Yeah. Why he played only in the first half is beyond me. He was doing a good job of making Duncan work. Suns were rebounding very well with him in there. They held leads, damn it! D'Antoni has some great aspects, but, unfortunately, some even greater flaws, least of which is his GD pride that says, "If we can't win MY way, then the win isn't good enough."
That kind of logic doesn't belong in a team sport. Not from a coach. Not from a coach with this much talent and versatility on his roster. Maybe in college, but not in the pros. You have to win and do so when it counts and D'Antoni needs to man up, admit he's been bested and adjust. There's no shame in adjustments. The great coaches take pride in them.
He, and no other reason, is why I have almost zero confidense come playoff time. I know his hard head is going to ultimately sink the ship.
