Here's a variation that OKC and NO couldn't pull of alone. Note that depending on the S&T values there may be some filler needed.
BOS: Chris Paul, Emeka Okafor
NO: Russell Westbrook, Jeff Green (S&T), Jermaine O'Neil (expiring), Clippers #1 pick via Celtics
OKC: Rajon Rondo, Glen Davis (S&T)
Why for Boston? Unbelievable starting 5. Paul, Allen, Pierce, Garnett, Okafor. Upgrades both offensively and defensively. Bring back West, Bradley, the 2 rookies, and work with MLE + amnesty candidates.
Why for NO? 3 young players (Westbrook, Green, draft pick) plus real cap help for a team w/o an owner. If they moved Ariza (or used amnesty) and let West come off the books they could be in play for 2 max free agents and/or the Dwight Howard sweepstakes, which would surely entice a new owner.
Why for OKC? End the power struggle around Westbrook and the uncertainty around overpaying on his next contract, which would probably be at least $5M/year higher than Rondo's deal. Build around Rondo, Harden, Durant, Ibaka, Perkins, with Harden taking a bigger chunk of the backcourt scoring and Rondo as a true distributor. Davis as a 6th man.
