If the Jazz want assets, they can get some from Philly and Cleveland.
Jazz would trade out Jefferson and Miles.
Jazz get Jamison (exp), Nocioni (exp), Philly 1st, Miami 2013 first (via Cleveland)
Cleveland gets Jefferson and Philly gets Miles.
Alternatively, Jazz can switch Cleveland with Charlotte
Jazz trade same players and switch Jamison with Maggette, and get Portland's 2013 first round pick (top12 protected through 2016, where it's unprotected).
Charlotte gets Jefferson in this scenario. Better draft pick, but have to deal with an extra year of Maggette, instead of getting two expiring contracts.
Of course, this all would have to be accepted by all three teams.
