It wasn't nearly as weak as Mobilhoma's lame-ass punishment a few years back, but what Alabama got was a slap on the wrist. The NCAA is toothless.
USC will not have a hair harmed on their pretty little heads. They are the NFL franchise of LA. Hell, they have receipts for homes Reggie Bush's parents were given, copies of hotel rooms in Vegas Leinart and Bush were comped to thoughout the off-season, and boosters who admitted to paying players before they graduated, and the NCAA shrugged it off.
Nothing is going to happen to them.
You forget USC has been nailed before. Couple of times.
