I would do the Orlando deal. We trade Young and Sullinger for the #5, and Wallace for Frye and Gordon, taking on cap space from Orlando. We draft Cauley-Stein with the #5 and trade up to Charlotte at the #9 with whatever they want and draft SF Johnson. Starting lineup - Smart, Bradley, Stanley Johnson, Olynk, Cauley-Stein, with bench - IT, Gordon, Crowder, Frye/Jerebko, Zeller. Decent playoff team now, possibly great team with more first round picks still coming to us in the future.
But I can't imagine Orlando thinks this is a good deal. Maybe Sacramento would, but they are crazy.
