My final vote is to trade back with Charlotte or Utah, and let them absorb Drummonds contract while giving us future draft capital. Even if its just a few 2nds.
Draft Tre at 4 or 5
Resign Grimes at 16m ( i dont see Detroit or Brooklyn overpaying for him)
Resign Yabu with the available cap space from dumping drummond and drafting lower. Thats around 7.5m saved
Take all the 2nds we have and move up to get Beringer/Sorber/Flemming...whoever u can get
Maxey
Grimes
PG
Yabu
Biid
McCain
Tre
Edwards
Bona
Flemming
