The Los Angeles Times (Ben Bolch) reports: Calling the accusations against him “a publicity stunt,” O.J. Mayo on Wednesday emphatically denied allegations that he accepted cash and gifts in violation of NCAA rules and said his accuser might be striking back after he severed ties between them. Mayo said he would cooperate with investigations by the NCAA and Pacific 10 Conference after a report he accepted tens of thousands of dollars in prohibited extra benefits before and during the one season he played basketball for USC. “My family hasn’t accepted anything, so I’m just waiting for the NCAA to do what they have to do to prove that I haven’t done anything wrong,” Mayo said.
