I can easily see Rondo being moved for the right price. I know I said this earlier about Westbrook, but I can see Boston going after Paul by dangling Rondo out there.
Yeah, Rondo's a good player (great?) but if you can add a Paul and still get something out of KG, you could conceivably extend KG's career.
Wouldn't surprise me to see them move Jeff Green either. See if there's a team willing to buy into his youth.
