Another name I thought of:
-- Drew Gooden
Not always the best defender during his career, but he seems like the kind of guy who would benefit playing next to KG.
Jason Thompson aint going anywhere...and the rest of those guys are still significant dropoffs from what KG is, which is what we have now anyway.
I'm not sure what you mean by the latter part of this.
Of course all of these guys are significant dropoffs from KG. I never meant to suggest that any of these players would replace KG. Rather, the idea, I would think, is to get a player who can play alongside KG for limited minutes, but more importantly somebody who can step into KG's role when KG is on the bench and do at least a credible job of protecting the paint and getting some points inside. The Celtics desperately need a player like that. I don't agree with you when you say that we already have that.
As for Jason Thompson's availability, I have to disagree. He's a nice player, but he hasn't shown anything so far in his career to make him untouchable. The Kings aren't in a position to consider any players "untouchable" other than Demarcus Cousins. They need to open up some playing time for their lottery pick Thomas Robinson anyway, and they are pretty weak on the wings.
I don't think a trade for JT is out of the question, though it may be a long shot. Probably less so than a trade for Gortat or Josh Smith, though, which is the point of this.
