Yeah; I've always like AB, but as others have said, the holes in his game probably mean that he's never going to be someone you build around. So I'd be open to moving him or keeping him depending on how things play out over the next year. If he's needed to obtain a star I a trade, by all means trade him. We have Smart, likely at least another guard in the draft, plus Rozier, Hunter, and Young (not to mention the possibility of keeping Turner who can also play the 2).
But if we were to say sign KD, Bradley is the perfect type of role player to play on a contender as he even proved early in his career with the Big Three.
