I liked the idea of this one, granted the Pacers / Knicks rivalry/history likely prevents this from going through. But the pieces seemed to fit.

Knicks shuffle the decks in a big way, add some additional playmaking and a stretch 5 who should play off Randle & Robinson in a good way while not sacrificing defense

Pacers gather bad contracts, draft picks, and young controllable assets (Robinson being the wild card, but he's worth the risk if they can get him to go the Jarrett Allen route).

Cavs address their wing situation and add another valuable piece in the rotation. Barrett can start or be the first guy off the bench depending on who their playing and raises their ceiling from a hosting a 1st round series to making it to the 2nd round.
