I think his 3-pt shooting is at the direction of Stevens, not really his own initiative. I'd rather he cut the volume he takes and stick to the paint --> one of the coaching points I don't agree with about Stevens.
I love how guys make excuses for him. He even shots them in the summer videos. Did CBS tell him to shoot .28% from their, I am guessing not. He takes them because he does not want to run the whole floor, I have seen Stevens shake his head at a few of Sully's threes. It is simply not a good shot for him, the team, until he can make them. Practice them now in summer, not when your being paid to make them. He shoots them because he is lazy, doesn't have to run the floor. People loved comparing him to Love, but he is no Kevin Love and the main similarity is he can rebound and can't D just like Love.
I just hate him shooting them at the end of games too. He shot us out of a few games last year trying to be the man. Stevens said he wants him to develop the shot. But I hardly think he green lights him, otherwise he would not have jerked him out on some of the misses.
As for the impact, shooting percentage is a big part of being a big. Sully has great hands but he is of dubious height, I doubt he is 6-9 sometimes and he can't jump. He relies on bumping his man and uses his body to score. One area though that he has definite impact, that it is ignored is on the boards. I dislike his game, think he is lazy and squanders his talent but he is one, if not the best, rebounder on our team. His D is poor and he is no rim protector. But you have to acknowledge his prowess on the boards is better than KO, and Zeller and the other guys.
That being said, I hope we deal him. I think he is fool's gold. His ceiling is low with his poor athletic base. He is a good rebounder and I would wager he probably is one of the best offensive rebounder when not out of position trying to be Kyle Korver.
