Shinya Aoki is very technical. And i am not discovering nothing new if i say that is so good in Bjj :-). But is true that the level of almost all the other guys is a bit poor to be in a 'panam'.
Have you seen the technique he uses for the Achilles ankle lock submission? if he catch the right leg of the other guy, he passes his right arm under this leg and TAKE his own gi in stead of using his left arm too for the clasic technique (he uses his left arm to take left arm gi of the othe guy to prevent defending the submission).
