I would say quite a few if the scenario is taking any of them in their prime and transplanting today.
Coleman and Kerr, with today's training would be monsters now as they were then. Hell, I would say most of them except Tank would be incredibly competitive today.
Igor, Pedro, Bas, who today hits as hard or is as skilled on their feet today than these guys.
Arlovski looked damn good at one time even by todays standard, if it werent for the chin he could still be good.
If Anderson Silva didnt exist Vitor would have a good chance of being mw champion.
And the Shogun that beat Lyoto can beat any 205er. There is a clear lightness to his feet that he had in the first Lyoto fight that he doesnt have anymore, its pretty obvious that his knee is messed up...Im a Machida fan .
