I would deal Calderon
for a mid- to late-first round pick and an expiring contract. If the pick is late in the first round, then another prospect should be included.
I don't see LA trading both first-round picks to land Calderon. They may deal one along with a contract (to make the salaries work) and a young player, but both draft picks likely won't be in play.
I think Portland is a good fit with Felton and their first-round pick for Calderon. I know people want the Raps to acquire Batum, but I don't see that happening unless Toronto sends DD, Kleiza, or Johnson in the deal. Plus, if I'm BC, I would be concerned about the possibility of Batum leaving Toronto once he hits FA.
