So, reading between the lines slightly, he claims to be as good of an instructor as an Olympic Medalist and coah in Judo, and a legit black belt in BJJ.
I think we invite him to the site. His background is sketchy, and a lot of the younger guys in the class who didnt know any better were buying into it. Only a matter of time before he pops up teaching somewhere else. The sad thing is, a lot of kids in the class thought they were good. Everyone single one of them would get smashed at the other grappling schools in the area.
