Honestly, a good place to start this breakdown is in Nick Diaz's head. Georges St. Pierre doesn't quite have the aura of Anderson Silva, but his reputation still precedes him. Diaz, though, has never been short on confidence. I'd be surprised to see him hesitate. When he gets taken down, which he will, Diaz should throw elbows and attack with submissions to get up. He can't try to outwrestle St. Pierre or beat him in the scramble. Stand-up will be interesting. St. Pierre is better defensively, and his jab and cage awareness should keep him off the fence. Diaz can be predictable and susceptible to leg kicks, but his aggression might force St. Pierre to fight backward, which he's not used to.
