I don’t think the NCAA has “cleared” anybody. Didn’t Emmert say that at this point it’s basically a team decision? The NCAA was in touch with schools with players mentioned in the reports. Some of those teams self-reported that they’d done investigations and reported their findings that their players did nothing wrong. The NCAA doesn’t really have anything, and they can’t ban players based on newspaper articles. If more comes out or the NCAA gets its hands on documents or other information, presumably it will act. Some teams are hoping that there isn’t anything there, or that the NCAA won’t get its hands on anything, or that it might as well go ahead and take the risk.
