Well, everybody's like "Diaz got under GSP's skin" and whatnot
Well, we all know GSP's as smart as a fighter as they come and he always does calculated things.
Facing a guy like Diaz, who is very emotionnal, I believe that GSP's attitude is nothing but an act to get Diaz really into this fight emotionally, maybe even too much so the strategy goes out the window.
GSP's always starts the fight weeks in advance by picking the attitude he's going to adopt in order to put his opponent in the mindset he wants him to be.
My 2cts here, but you never know, maybe Diaz got under GSP's skin.
