If the Celtics want to bottom out for the lottery then it's slightly possible. They could take NYC to town for future picks too- by future I mean the distant future lol.
I'd make NY take back Wallace's deal in return as well as it would give us essentially two less years of Wallace's contract because Amare can be terminated at the end of this year.
NY SENDS
Amare
Shumpert
Hardaway Jr
first round pick 2017
first round pick 2019
FOR
Rajon Rondo
Wallace
Courtney Lee
*We pay Amare for 1 season instead of Wallace for 3 seasons. Move Lee's deal too and make them absorb both Wallace+Lee.
*Hardaway and Shump are nice assets and the first round pick is probably 18-23 range.
*Amare's expiring (early termination option) means we would clear 25+ Million in one year, we'd also bottom out and guarantee a top 5 pick, with plenty of future picks from Brooklyn and New York.
*So yeah, essentially we'd guarantee a top 5 pick, with enough room to sign two max free agents and Jeff Green's excellent value contract.
Depends how badly the Celtics wanna tank.
Rondo could just walk to New York in 1.5 seasons anyway.
Personally I'd try and float Rondo else where and try and peel a top 10 pick whilst moving Wallace's contract before saying yes to this. You've got the rest of this season before the Knicks terminate Amare's deal anyway.
