Sherrill and Brewer were both old-school, hardnosed coaches who had a nasty dislike for each other. Brewer pretty much ruled Mississippi while Emory the Memory and Clueless Rockey were coaching. However, when Sherrill came in you could see there was a new gunfighter in town.
With Mullen vs. Nutt, it's more of an old seasoned coach versus a cocky young gun. I think Nutt might do well next season only because he always does better when he has little talent coming back and they're not highly regarded. Mullen doesn't give a **** about the old traditions or the "We's Jes' Po Mississippi State" mentality, and he's probably going bowling next season with the personnel upgrades he makes in the offseason.
