Because he's likely worn out his welcome at the major conference level . . . he got run out of Pitt by the Stache, and I don't think his style was to OB's liking either.
Heard from a former player he had all the O-Linemen on diets and restricted their junk food so they could be more trim and lien. Then when Snyd's got here, he was all WTF?!? linemen are supposed to be big, and turned the free vending machine back on. If this is true, I guess you could call it a difference in philosophy.
I don't know if anyone noticed [and they certainly didn't change the weight of the players on the online roster] but our O-Linemen were a lot bigger this year than last, and it's mostly the same guys. Fatter legs, arses, belly's, etc.
