Celtics shop Rondo, Allen - NBA - Yahoo! Sports The Boston Celtics appear willing to make major roster changes to balance a chance for a championship run and future financial flexibility. The Celtics offered Ray Allen and Rajon Rondo to the Detroit Pistons for a package that included Richard Hamilton, Tayshaun Prince and Rodney Stuckey, league sources told Yahoo! Sports. Boston general manager Danny Ainge and Detroitâ€™s Joe Dumars never spoke, but rather the Celtics had a lower-level executive make the pitch to a Pistons official over the past weekend, league sources said. Detroit immediately rejected the idea, and it never advanced to the two top executives speaking about particulars. Sounds like Danny is on a mission.
