I think if you consider Crawford part of your new core group, you have to find ways to start paying these guys. That means shedding unwanted salaries using the nets/hawks pick and the clippers pick. We don't need to spend the money to pay someone that is drafted in the back half of the first round just to be the 10th or 11th man.
Core group - rondo, Crawford , AB, Green, Sullinger. Bench -- olynyk, vitor.
Trade Wallace and humphries for stoudamire. Use the nets/hAwks pick and try to get Shump if you feel he can be good 6th man.
Trade Lee/Bass/Clippers pick for Okafor. His contract comes up so u can afford to pay AB and Crawford.
That leaves you with 8 guys in the rotation. Brooks or Bogans would ideally be dumped on the Knicks. In the draft, go for a power forward that is good enough to compete with Olynyk for PF minutes. 9 man rotation, all young guys, Pressey is the 10th man. Green and Eondo are the oldest in the group.
