Shane Carwin tops the list, with an undefeated record of 12-0 and a shot at Brock Lesnar for the undisputed UFC heavyweight title at UFC 116.
While the punching power of Carwin is well known, he has won seven of his 12 fights via knockout, perhaps something that gets overlooked is his wrestling and submission skills.
Carwin has won five of his fights via submission, and before becoming an MMA star, he was a two-time NCAA Division II Wrestling National Runner-Up and the NCAA II Wrestling Heavyweight National Champion in 1999.
Carwin also likes to work fast. None of the big heavyweight's fights have gone beyond the first round.
His most recent win came against Frank Mir at UFC 111 via TKO due to some devastating punches. The win earned Carwin the interim UFC heavyweight title.
Not only is the undisputed title on the line, it is widely believed that with Fedor Emelinaneko's recent loss, the winner of the Carwin vs. Lesnar fight would catapult to the top of the MMA world heavyweight rankings.
