I think we could use a starting caliber SF and can somewhat convince myself that maybe a change of scenery can do him good.
Our same roster plus Melo at the 3 (if we trade only cap-space for him) would at least get more respect around the league and I think could also bring better results. As I said, starting SF is maybe our weakest position.
He could actualy be more available than Rudy Gay right now and I think now could be the time to buy low in his case. "Buy low" is kind of our colture this summer isn't it? maybe trading for Melo isn't that bad idea?
