"Slive’s first initiative was to cleanse the reputation of the SEC, which had multiple programs on NCAA probation. He did that by instructing league members to address their complaints to the SEC office in Birmingham rather than to NCAA headquarters. Beefs got squashed during closed-door meetings rather than playing out in the newspapers, and the number of SEC teams facing NCAA penalties dropped. (Whether this actually changed any behavior remains a topic of robust debate.)"
Reports are that Slive was rather heavy handed in that matter, making it clear that schools that allowed their boosters to cause needless trouble for the league by whining to the NCAA about other SEC schools would suffer from the league office.
The only thing that can ever make Moo fans behave is a calm threat like that made by a man whose face indicates that he means business.
