He may be a great coach and even a great person but there's just something about the guy I don't care much for. I can't really put my finger on it either.
Frustration.
Every coach or system has an Achilles heel. I watch their defense and cannot help to think its specifically designed to counter the motion offense. I’m not a coach, but I have to think that a well-executed high-post would cause them fits. They flank the screener and jump the screen trapping the ball handler and cutting off passing lanes on the apex. If the screener would drop back to the foul line, wait for the post defenders to come up, and pass to a cutting player on the baseline it would cause them to back off their aggressiveness at the top of the key.
