I honestly don't see the C's moving Rondo at this point - sure, they're shopping him hard but that doesn't mean they'd give him away. With all of the talk swirling about his difficulty, what could they really get for him? The biggest mistake Danny Ainge could make would be to settle on a deal for Rondo and get a bunch of mediocrity back.
If I were a GM (which I'm definitely not, lol) I'd hold on to Rondo for the rest of the season, try to get the Beasley deal done and see how those two work on the court for the rest of this season. Then revisit Rondo trade scenarios + Beas sign-and-trades in the offseason should disaster ensue. Rondo really hasn't had an opportunity with a young, athletic scorer and I'm DYING to see what he could do before we give up on him.
