i think to many peoples think that it is the style that do the job but it is not like that! IT IS THE MAN BEHIND IT!! you think that if the gracies won some fights(i think they were many ) their style is perfect?? this is like sayig that all aikidoka have all the abillities of The great O-sensei or that all kiokushin karateka will go mad in a corrida and kill all the bulls as MasOyama and the examples may continue . But all this guys have something in comun : they all trained and some are still training hard, very hard - O-sensey was known for perfecting a single tehnique for years , the great Kimura of judo was known for perfecting his unbeatable o-soto-gari against trees, masOyama for killing bulls(this is a bit controversy) and crushing stones with his bare hands and the examples may continue . So i think that saying : if you want to beat a bjj you must learn bjj is wrong . As the bjj is learning how to get u to the ground u can lern how to kick him hard or pivote around him as he makes his move.
