ugh theres a reason why Pride is extinct man. Out of all those names you mentioned, Rampage was the only one to do shit in UFC. With all that great talent you think the league could have produced more than one short-lived UFC champ. You talk about them like they're some of the best fighters in the world when really they were only the best fighters in a lesser organization. Beating Lidell is no longer impressive.
Of course the cage limits the way people can move, thats the whole point, its a fucking fight not a game of tag. The cage plays a part in almost every fight, how often did someone actually fall out of the ring in Pride
