At last week's UFC 158 media conference call, St-Pierre and Diaz both did their best to downplay any animosity between them. We'll see how that holds up as we approach fight day, when history tells us the Stockton Bad Boy will emerge. Because trash talk, inside the cage, anyway, is part of what makes Diaz so potent. And, of course, he's talked his share of smack to GSP before.
To date, a laundry list of opponents—Matt Serra, Dan Hardy, Matt Hughes, Josh Koscheck—have tried to get inside GSP's head. All that happened was that the laundry list of opponents became a laundry list of victims. But Diaz might be a different animal. He can unglue people in there. GSP has to stay mentally strong and resist the falling of the red curtain.
