Remember that we would need to match outgoing salary (125% plus $100K) if we are signing Hayward. If the trade took place after the draft, you could include the draft pick's salary. You would be looking at at least Bradley, the pick, and filler. That filler may include somebody like Rozier and Jackson, but more likely somebody like Smart.
I still think a Bradley, Crowder, 2018 Cs pick (not BKN pick) would be a good deal for Chicago. I would hate to give up Bradley, Crowder, and this year's BKN pick (or Brown)...like, I would be pretty furious.
