GSP is good at stifling the guy when he about to get some momentum. The notion that GSP wont stand more than 5 secs with Nick is questionable. GSP will stand with Nick for a good amount of time. Then after a couple of feeling out and exchanges, GSP is going to take him down before Nick starts to get loose on the feet. GSP is then going to work his GnP for a while, and again, before Nick gets comfortable off his back, is going to stand him up. Repeat. GSP wins fights like that, stifling the opponents game and frustrating him and also doing damage of his own. GSP is good at when to time stuff when he feels his hold on the fight is getting a little loose. If GSP can fight like GSP, then he will win easy. If he gets tunnel vision by going to a dark place, then he is going to play Nicks game and thats where it gets dangerous for GSP.
