My bigger concern with him is that he doesn't look quite like a point guard, nor quite like a shooting guard.
I think that matters less and less in most NBA offenses, Stevens being one of them. I see comparisons to Lillard for Rozier (of course on the high end) and I feel the same way about Lillard (but he's just very good so who cares what position he really is). But if you were to ask me, I have not seen much from him passing wise.
I think he is a great athlete and showed flashes in many areas (handles, defense, shooting, slashing). Hopefully in his second year he starts to find his spots and moves and starts to contribute consistently.
Assuming he is still here of course. But I like him quite a bit.
