The deal I keep coming back to:
POR Gets: Prince, Lin, Carter
ATL Gets: Turner, Swanigan, Calderon, BEST of DET/POR 1sts*
DET Gets: Curry, WORSE of DET/POR 1sts*
*Lottery Protected - If Detroits pick is in the lottery, ATL receives Portlands 1st. If Portlands 1st is in the lottery, ATL receives Portlands 2020 1st.
Detroit will probably be the 7th or 8th seed in the West, so if you're Atlanta, you're talking about getting a top 5 pick (ATL) a pick between 7 and 12 (DAL) , and the 15th or 16th pick (DET).
Detroit would move down 4 to 8 spots (maybe less) to get their starting SG for the rest of the season. If they miss the playoffs, they essentially give up Calderon for Curry.
