GSP had an absolute shite fight plan, with LOADS of room for improvement. I was stunned at how bad his fight plan was, and his execution was pretty dreadful--at least, for him.
I actually don't think we'll see him fight again, but if he does, I hope it's not bullshit pressure from dana or fans that goads him into fighting when he's not truly committed. If St. Pierre does indeed fight and he's actually focused and committed, I would be utterly shocked if the rematch shows Johny improve without any answer from Georges.
I hear that GSP only used 70% of his skills in this fight....
