Great minds and all that, Gainesville, I was killing 15 minutes on the ESPN trade machine yesterday, and came up with the exact same scenario, under a few assumptions -
1) Wallace's contract isn't as attractive as any of the half dozen straight salary dumps currently available. Too many teams either have huge trade exceptions or cap room.
2) Meaning the front office likely has to target veterans with either unwieldy contracts, MLE signings that are a year or two longer than is prudent and the ilk, or injury concerns - i.e., players that aren't going to be attractive to the younger Knicks and Nets or the now re-tooling Cavaliers and Raptors.
3) Ainge will be looking to bring in either a rotation caliber PF/C or a wing defender - or both.
I would be more interested in using Sheed's contract to acquire Songaila and Julian Wright.
New Orleans was another team I took a hard look at. Although I decided upon James Posey and the draft rights to Quincy Pondexter. I like either package less than Foster and Jones.
