The question isn't what would you give up, it is what would Portland want and therein lies the rub.
I think something like this would probably work for both teams
Aldridge, Matthews
for
Sullinger, Bradley, Brooks, Melo (if they want), Humphries, 2014 Brooklyn 1st (top 16 protected or something like that), 2015 Boston 1st (lottery protected)
Leaves Boston
PG - Rondo, Pressey
SG - Matthews, Lee, Crawford
SF - Green, Wallace, Bogans
PF - Aldridge, Bass, Randolph
C - Olynyk, Wilcox, Iverson
I'm sure Aldridge would play a fair amount at center to allow Wallace and Bass more time at PF to optimize the lineup with the better players. Not a title contender, but a good solid mid-range playoff team in the East that with one more move could jump into the upper echelon and is young enough to do so.
