I think it may be a catch weight, Gracie is like 6'1 and weighs 180-190, he's bigger than Hughes obviously with him being 5'9 170. Royce really needs to lose this fight, since he quit competing in UFC before mma evolved. People still believe you can take Gracie Jujitsu and still defeat any opponent anywhere anytime. Jujitsu isn't the only tool and if you study Pride Fighting, it's clearly not the most dominant. The people who seem to be ruling mixed martial arts at the moment are strikers with great takedown defenses like Vanderlei Silva, Quinton Jackson, Chuck Liddell, Tim Sylvia, Mirko Crocop, Fedor Emalienko (of course Fedor is a fuckin submission magician but still, he prefers striking). Theres a reason Bas Rutten and Frank Shamrock challenged Rickson Gracie and never got a reply. Rickson knows his 400-0 record wouldn't stay intact - probably why he never fought Kazushi Sakuraba either
