I'm OK with 3, AB, Rozier and JJ. Because team does need to shed some picks or young players. I would rather it be AB, 16, 23, JJ and Nets 2018 though. Then send 3, 2017 swap swap rights, AJ, Smart, Hunter to Kings for Cousins.
Sign KD and you have
IT, Butler, Crowder, KD, Cousin
Rozier, Young, Mickey, KO,
Use all second rounders on 4 year guys that can impact right away. Hammons, Brogdon, Finn-Smith, Warney, Utoff.
