Lame has never been satisfied with merely succeeding. His sense of self worth requires that he do so flamboyantly, in a manner that will bring spotlights and kudos in his direction. Saban has reached well beyond his normal comfort zone in bringing in an OC with those known tendencies. This was clearly not going to last long, and Lame's highly publicized comments over the past week show why, as well as making his ego needs & lack of control all the more evident.
Sarky is a different person and has had a greater variety of life experiences than Lame. My only real gripe with Sarky over the years has been his need (yes, I think it is a need, not just a willingness) to cheat. Sarky will fit better as a Saban subordinate, and as long as he can stay away from the sauce, he will probably be a long term fit as OC for Saban. Sarky can control his ego better, will take orders without getting snippy, and is every bit as good an offensive coach as Lame (both of whom, by the way, are good fundamental offensive coaches).
Bottom line, both Lame and Sarky are high energy, capable guys. Lame will do OK at what ever football job he has until such time as his ego-driven personality flaws blow up on him. Sarky will do OK as long as he controls his addiction and is not put in a situation where he has to choose between right and wrong when wrong is easier. At this point my long term outlook for Lame is not good, because until one learns to control one's ego, sustained success is really tough. I hope that Sarkesian can stay sober. If he can do that, and if success at Alabama is easy enough that he really never has to be put in a position where he has to control his urge to cheat, then I could see him lasting at Alabama as long as Saban is there…to the benefit of them both.
