Royce Gracie was not even ranked high in the Gracie family at the time when he dominated in the UFC.
Its pretty funny how easy it is for someone who knows ground fighting to own someone who doesnt. And you are right about belts Emerald Red, if I wanted to get a black belt then I picked the wrong martial art. People at my gym get their blue belt in a minimum of 1 and half years. On my first day I got submitted twice in 5 mins by a 5f10 65kg girl (and I am 6f4 90kg and sporty) who was a white belt.
And no its not that fun having your carotid artery blocked by a woman squeezing you in between her legs (triangle choke).
