Forget about these big time players, most unlikely it would happen. I would target

ATL - T-Mac
BOS - Jeff Green
CHA - Gerald Hendersen
DAL - Vince Carter (vet minimum if the Mavericks get sweep by the Thunder)
DEN - Wilson Chandler
GSW - Dorrel Wright (if they pick Perry Jones III or Harrison Barnes)
MIN - Derrick Williams (Trade)
MIL - Brandon Jennings
NJN - Deron Williams
NYK - Jeremy Lin
ORL - Ryan Andersen (straight up for Amir Johnson)
PHI - Louis Williams
PORT - Nicholas Batum
SAC - Tyreke Evans
SAS - Tony Parker + Kawahi Leonard (most likely not)
UTAH - Burks + AK47
