In the battle of words before the battle of fist, kicks, takedowns and submissions, Nick Diaz and UFC welterweight champion Georges St-Pierre squared off at the UFC 158 press conference. And man, it was a powder keg! Diaz — the psychological assassin — Â really got under GSP’s skin, cajoling the usually calm, cool and collected champ into sudden outbursts. How will this all play out Saturday? I say it will have an effect on GSP, that GSP will be boiling over with anger for Diaz embarrassing him, and that once the two get in the cage and Diaz starts his “Don’t be scared homie” routine, GSP will be putty in Diaz’s hands. What do you think?
