If Boston goes all in (so to speak) then I think Gordon would be a reasonable target that probably won't cost that much.
Boston - Kevin Love, Eric Gordon, Omer Asik
New Orleans - Gerald Wallace, Jordan Crawford, 2016 Boston 1st
Houston - Bass, Bogans, 2015 Clippers 1st, 2015 Boston 2nd
Minnesota - Humphries, Sullinger, 2014 Boston 1st, 2014 Brooklyn 1st
(the picks can be modified somewhat i.e. maybe give Minnesota one of the future Brooklyn picks and keep one of the 2014 picks as an example)
Boston thus goes all in this year with the following post-trade lineup
PG - Rondo, Bayless, Pressey
SG - Gordon, Bradley, Brooks
SF - Green, ?
PF - Love, Olynyk
C - Asik, Faverani
A little light at SF, but I'd take my chances with that lineup against team in the league as long as they are relatively healthy come playoff time.
