This would be an off-season trade - Demar for Millsap (sign & trade). UTA needs a legit starting SG (Hayward and Foye are tweener type, bench guys) and Millsap is not staying to free up minutes for Favors. So the Jazz should be happy to not only get a starter back, but one who fills a need. It would be a straight up sign & trade + filler, depending on the Millsap offer sheet. Seems to fill a need on both sides.
