I agree completely.
Other than that I have no interest in reviving the old arguments on this thread about social class and all that rubbish. I will say that all the great coaches I've ever known where really smart guys. Not necessarily educated, intellectual, or upper class, ...but just really smart. And there's truth in the old axiom, "Don't just train hard, train smart". This applies to every sport and MA I know, not just WC.
