I echo what he said.
Everyone cheats to some extent, knowingly or not. There are definately obvious rules out there that people steer clear of, such as having assistants offer coaching advice and then not so obvious infractions such as the whole textbook issue. Alabama punished the guys when they found out, suspended them for 4 games or so and they even told on themselves to the NCAA. Who does that? Alabama is not going to get the death penalty over some textbook scandal. Neither will USC for giving Reggie Bush thousands of dollars. It's a crooked business that isn't run right. It is focused on dollar signs.
The truth of the matter is that the SEC is the cash cow of college football. It has been that way for awhile and will more than likely continue to be that way for awhile to come. People that aren't from the south just don't understand what college football means to southern people.
