To me,Pride will always be the best. Period.
I'm not sure if I can pick one greatest moment though perhaps I may give it to Crocop and Fedor. I believe that was truley the first MMA superfight in the heavy weight division. No one thought it would happen after Fedor broke his hand. They kept saying he was ducking CC,the high kick was going to kill him,etc. Then what do you know? Not only does Fedor eat the kick,he delivers one of his own! Classic example of how Fedor fights his opponents fight and demoralizes them in the process.
Saku vs Newton was an amazing fight. When it comes to straight grappling,that fight is probably still the best MMA fight in my opinion. Or when Rampage was talking on his cellphone before fighting Wandy as the national anthem played. That was great. Bas,Semmy Schilit,and Rampage talking about getting their mojo.
Rickson growing concerend as Saku dispatched Royler.
Coleman going out of control after losing to Fedor.
Heath Herring and Nog having an epic fight.
Rampage saying f*$*k the UFC.
Dana losing what hair he had left as Rampage manhandled Chuck in what was probably the best MMA event of all time.
Frye vs Takiyama. Pure guts!
Damnit,why did it have to end?
