The nutshell version:
Boston Celtics trade: Pierce, KG, Ray, Powe, Rondo, Perk, Pruitt, Walker, BBD
Boston Celtics receive: Blount, Curry, Kmart, QRich, Jeffries, Haslem (we needed his salary; he can play), Atkins, Cook, Joel Anthony
It kills us both in terms of talent *and* the salary cap, and improves two Eastern Conference rivals (one in our division).
