i pretty much agree w/ everyone in saying that Mir needs the win more than Lesnar.
I also think that the UFC needs Lesnar to win more than Brock needs a win in the UFC. Like Harlem said, Lesnar has plenty of time to prove himself and not many would be too shocked if he lost his first fight in the Octagon. If Lesnar wins teh UFC will have one of the biggest hyped fighters in a long time. Just more money to put in Dana and theFertitta's pocket if Brock can win this one.
