Suns should package Dunleavy + Pack (cb) + whatever other assets they may have for someone like Stephen Jackson. I'm not entirely sure that Mason/Dunleavy's defense ever reaches B+/A- level and I think they'll be able to find plenty of scoring from ZBo, Mason, Calderon, and Jackson moving forward. ZBo/Mason/Calderon's defense will always be somewhat suspect I think. DRob won't be there forever. They need at least one long term upper tier defender for playoff matchups. DRob can handle the front court for a least a few years but they've got nobody other than 2ppg Battier to match up in the backcourt.
