For me, it was Hendo koing Fedor. Anderson getting koed comes to mind by Weidman, and Crocop getting RHK by Gonzaga also, but who really saw Henderson koing Fedor? Anderson was getting beat up on the ground by getting taken down in a few seconds after the first round begun, and started to clown around like he does sometimes when he faces dangerous grappler, for example Maia and Leites, and then got ktfo when he had his hands down like he was Ali reincarnate, which he clearly is not. Crocop had to suffer the one of the most unjust stand up calls in the history of MMA that I have ever seen, and just could not see the kick coming to his dome. Gonzaga is known to gas and quit in late rounds and his heart is rather questionable, given how his career really drizzled off from that point, who knows what would've happened if Herb Dean did not have a brain meltdown and did not stand them up People are going to talk about how Henderson has this dynamite in his hands and all, but I do not believe Henderson hits any harder than some of guys Fedor had to face like Hunt,Shilts and etc. Henderson was knocked down to the ground by Fedor combination, and somehow reversed the position and landed the punch which momentarily seemingly knocked Fedor out a little. I have NEVER seen anyone koing ANYBODY from that position like that, Henderson hasn't done it before and would EVER do it again. I don't know how many MMA fights have taken place since UFC 1 or even NHB fights, but out of all that fights, have you seen ANYONE getting knocked out like that? Fluke ko of the century, the title goes to Dan ' Decision Dan' Henderson.
