The only current real asset we have is Calderon. (not counting KP obviously)
But no one's trading anything worthwhile for Melo...and the rest of the roster is basically a dumpsterfire.
I still think a decent deal could be had for Melo... seeing as - as recently as 14 months ago he could have fetched Jimmy Butler and Mirotic. If he starts shooting better, that plus his improved effort on defense could make him appetizing to a fringe contender.
