I would consider this trade if there was another trade Danny thought he could make that could really put Boston on the next level as this trade alone isn't good enough to make Boston a real contender. Not sure what that trade would be of course, but at least a team like below would be a solid playoff team.
PG - Rondo, Bayless, Pressey
SG - Afflalo, Stauskas/Young/Harris (or some other rookie wing from #12)
SF - Green, Wallace
PF - Sullinger, Olynyk, Bass
C - Vucevic, Humphries, Anthony
I don't think you re-sign Bradley in that situation, but bringing back both Humphries and Bayless makes sense. Maybe Pierce signs as a free agent to add some nastiness to the bench, but even then the team is still lacking the real go to scorer that is needed to be a real contender.
I think it is a trade Boston would consider, thought I'm not sure Orlando would even offer it as they like Afflalo and Vucevic.
