Just to be clear on my own nominations, the question was about upside comps not likely ones. There is absolutely no question that DJ and Dumars are best-case projections that I'd be shocked for Bradley to approach, ever.
Guys like Hill seem like highly realistic ones---he's not that far from Hill today (better on-ball defense, not as good a ballhandler, similar 3pt shooting but weaker mid-range) and is still only 23. He may never improve at all, but it's not hard to project him to be George Hill right now.
His skillset is funky for comps---some of the defense-first guys near his size are really true PGs (cheeks, snow, van lier) which just isn't Bradley's skillset. Others his size who played off the ball a lot (vinnie johnson, lou williams for example) have totally different skillsets.
On hops, I don't think he lacks them...but I don't think he has DJ's either. Young DJ likely could outjump Gerald Green. Thus, for me, DJ's 6-4 was materially 'larger' than Bradley's size. Anyway, that's why I noted it...agree Bradley can jump.
