I've only seen a little practice clips. It's good to just see him on the floor. I actually think he's going to struggle mightily for the bulk of this season. He has to physically and mentally adjust to the rigors of NBA game midway through the season. He's going to need to develop some chemistry with everyone else also. We really can't expect much from him.
He's 1-3 so far but he has looked solid so far. He's playing great defense and doing nice intangibles like tipping the ball out when he can't get a rebound.
From what I've seen of him, he really hasn't played all that bad. D'Antoni can do some good things for that kid.
