He's not effective coming off screens or off his own dribble. If he's allowed to set, and catch, he's better - which is likely true for most 3 point shooters. That's why I'd like to see him more spot up, get a kick out from the post or on a skip pass. There are times when he's in that position and I think he should shoot, but he passes on that shot, and will then take the more difficult 3 pointer that comes off of movement. It's like golf, the farther the ball travels, even the most fractional off balance/off center release, will carry farther off line the farther it goes - while it may fall on a 10 footer, it's far enough off line on a 22 footer to not go in.
With Uthoff and Jok coming in next year, unless he becomes more of a threat to make his 3, I think he'll see less time on the floor next season. Hopefully my prediction is wrong, which means he got better.
