Boston sends Bass+Lee to Houston
Boston gets Perk+PJ3+Dallas 2014 first rounder from OKC, future 2nd rounder from Houston
Houston sends Asik to OKC, future 2nd rounder to Boston
Houston gets Bass+Lee from Boston, rights to Abrines from OKC
OKC sends Perk+PJ3+Dallas pick to Boston, Abrines rights to Houston
OKC gets Asik
Not giving a young player of pick to get Asik/help Morey out of his "genius backloaded contract" trap.
Houston gets rid of Asik's 15M next season, gets the best player in the trade in Bass, a capable guard on an ugly contract in Lee, and the shiny draft rights to Abrines. That's worth a future 2nd in the 50s.
OKC gets rid of Perk's terrible (worst in the trade, maybe in the whole NBA) contract, gets Asik (healthy Perk) and only gives up Abrines' rights, PJ3 and a Dallas pick that may be in the 20s.
Boston takes on Perk's terrible contract, but he's a fan favorite, gets PJ3 and Dallas pick, plus a late second rounder that could be useful to get the next Colton Iverson. And cut almost 2M in salaries.
Houston and OKC get better this year, Boston gets worse but can take this step backwards because it will pay off as soon as 2015.
