I really think there is something to the Rondo for Cousins framework of a deal. I just am not a fan of the specifics of this one. I particularly am not a Jason Thompson fan, hate to give up Lee, and don't think Isiah Thomas is a starting PG on a playoff team.
I think for a Rondo for Cousins deal to work (which is a very realistic possibility), it will have to either include Evans, who Danny may still love, Brooks (who I am not sold on, but perhaps Danny is??), or more likely, include a third team to send a starting quality PG to Boston. One name that comes to mind is Darren Collison.
