The reasonable target is probably going to be a player who is seen as too old to keep around for a team that has decided to go through a rebuilding process.
I think that sounds right.
So who's probably on that list?
Tyson Chandler (rapid decline, yucky contract)
Omer Asik (not very good, horrid contract)
Zach Randolph (might not even be available, but could be worth pursuing)
Marcin Gortat (if the Wizz give up on the playoffs, could be available; not a terrible contract but he'll be a 3rd stringer by the end of it)
Rudy Gay (questionable if the Kings would really consider moving him, and not sure a guy who passes so little would make sense on the C's)
Kevin Martin (could help the team with shooting, but how much of an upgrade would he be over Turner / Bradley / Smart?)
Nikola Pekovic (who knows if he can still stay healthy and play at a high level? also seems like a duplicate of David Lee's skillset without the passing)
Danilo Gallinari (my guess is the Nuggets would ask for a ransom for him; they've never seemed willing to all-out tank and he's their best player)
Lou Williams (do you want two undersized gunners in the rotation? Would take time away from Smart and definitively block Rozier for a while)
Roy Hibbert (he's not helping the Celts on offense, where they struggle)
Chris Kaman (can he still play? Would he really help the Celts? Maybe as a bench scorer)
Trevor Ariza (might be available if Rockets are willing to punt this disappointing season, is trending toward washed up but would still help the Celts)
