Stop being butthurt over Condit/Diaz. Watch Condit's fight with Rory if you think he will "mentally break".
That being said, I think St. Pierre takes a 5 round decision. This is a very bad matchup for Condit, who was taken down and controlled by a leg bbq'd Diaz. St. Pierre also won't get swept like Kim either. His top control will be too strong.
Condit is a fighter i always feel has a shot as long as he is in there, not the kind to break at all. It was his will to win that led to him abandoning his normal aggressive style to outpoint Diaz.
If Condit was clearly losing fighting like that you can bet on him coming out aggressive against Diaz, but what was working was working and he had no reason to switch it up.
The whole reason Condit fought Diaz the way he did was because he was broken mentally long before the fight started.
He knew in his heart of hearts, or someone he trusts convinced him, that he would need to employ a drastically different and frankly underwhelming strategy to CONTROVERSIALLY WIN ON POINTS for that fight. It was a terrible fight and complete waste of Nick Diaz' time. Condit cannot afford to do that again and when he tries to turn it up on GSP he will be outclassed, just like he was every time he decided not to turn and run when Nick Diaz attacked him.
GSP vs Diaz is the real skill FIGHT in this division right now.
