im going to have agree with ivan fights can go anyway. you take the top 10 fighters in the world and make them fight every month each other, thiers going to be different outcomes every single time, just because one "beats" another in a match, doesnt neccesarly mean that individual is "tougher". yes probabaly 99 out of 100 matches dorian would probably lose, but that one that win out of 100 he could get could be the first fight out of all 100 just a lucky strike obviously he has KO power, when his oppenent isnt expecting it.
I remeber seeing vitor belfort beat the shit out of vanderli silva in UFC 44 second KO win, i thought belfort was the man and that silva just plain sucked at first, then I see belfort losing to sakuraba, and see silva beating sakuraba 2x in a row, first time with ease... point is really a fight can go any way.
