i think that the point that most of u are missing is that being a great martial artist isnt the same as being a great fighter,a good example is nick rodriguez in grappling(the guy that beat rockhold for those who only follow mma),he has been doing jiu jitsu for less than 5 years and he is beating a bunch of black belts,does that mean that he knows more jiu jitsu than them ou ir more qualified to teach?no,what it means is that he is Strong,young,in his prime,knows what Works better,has a bunch of tricks,probably some very recente new ones and is more active than this old black belts.am i saying that mike perry is nick rodriguez?no,but it is the same concept,if you want someone to teach you martial arts,probably Michael jai White would be a better option,but to think that in a street fight mike wouldnt win is crazy,he is faster,stronger,is way more active in real fights,probably has taken more shots and knows how to deal with them,has a better gas tank and has more experience in open fights like that(all martial arts allowed),mike would beat the living shit out of Michael jai white
