I would not trade any of our top 5, but if we can get Turner for some combination of RW, Langford, Edwards, Kanter/Theis, picks, I would do it.
If they are moving him , it's to save money since they don't need him with Sabonis playing extremely well. The Pacers could get some good prospects on cost controlled deals, and some valuable draft picks. I can't see other teams offering a better set of assets for Turner.
The question for Ainge would be , do you use the Memphis pick to trade for Turner? That pick could potentially land a star prospect.
