Uhhh...does this guy also realize Machida is BJJ black belt?, and ur arguement doesn't make sense, because its MMA, Machida doesnt only use Karate and BJ doesnt only use BJJ...plus seriously, Machida fights 205 lb rite now...BJ penn is currently fighting at 155...and he has barely been able to finish any of his fights using just karate...but he did finish off Sokudjou using his grappling
ooohhh and also was that sweep a determing factor in the fight?...No
