are bigger stronger guys graded differently than everybody else? most of the time these guys tap out higher ranks using unorthodox strength moves. it is not uncommon to see a 250 lbs. all muscle guy tap out a 150 lb. purple or brown belt even though they are not very technical at all they use the little they know to tap out higher ranks. now time and time i see these guys get promoted fast. well i guess what im trying to ask is that: are bigger stronger _______ belts less technical and know less than the same _______belts who are smaller? my take on it is that smaller guys are more technical than the bigger guys of the same belt level. so a rooster weight in the purple belt division is far more advanced (in terms of hip movement and overall bjj knowledge) than an ultra heavyweight in the purple belt division. even though the ultra heavyweight can tap out the rooster weight, the rooster is a true purple belt while the ultra heavyweight might very well be only a white belt or a blue belt technique wise.
