After reading replies from the Murilo thread I remember that in older days, BJJ black belts were also able to fight under Vale Tudo rules (not even MMA! Vale Tudo), that was like the average ability one should have in order to be accepted as a BJJ blackbelt. Now you see Black Belt that cant hold themselves under MMA rules with BJJ alone training. Of course the quality of fighters are increased but BJJ'ers nowadays dont know the least aspects that their old counterparts used to know, like closing distance, good takedowns, punch blocking and those things. I think the reason for this is the environment were BJJ moved to, and that is from Brasil to America, the change of place led also a change of students market, on Brasil you have economical middle class people with the Gracies but mostly the ones training with Carlson and other BJJ trainers were the ones with not too much money or a good job (Im not laughing about them, here is normal to see those situations) so they see BJJ like a WAY to go to Vale Tudo and fight. This plus the "Im the strongest fighter" way of thiking, make BJJ'ers also Vale tudo fighters. This radically changed when BJJ go to America were people training were middle class but with lifes insured financially (a job, a family, other goals in life other than fighting) and just trained to be good on the art, not even thinking about Vale Tudo or MMA, just pure BJJ, why? because they didnt have the need to fight, just have fun, loss weight or make new friends... totally different from the goals of people in Brasil about the use of BJJ. Im not saying this is bad but this is the real answer why MOST (not all) modern BJJ'ers cant be anymore fighters with enough knowledge to defend themselves on the cage with BJJ only.
