The UFC Heavyweight Champ talks to the Las Vegas Sun about his UFC 106 opponent and number one contender in the division, Shane Carwin:

"[Shane Carwin's] a tough guy. He's undefeated, but some of the guys he's beaten aren't worthy of having on your record. He hasn't fought anybody. He's fought (Gabriel) Gonzaga, so I really think he's 1-0. He's a tough guy and a wrestler. But he's a Division II national champion -- enough said. I don't know what he is, 11-0, 10-0, but he'll have a loss against Brock Lesnar."
