you probably have to give up 2016 and 2018 brooklyn picks and an additional 1st(out of C's 2015 and Dal pick) plus a prospect for a shot at Cousins
Something like
Bos sends: KO,Turner and Thorton's salary, 2015 c's pick, 2016brk , 2018 brooklyn
Sac sends: Cousin
You probably have to do it , but those could be some very good picks.
Then you have AB,Young,Sully, zellar , dal pick, cle pick, 2017 right to swap with brk as chips to land , Rondo TPE to land Lawson
Bos sends: Rondo TPE , Brk 2017 pick, cle pick , 2 philly 2nd rd picks (which are like late 1sts)
Den sends: Lawson
We would have no brooklyn picks left
PG: Lawson / Smart
SG: AB / Young
SF: Prince / Crowder
PF: Sully / Bass
C: Cousins / Zellar
In the east this team is easily top 5
