Just going from a historical standpoint here...
Fedor gets eliminated early due to an elbow TKO.
Wanderlei replaces him and beats Brock Lesnar by knees.
Wanderlei is then KO'd by Henderson, who is then KO'd by Shogun.
Machida beats Thiago Silva by KO (I'm going to say, maybe late round 1?), Shogun then beats Machida in a close decision.
Mousasi then procedes to KO Shogun and submit Silva, both while laying on his backside to win the tournament.
TOURNAMENT WINNER: Mousasi.
LOL ~ Hey, I said NO INJURIES!!! he he...I just realized I called Gegard, Gerard...oooops.
