My idea:
Houston: Brandon Bass and Evan Turner
Bos: Omer Asik
Philly: D. Montiejunas, V. Faverani and 2015 LAC first rounder from Boston
Celtics get the rim protector they want without giving up anybody in the long-term plans (also by including Fav, they stay below the luxury). Also allows Sully to play the PF position.
Philly gets a couple young guys, immediately helps them land a higher pick and they get the first rounder they wanted for Evan Turner.
Houston suddenly has a really good backup wing and pf to help and contend and has gotten rid of two players who have asked to be traded.
Win, win, win...right. Maybe?
