Green had his good moments but, IMO, he had too many iffy moments for a player whose main focus should be not making mistakes. I think Green gets in trouble sometimes when he wants to make a play instead of taking what is given.
Off the top of my head, such plays include: 1) When he failed to box out Parsons and then overreacted and fouled Lowry. That was especially bad and deserving of the immediate hook because Neal made the same mistake in the first half. 2) I haven't watched the replay but there's no excuse for getting stuck under a pick and leaving Lowry wide open for three when the Spurs had a chance to put it away in regulation. Unless the tape shows something that made it 100% unavoidable, Green deserves blame for that. 3) When he didn't retreat to the right area in transition defense and then ended up having to foul Dragic in the fourth.
One of his first half three-pointers was almost a no-look shot. He caught the ball, looked to pass for a split second and then shot it. Not surprisingly, it was an airball. Another three he seemed to force it after not being ready to shoot when he caught it. And, if I'm remembering correctly, that one two-pointer he made was a throw-it-at-the-basket-and-hopes-it-goes-in shot.
I do agree that "bad shots" was a poor way to describe those shots though. They weren't bad shots as in he shouldn't have shot them ... it was more about the execution of the shots.
