Paul Heyman just posted a nice blog about Brock:
Fast-forward to today. Brock is in Las Vegas, and is already in a bad mood. He started to walked out on the UFC 100 press conference on Thursday, only to be persuaded back by UFC President Dana White. Brock is impatiently waiting to step into the Octagon. His intense training is over. Now all he has to do is wait.
That's a bit of problem. Brock hates to wait. It makes him angry. He gets this way before game day. He doesn't want to just sit around, or take in a show, or play a hand of Blackjack in the casino. Brock Lesnar wants to fight.
More specifically, Brock Lesnar wants to fight Frank Mir. And just to be totally accurate in my statement, Brock Lesnar wants to beat Frank Mir. As a matter of fact, Brock doesn't just want to beat Frank, he has a deep-seeded insatiable need to come out the victor on Saturday night.
