The SEC and the NCAA can compel Texas A&M to follow a certain set of rules if they want to belong to those organizations. Fact is the NCAA is a monopoly, but there's is no legal reason that the ~70 schools of the big-6 conferences couldn't form their own athletic association with their own rules. I actually think such a thing is eventually going to happen. I don't mean a completely separate NCAA, but I do believe there will be a splitting of the rules, i.e. the big-6 conference allow players to be paid and all the rest don't. Then we can watch semi-pro football in the big-6 and true amateurism in the rest.
