There's plenty of other players on the team I rather trade than SAR, but b/c of his great contract, has probably more trade value than most players on the team. Other than KMartin and Artest, SAR is probably the most coveted player on the team b/c of his production to salary ratio. All things being equal, I rather keep SAR and trade K9. But if the Bucks offer up Magloire, I'd be more than happy to ship SAR to Milwaukee.
Don't know if K9 is unmovable, there's plenty of contracts out there that are much worse that we can trade for. But as far as getting something of value , Petrie would seriously have to work his magic. But stranger things have happened tho. btw, I won't say Corliss' contract is the worse than K9's, in fact plenty of teams want expiring deals. Combining K9 and Corlis might actually net us a big man like Ratlif or Adonal Foyle. Neither of which are great players, but both can back-up the center position.
