I think Ainge always values talent above need and position, and he and Brad don't value bigs much at all.
IMO, if he signs Kemba, he's going to get a middle of the pack big and roll with him. There probably won't be a deal that is going to make any sense with Brown/Hayward/Smart going out in trade. We're probably going to sign the Frenchman that was discussed the other day, maybe keep Theis (or not), and add someone like Kanter. Think about it. He had a bushel of picks the other night, and didn't draft anyone taller than 6'7. RW is the only player he's drafted in the 1st round taller than 6'8 (other than Zizic) in several years. The Celtics just don't value Centers, I would assume excepting a superstar like AD.
