I think this is a problem largely with the kung-fu community and mindset and not the art itself. For whatever reason (perhaps better penetration of MMA into Japan and thus Japanese martial arts) Karate, Tae Kwon Do, and Judo seem to have made much more successful transitions into MMA- each of those arts has representative fighters in the higher echelons of MMA. Not so much Kung Fu.
As a Kung Fu guy. I agree with him.
