WCS would help Sully a lot because of his defensive range. He also can score without the ball and is not a guy who is going to be a huge post up threat. But surround him with shooters, he will get second shot opportunities. He can also run so if we ever go with a running time he can fill the lanes.
I do not think he fits CBS offense that well because he likes bigs who can spread the floor with their shooting but Sully does poorly in that regard as well.
