On the career it's pretty debatable Butch is a better overall coach than Richt. Say anything you want about this past year, the playcalling, etc. If you're doing a true apples-to-apples comparison (recruiting classes, conference championships, draft picks, win %, etc.) it's probably pretty comparable.
I'm not, at all, saying Butch is a bad coach. I just find it hilarious how many people on these boards want his balls in their mouth. He's not coming back, ever, and even if he did, I sure wouldn't expect the same results.
