I've been saying this for years.  Also, I don't know why they call it "mixed martial arts" when it's almost exclusively BJJ.  It was origionally called Mixed Martial Arts because they would have athletes with different fighting styles (ie judo vs taekwondo, karate vs muai Thai, etc) fighting each other. Whatever, it doesn't really matter. The point is, like you said, a fat guy in a Tapout shirt probably isn't an athlete.
