gusto -laqueus - I'd be curious to see what Mark Kerr has to say about that, given he was ADCC champ. BJJ can't have advanced that much in 10 years that what he accomplished is invalid.
kerr is really attribute based. consider the old gi players compared to an old kerr.
kerr was awesome in his prime, im not hating. but it wasnt due to superior technique. he had good technique, but he was bigger stronger and faster
It takes time to train attributes, so I don't consider that to be really invalid. Also, given that people say the gi lets you neutralize people with attributes it would make sense to go the attribute route in nogi. It's certainly quite effective in MMA.
