Jefferson for Hamilton and the rights to Brandon Knight. Harris for Calderon and the right to swap picks. And I don't love Hamilton, but that's the price you pay to effectively buy another lottery pick that should've been drafted earlier. Calderon starts but Knight has the chance to compete for the starting job, Calderon is about as pure a PG as it gets and offers a nice contrast to Knight's game while he refines those skills (conceivably under the mentoring of Calderon). Finally, Calderon's game will age well, and I think if Knight becomes a nice starter, you can keep Calderon to once again be the best backup in the league (which would also serve to marginalize Calderon's decreasing defensive ability).
/silly, silly pipe dream.
