Nope. George reacted by WINNING THE FIGHT!!!
Winning the contest!!! ha ha, nah I'm just kidding, I really thought GSP was going to break after he got rocked from that kick, but he came back and demonstrated the heart of a champion.
Diaz is probably the most natural fighter out there though. Most guys probably get a little nervous before they're about to enter the octagon and are cautious of getting hit. With Diaz, he just doesn't care, it's crazy.
