IT and Crowder.
Or
IT and a Nets pick.
Basically get an All star back + a sweeter for their top 10 player that is not going to resign.
I was thinking IT bradley & a nets pick. IMO that still leaves BOS with a 2 seed in the east lineup. As you said before with IT they get back an all star which is the direction I think they want to go in. Not only that but OKC already has a VERY good & YOUNG lineup already in place. A lineup that last year (with two stars) was the second best team in the west. This way OKC has the ability to flip the nets pick with Oladipo for a star with a lineup of IT AB (insert) Adams and Kanter in place.
Then next year we can sign hayward & have a lineup of Smart, Westbrook, Hayward, Crowder, Horford. Which imo is a pretty lethal offense/defense lineup.
