GSP will fight the same style outside of Canada that he does inside of Canada. In my opinion, it's not so much the pressure of losing in Canada as it is the pressure of losing period. St. Pierre is probably aware of just how good he is, but he has a great respect for the chinks in his armour. Perhaps too much respect (bordering on fear). Whereas someone like Anderson is so confident in the abilities he does have that he's able to disregard his weaknesses and fight with a little less caution. I maintain that if we could take Anderson's confidence and instil it in someone like GSP, the latter would be a killing machine.
Maybe GSP needs to lose to get out of this funk. Maybe being on top for so long has worn thin and the fire is gone. After the Serra defeat, you could tell that even when he didn't finish, he was legitimately TRYING to finish. He put a beating on Fitch and Penn, stopped Serra with consistent knees, finished Hughes twice, and demolished Alves. Whereas with Diaz, I was practically pleading with him to throw more knees when he had Nick in prime position to do some damage... the man just needs to find his hunger again.
To quote the mighty Bane, victory has defeated GSP.
