Take it for whatever it's worth, but Adrian Wojnarowski is reporting that Rondo and Ray were offered to the Pistons :
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 Detroit’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.
If true, I understand the Celtics motivation, in that they'd be getting back two all-stars and a developing point guard for Ray and Rondo. However, I have my doubts about Stuckey, especially when compared to the upside of Rondo. If there's any truth to this rumor, we may be lucky that Detroit turned it down.
Update: Kelly Dwyer examines this deal from Detroit's perspective, and says that they're fools to turn it down.
