I like Avery but he is nowhere near Dumars game
Not now, but that's probably the level he can perform at if he maximizes his potential. Bradley still has upside.
AB will never get to Dumars level. Dumars was a top-notch swing guard. excellent defender, very good ballhandler, very good passer, terrific shooter, respected lockerroom leader. (horrible GM though but that's beside the point).
AB's as good a defender but the rest just isn't happening. I'd be thrilled if he could improve to the point where he wasn't a TO waiting to happen on offense when handling/passing the ball but Dumars was a polished player in that respect.
I don't really have a handy player comparison for AB. Definitely not Dumars but I think he can be better than Bowen. He's as good a defender already and is more than just a 3 and D guy. Maybe Michael Cooper but smaller and a better shot.
