Out of all the trade scenarios for Melo.. the Bulls seem to be the most plausible (PJ did business with them before)
#1 Jimmy Butler is their star player who is inked long term
#2 Dwayne Wade (Melo's buddy) is not opting out of his contract bc he's not getting that $ elsewhere.
#3 Melo came close to signing with the Bulls when he was a free agent. Chicago gives him another big market (Jordan brand) and he'll make more money with his trade kicker.
In return for Rondo (non-guarantee contract bought out) Valentine & #16 would seem like a no-brainer for the Bulls & Melo... hence why I'd like another asset.
