NAW is probably a bit under discussed when it comes to potential. I don't really believe in him, but he might have a better shot than THT.I think Justin Zanik acquired NAW thinking the Jazz could develop him into something. Hard to say if they still feel that way or not.
Butler's Summer League didn't make him look like he's really a floor general type. Maybe if the spacing is better and the players around him are better he could do it. He sure looks like a backup right now though. His best attribute appears to be floor spacing with some secondary creation.
THT and Bolmaro aren't exactly efficient offensively either, so it's not like they're just going to blow by guys on the roster. I see all four of those guys being in the same boat. Jazz will develop one or two of them probably and eventually dump the others.
