Sadly, I could now see this taking place.
With both teams off to a horrible start, I could see a deal centered around swapping Rondo for Calderon.
I could also definitely see Jeff Green involved as either a 6th man, or starting at SF while Melo is out with his back issues (or for that matter, Green starting with Melo at the 4.)
As for players coming to Boston, I could see any combination of Calderon, Shumpert, Bargani and Amar'e.
Oh, and I can see Bass going to the Knicks as well.
