"Unfortunately, I no longer feel I can offer the level of enthusiasm to my duties that is deserved by the university, my coaching staff, my players, their families, and the supporters of Southern Cal," the letter said. "I always promised myself and my family that if I ever felt I could no longer give my full enthusiasm to a job, that I should leave it to others who could. I intend to contact my coaching staff and my players in coming days and weeks to tell them how much each of them means to me. I wish the best to USC and to my successor."
Floyd has been accused of giving money to a man who helped O.J. Mayo land with the Trojans. According to a May 12 Yahoo! Sports report, Louis Johnson -- a former confidante of Mayo -- said that Floyd gave Rodney Guillory, an associate of sports agent Bill Duffy, $1,000. Such a payment would constitute a major violation of NCAA rules.
Mayo played only one season before entering the NBA draft. He currently plays for the Memphis Grizzlies.
The Hattiesburg, Miss., native led a resurgence of USC basketball, taking the Trojans to the NCAA tournament the past three seasons.
