"I have been doing stand-up [fighting] since I was 4 years old," said Mir at the UFC 92 post fight press conference. "The issue was conditioning. Before, I would walk into the Octagon afraid of getting tired. Tonight it could have gone 10 rounds and I would not lose in any position."

Brock Lesnar however, has a different take on Mir's "improved stand-up.

"Mir's stand-up only looked better because Nogueira didn't show up," UFC heavyweight champion Brock Lesnar told ESPN.com.

Lesnar, who had been rooting for Mir to win so that he could get a rematch with the man to hand him his only MMA loss, talked about his reaction to the fight.

"My first thought was 'Nog looked like crap,'" Lesnar said. "My second was, 'Yes, a rematch! Payback time.' My Christmas wish has come true."
