Top 5 and it's not a question. Where specifically he ranks, that's an open question. Wanderlei's PRIDE run was epic, but Chuck's time as a top dog in the UFC was pretty damn impressive, too, especially considering before he was champ he was knocking off the best the division had to offer while Tito was refusing to fight him. It also matters if we're talking about resume or skill, i.e. his career wins and accomplishments versus how he stacks up prime versus prime against the best guys in the division's history. Either way, if you don't think that he's near the top of the list then you just don't know what it was like to experience the era of The Iceman.
