Look, the Pacers are NOT going to trade Ron to Miami, Cleveland, or any EC contender. The only option I could see would be Paul Pierce and I doubt Boston messes with that.
So moving west, there are so viable options out there and we'll go team by team.
Dallas: Not good trade fits here. Dallas probably doesn't trade Josh Howard, nor do Pacers take Stack or Marquis Daniels.
Denver: Would be interesting if Nene wasn't injured but at this point they aren't going to trade any of their assets.
Golden State: They have interesting pieces for the Pacers to ponder. A Pietrus + Dunleavy trade could work out well for the Pacers, as Pietrus is great in low minutes.
Houston: I know this is considered a possible hot spot involving T-Mac, but there's no chance that will happen, just from a financial view. Other than that they have no other pieces, besides Yao who isn't going anywhere.
LA Clippers: I doubt they would want to mess with success but a Maggette for Artest could be a good gamble of disgruntled, and injured players. Anything bigger would ripple too much into their success.
LA Lakers: Odom might be the most interesting name. If Phil wants a new look then he could make an Odom for Artest + filler trade. It's a gamble that Phil is used to taking (Rodman), and maybe he thinks he could correct Ron. If not then nothing else here.
Memphis: Hmm....Somehow I doubt the Grizz do Battier for Artest, definently not Gasol, and the Pacers aren't taking just Mike Miller. I don't see a trade working out here.
Minnesota: Wally for Artest is somethign I doubt the Pacers do. Wally looks good early on but is essentially a more whiny Mike Miller. Don't even try a KG trade, and nothing else makes sense either.
New Orleans/OK: Not a good fit either. Doubt Pacers do Mason for Artest, and the Hornets aren't trading JR Smith or Paul for him.
Phoenix: Not much here. Suns aren't trading Nash, Marion, Stoudmire, and Pacers aren't taking anything else back so no go.
Portland: Darius Miles is an interesting possibility and would be a good gauge of how much the Pacers wanted to dump Ron. Miles is also disgruntled and would be a gamble. Otherwise, not much to see here.
Sacramento: Peja for Ron will be the most hotely debated trade as it makes too much sense for both teams. The salaries match, Ron is Ron, Peja is struggling in Sacto, and the Kings will want to make a move and this could be the kind of gamble they want.
San Antonio: Next please.
Seattle: Not a good partner here. Sonics aren't trading Allen or Lewis and Pacers aren't taking anything else.
Utah: Interesting possibility of a Harpring for Artest trade, as Harp would be a nice fit on the Pacers, but I doubt Sloan touches Ron with a 40 foot pole.
