Perk+ PJ3 or the 29th pick for the TPE and we have a deal.
Why for OKC? Well, they stop paying 9M to a player that's the shell of his former self. 2009 Perk was better than today's Asik, at least on offense (so you get how terribad is Asik, really). OKC is cheap, they'd love to save all that money. Giving up PJ3 or the 29th pick would be worth for them.
Why for BOS? Perk will be an asset at the trade deadline (Theo Ratliff 2.0), ,and PJ3 or the pick would be a nice piece to add to use in future trades. Celtics would overpay Perk until July or until February, but in a year, Perk could be adding some value.
Being patient will be key for the Cs. Hopefully Danny is aiming at Marc Gasol / LaMarcus Aldridge in February 2015.
Go Celtics!
