That would be too much for a PG, Smart needs to start.
How about this?
JG to Memphis with Lil' Phil
Jordan Adams + Javale McGee to the Cs
Tayshaun Prince to the Nuggets
http://espn.go.com/nba/tradeMachine?tradeId=nvz4sxuWhy for Memphis: upgrade SF position, basically (JG+VC+TA+CL at the wings should be good), get a third string PG for cheap.
Why for Nuggets: save lots of money by getting under the tax, make room for Mozgov/Nurkic
Why for Cs: getting a rim protector to pair with Sully/KO, who could be both a long term contributor and a tank boost this season. Getting another prospect in Adams,
This would punt cap space into 2016, with Javale+Wallace combined 20M in the books until then, and maybe becoming good/great trade assets in a year.
Turner/Smart/Jameer
Bradley/Thornton/Adams
Crowder/Wallace/Young
KO/Sully/Bass
McGee/Zeller/Wright
This might not last a lot, as Bass/Wright/Thornton/Jameer could be very soon traded for more assets.
