Barnes involved in tussle

Matt Barnes showed his feisty side during a pro-am game Wednesday night in San Francisco, reportedly slapping an opposing assistant coach in the face after a testy exchange along the sideline. Barnes was initially upset with a referee's call and then the coach added to his frustration by joining the conversation. Barnes told AOL Fanhouse:

"Some people do too much or talk too much, and there's only so much you can take. It's hard. It's definitely hard when the refs have it out for you, saying 'Oh, you're in the NBA, so you don't get this (call) and we're going to call this.' Then the coach is talking and completely disrespecting me. "It's frustrating, but at the same time I've got to keep my composure because I'm a professional and I get paid to do this. I lost my professionalism for a little while, but I regained my composure and we won a championship tonight."
