Wednesday is the first day prep basketball players are allowed to put their commitment in writing for the 2007-08 season.  Where O.J. Mayo will play is unknown and USC isn't expecting a fax from him today.

Mayo was reportedly set to commit at the Reebok ABCDL.

"He's the mystery man, that's for sure," said rivals.com recruiting analyst Jerry Meyer. "I don't know exactly what's going on there. You hear things. You talk to people semi-close to the situation. But I don't know that anyone really knows what O.J. is thinking."

"I hear if he goes to college it more than likely will be 'SC," Meyer said. "But I think the odds are he doesn't go."
