Nick Diaz beat BJ Penn at UFC 137, and his next fight will be against Georges St.Pierre. GSP has fought and beat the who's who of the division for a long time, and Diaz is one guy he hasn't squared off against. It will for sure make for an entertaining fight, as both guys could walk home with the belt.
St.Pierre has turned in many dominant performances, and he will look to do the same against Nick Diaz. Diaz will be one of the toughest guys that GSP has fought up till now.
