Organization: UFC

Record: 20-5

Reason: How many guys in the world can lay legitimate claim to being historically the best Heavyweight ever? Fedor? Big Nog? Cain? Want to know the connecting thread between those three – they all have been beaten by Werdum. In his fight with Cain (a fight I thought he would get mauled in), he showed a huge improvement in striking that had him put a beating on Cain unlike anyone before. Fabricio Werdum is no longer the one-dimensional Jiu-Jitsu guy he was early in his career and he is now possibly the best Heavyweight mixed martial artist ever.
