In the Jujitsu or any martial arts world, it is a disgrace for anyone to come off as a fraud and say that they are black belts when in fact they are not. In order to train students you have to at least have a brown belt and up. So you will have those who will say they are black belts so that they can open up a school and train students. This is dangerous being that these students could learn wrong techniques which in turn could get them killed in a situation which would require for them to apply a martial arts defensive attack. If a fake Jujitsu practitioner was teaching Jujitsu to James Toney when he fought Randy Couture with the fakester bragging that he has a black belt under all the Gracies, and Toney performed the way he did, than everybody would be mad. Edmund is a clown who could had gotten Rousey killed. He lacks the knowledge to help Rousey become a much more effective striker as far as defense is concern while not also teaching her how to properly set up punches to get into clinches. Rousey does not throw any feints or jabs or even push kicks. She just tries to run into a clinch by trying to hug her opponents like Barnie the Dinosaur while her chin is sticking out and while she is lacking head movements. Rousey should take Mayweather's offer to train her or she could simply go join an actual legit MMA camp that trains champions since they usually have good boxing coaches to help her out better.
