Tim Floyd

has resigned as basketball coach at Southern California following allegations that he gave $1,000 in cash to a man who helped steer former star player

O.J. Mayo

to the Trojans.

Floyd yesterday submitted a one-paragraph letter to USC athletic director Mike Garrett saying he was quitting because he no longer had full enthusiasm for his job.

In May, Yahoosports.com reported that one-time Mayo confidant Louis Johnson said Floyd made a payment of $1,000 to Rodney Guillory, a "runner" for sports agent Bill Duffy. Such a payment would be a major violation of NCAA rules.
