The think I'm most worried about, actually, is how poorly both are shooting. Both should be, if nothing else, excellent shooters who know how to pick their spot.
I think they're both capable shooters, but neither is really an isolation or volume scorer. They should each be taking a handful of jumpers a game, but most of their attempts should come near the basket.
Unfortunately, the complete lack of high level offensive options on the team right now, not to mention ball-handlers who command the attention of the defense, means the shot distribution for Sully and KO are less than ideal.
I expect both players to be a lot more effective once the roster is a bit more balanced and they can play roles that fit their skillset.
