincinnati Bengal starting QB Andy Dalton...a "system QB" at TCU, right? Missouri QB Blaine Gabbert, starting NFL QB, right? Your broad brush is lacking paint.
