that they are enforcing the rules in any kind of fair or equitable way. The simple fact is, some schools are allowed to cheat blatently and others aren't. Just look at a few recent cases:
USC - Gets hammered for an agent giving money/house to Reggie Bush. NCAA says USC either knew about it or should have known about it.
Ohio St. - Several players receive illegal benefits from car dealers, tatoo artists, etc. There is PROOF that the head coach not only knew about this, but actively tried to cover it up. The players get 6-game suspensions and the coach resigns, but otherwise OSU skates.
Miami - The guy who was providing the illegal payments/benefits to players has publicly come clean with exactly what he did and who he paid it to. He was an insider with the UM athletic dept. who was influential enough that Houston Nutt called him to talk about that coaching job instead of the AD. The players get 1-3 game suspensions, the coach is fired (he would have been fired anyway), but otherwise Miami skates.
North Carolina - A few players get relatively small amounts of illegal benefits. The players are suspended for 1 year or ruled permanently ineligible. UNC forfeits all wins for 2 years plus has scholarship reductions for the next 3 years. The NCAA hasn't yet said if these penalties are enough.
MSU - European player played against professionals, but wasn't paid. He's suspended for 1 full season + 11 games the next season.
Maryland - European player played against professionals, but wasn't paid. He's suspended for 10 games.
Like I said, the NCAA has quit even pretending that the rules apply to everybody. Some schools literally have a license to cheat.
