The SEC has a rich tradition of turning each other in whenever possible. Tennessee would do it in a heartbeat if they had even the slightest hint of improprieties.
What do you think was the source of all those rumors about Auburn a few years ago?
They will rip their throats out given the chance.
I really don't think they are cheating...pushing the absolute limits of what can be done? Sure. But they don't have to cheat.
I believe LSU, Ole Miss, and Auburn cheat their asses off. I think Florida is probably clean...they are too focused on making that last push into the top tier of public U's to deal with that bullshit any more. UGA may or may not be...tough to get a handle on them.
