A lot of what Dos said, but also, who's to say Ainge has to give up much of value? Or at least, value to the Celtics?
Danny seems to value cap space in 2015 extremely highly. So any contract that expires before then, gaining or sending, is almost inconsequential outside of a handful of players (Rondo, Sully, Olnyk, Green).
So really, it comes down to picks. Is Asik worth a lottery protected Celtics 1st? Maybe. A top-20 protected first? Almost certainly.
And what does Morey value? Smart money says immediate cap relief and future non-cap binding in 2014's summer assets (or picks).
I don't doubt that given enough motivation on Morey's part, a deal gets done. If Melo decides to go to Houston, which I really hope he does to redeem his sullied career, who's to say if Danny plays hardball we can't get Asik for non-guaranteed contracts and a 2nd?
