The Rondo trade rumors are out there.
I think he'd be a good fit here, and I think BC would be wise to see what it would take to get him.
I'd offer something like Calderon
+ Ed Davis and see if I could get a counter offer, though I'm thinking that Boston would want our first round pick in 2012 thrown in.
If the pick is in the 5-10 range, as projected, it could be worth it. It might even be a good idea to trade the pick before the lottery (before it likely gets devalued...) That's just playing the odds, though - that strategy could backfire.
