The roster is looking good, there is talent at every position and 3-4 major starts on the roster. However, I see a GLARING hole on the bench. It's that hyrbrid 3-4 guy that can guard the mobile/perimeter forwards in the league. Sure Pierce can cover one, for stretches, but I really feel that the roster is lacking that perimeter defender who can guard the hybrid forwards that teams seem to be going towards. I think Orlando's Lewis/Hedo were match-up nightmares last year and I can see teams attempting the same thing again this year.

With that said....

I think the obvious way  to improve is to consolidate talent. Why not re-visit last year's deadline deal that flopped and targer Andres Nocioni. He's the PERFECT fit to finish of th bench. He'll come cheaply in that all it would cost are some expirings like Scalabrine, Allen and a small contract filler like Walker, Giddens or Hudson. His deal declines each year and he's battle tested. He'll hit the open three at a positive 40+% clip and is the prefect role player to come off the bench for this roster as he's an active defender that can guard both 3's and 4's. He's also insurance in case KG goes down. Not all the frontcourt depth would be lost. I think this is trade that makes sense both ways, as it helps the Celts win the championship now and helps the Kings to continue rebuilding.
