How about this 3 team trade?
Boston - Turner, Asik
Philly - Humphries, Bradley, Philly pick
Houston - Hawes
Boston gets a better defensive player in the post with a more certain contract and gets a better offensive finisher with more size. Philly gets a better fit in Bradley, a pick, and still keeps the flexibility. Houston swaps out Asik for a much better offensive fit in Hawes who is pretty talented and expiring.
Seems like a trade that might work for all 3 teams. Not sure Philly gets enough value nor if Houston would value Hawes enough for that to be the only thing they would want for Asik.
