According to Marc Spears, Los Angeles native and Golden State star point guard Baron Davis engaged in some trash-talking with heralded Southern Cal freshman point guard O.J. Mayo at UCLA during a game of pickup basketball game on Monday. Apparently, Baron got upset with Mayo after he didn’t respect one of Davis’ calls and told O.J. that he doesn’t know who he is other than the fact that he wasn’t from Los Angeles and he also needed to respect a veteran’s call. That didn’t stop Mayo from holding his own during the games, even with LeBron James in attendance watching.
