Heavyweight: Mikro "Cro Cop" Filipovic
Light heavyweight: Chuck "The Iceman" Liddell
Middleweight: Rich "Ace" Franklin (I think he can regain the belt after losing some octagon rust, he trains like an animal).
Welterweight: Georges "Rush" St. Pierre
Lightweight: B.J. "The Prodigy" Penn if he decides to stay at this division. If not, then it will still be Sean "The Muscle Shark" Sherk.
