I think he has done some positive things here, and I am honestly not just crapping on him, but he just isn't cutting it in big games and disappoints more often than not. While the OC is awful, he is also our 5th OC in 10 seasons and all but 1 of them sucked, too. At a certain point, it's not the OC but the HC who is the problem. Our D obviously isn't that good either and that is supposed to be Stoops strength.
While he has been an improvement over Joker, we also went to a bowl game just 1 season before we fired Joker and hired Stoops. And it took Stoops 5 years to get us back there.
