I get that. You misunderstand me.
My point was that someone may have asserted that Hewitt had an expertise in "Building a Motion Offense"--he published a DVD with that title. Yet based on his results during his last years, I would dispute that expertise. So, if it's said that Eric developed an expertise but the evidence of its implementation for his team was decreased winning, I would question its value. As a stats guy, I don't just accept assertions of expertise as inherently valuable. I have to see evidence of their value. So, I'm not passing judgment one way or the other.
Still, my comment was not intended as that big of a point. It was more about my agnosticism than about him. I'm happy that he's got a positive reputation and look forward optimistically to his contribution to GT basketball.
