there's no denying that kron is one of the brightest stars in the grappling scene at them moment. all this time i thought that rickson was teaching all the secret invisible jiu jitsu moves. then i come to find out that he barely trains with his old man.
so who was most influential in making kron the grappler that he is today? is it henry akins, the man who was the lead instructor at the rickson academy when rickson left? is it jean jacque, who seems to corner him often? is it his cousins down in torrance? is it xande and the humaita team?
i know that most of the credit should go to kron himself but coaches are always important too. especially in a sport like BJJ.
I was gonna say kron but you already covered that haha 
I think all of those guys played a part they have all trained exclusively with Rickson too.
Im sure Rickson still had a huge influence because he put him on the right track even if it was only 100 classes lol.
