I'm sorry, but I find this entire argument to be retarded.
You can do the same thing about any situation:
If Wes Byrum makes a PAT against Vandy and an easy FG against Arkansas and Auburn tackles Knowshon Moreno for a loss every time he touches the ball, Auburn wins 10 games and we're not having this discussion.
If Arenas doesn't run back a kick against Tulane, if Ole Miss isn't Ole Miss, if Georgia plays two halves, if Auburn doesn't fumble twice, Alabama loses five games and Saban is on the hotseat instead of being fitted for a pedestal.
Ifs and buts aren't candy and nuts.
What MATTERS is that Gill's teams DID improve their winning percentage every season he was there. What MATTERS is that Gill's players responded to his enthusiasm and played every game as if they could win. Before Gill, Buffalo just went through the motions and picked up paychecks. He sold those guys on the fact that they COULD win.
You apply that same "what if" progressional logic to Chizik and jeezmarie, how awful he looks. His teams were statistically worse than Gills in practically every category despite having a much more solid foundation from which to work.
And who really gives a fuck anyway?
