If the draft order goes as planned, Portland will get the Nets' pick at 6th and the Raptors will have the 7th. Portland and the Raptors can swap picks and trade Calderon to Portland and the Raptors get back Matthews and Babbit. This scenario seems much more probable than wising for Deron Williams to come to Portland.
Portland gets a serviceable pg, and still have a good pick with the 7th. With the 7th, Portland can pick Harrison Barnes and pick Perry Jones with the 11th.
