If the pick is top 3 and within the next 3 years, yes I would trade AB in a heart beat. Shabazz Muhammad, Nerlens Noel, Jabari Parker, Julis Randle (maybe), Andrew Wiggins and Jahlil Okafor (maybe) are most likely barring a major setback, going to be NBA all-stars. With a few (Wiggins, Noel, Parker) being franchise cornerstones.
AB is not going to land an unprotected pick from a bottom 3 team. But IF the opprotunity presents its self, you got to trade Bradley. I can not believe one person on this board wouldnt trade Bradley in this situation.
