The Greatest MMA Fighters Of All Time

Each person has your preference. It's a source of endless debate, but who are the greatest MMA fighters of all time?

my list:
Royce Gracie
Fedor Emelianenko
Mirko Cro Cop
Anderson Silva
Wanderlei Silva
Antonio Nogueira
Lyoto Machida
José Aldo
Maurício Shogun
Vitor Belfort

Fedor Emelianenko is by far the best, other don't know

I struggle with putting Royce Gracie on a list like that. He's undeniably a pioneer and a legend in the sport, but one of the best actual fighters? He's not even really an MMA fighter, most of his legacy dates back to the time when they were all specialists representing their particular code. Outside of that era he's got more draws resulting from whacky rules stipulations than he does legit wins over actual competition (LOL Akebono and Shamrock nutshots).

Georges St Pierre and Matt Hughes are probably the two names I'd say are missing. Maybe BJ Penn too (I can't stand him but there's a case to be made).

There's some current fighters who I strongly suspect will end up on that list in the future too: Jon Jones, Dominick Cruz and Mighty Mouse among them.

Professional MMA has been around for what, 3 weeks or so, bit early for best of all time. How about best so far.
