I noticed Mayhem said he was a BJJ blackbelt. I always thought he had a great ground game. But never knew who taught him. Anyone know who gave him his black belt? 
Raphael Cordeiro.
In Jiu Jitsu? He is a muay Thai coach. I dont believe he teaches BJJ
Also I think mayhem just started training with him for stand up and mma
Werdum
I think Raphael Cordeiro got his black belt from Cristiano Marcello, who is from Gracie Humaita. He was the BJJ coach for Chute Boxe for a long time.
Joao Assis or Werdum.
mmanthebay - Joao Assis or Werdum.
this, but I think it was Assis, it happened the day he threw diaz's camera guy out of the gym.

No that's not it.
Pretty sure it was Joe Moreira. In fact, I'm positive it was Joe Moreira that gave Mayhem his black Belt.
Nevermind... confused
I can't tell if you guys are trolling. It was definitely cordiero
Cordeiro gave him a black belt in muay thai(it's a chute boxe) thing.
Gotta love Mayhem, what a crazy fun guy.
he came from Georgia to OC as a Jacare Purple Belt, over 10yrs ago. He tore through people, was very good at Gi BJJ. Rafiel promted him to BJJ Black Belt, not Muay Thai
