I read that yesterday also, and I give JD high marks for having the right attitude. That said, JD said that he blames the metrics for making him look like a bad defender. My response to that was, it's not the metrics that are making him look bad, it's his bad defense that are making him look bad.
Obviously, I'm pulling for the guy both offensively and defensively. It's possible that he can play with improved defense going forward. But to date, he has been very bad.
