Given that Morey has been considering trading away Asik and Lin (those combined 30M next season might of might not have something to do with that, right?), and after last season trade petitions, I'd do this:
http://espn.go.com/nba/tradeMachine?tradeId=od8pwhtBOS in: Asik+Motiejunas from HOU, Stoudamire from NYK
BOS out: Lee+2015 LAC pick to HOU, Bass+Wallace to NYK, Humphries to PHI
PHI in: Humphries from BOS, Shumpert from NYK, a first rounder from HOU
PHI out: Thaddeus Young to HOU
NYK in: Wallace+Bass from BOS, Lin from HOU
NYK out: Stoudamire to BOS, Shumpert to PHI, Felton+2018 first rounder to HOU
HOU in: Young from PHI, Lee+2015 LAC pick from BOS, Felton+2018 NYK pick from NYK
HOU out: Asik+Motiejunas to BOS, Lin to NYK, first round pick to PHI
Why for HOU: get rid of the balloon payment next season. Get a good PF in Young, a good backup SG in Lee, and a good (at his prize tag) PG in Felton, who needs a fresh start and is a capable player at only 3.6M a year. All three have 3-year contracts, but the Rockets want to win now. Getting young deserves a first rounder going to the Sixers, maybe this year's, maybe 2015... it depends on Hinkie and Morey.
Why for NYK: get Lin back. Send away 3 players who are questioned by NY fans and media, get 3 character guys. Wallace is on a terrible contract, but he'd set a good example in that disfunctional locker. Bass is a solid two-way player, a professional. Lin is a fan favorite, brings some positive press to the Knicks, and it's worth the future pick to the Rockets.
Why for PHI: Get some salary floor and a good veteran guy in Humphries, a young prospect on little money in Shumpert, and a Rockets pick that will be a late first, but a good player can be had there. The Sixers could end up winning the trade if they can pick someone like McAdoo or McGary.
Why for BOS: Clear the books now and in the future. Get TurkPerk and Motiejunas as future building blocks/trade pieces and a Ratliff 2.0 contract in Stoudamire
Rondo/Crawford/Pressey
Bradley/Crawford/Brooks
Green/Bogans/
Sully/Kelly/Motiejunas
Asik/Fav/(Stat)
with 2.3M additional cap space to fill the two roster spots in case Bogans (or Crawesome) isn't traded before the deadline. Better flexibility, a little worse team = tanking powers clicking at full throttle.
