I'm sure he is legit on the mats and I don't know him personally. He also beat Marcelo Garcia which is fucking incredible. But, it is kinda weird that he is willing to fake an accent. That makes it seem like he is trying to be a part of a club. When he talks about the importance of the gi, it makes me feel like he has a dog in the race (i.e. fitting in with the people who's accent he is faking). Obviously I don't know him personally but I think it is a good instinct to use circumstantial evidence of a persons level of bias when he is presumed to have authority (i.e. because he is an accomplished competitor). It certainly doesn't mean you can't learn from him. I really value people who are able to speak the truth, regardless of outside influences. When somebody seems willing to drink somebody else's kool-aid, it kind makes me proceed cautiously.
