"While the Celtics did retain the right to match any contract offer to Glen Davis through the qualifying offer, Ainge said the injury status of Leon Powe - who had reconstructive left knee surgery after tearing his ACL in the playoff series vs. the Bulls - was a determining factor in the decision.
Ainge said Powe has been rehabbing with the team’s medical staff and will continue to have access to the staff, if he chooses, despite no longer being with the team. Ainge said he believed Powe was planning to continue his rehab in California." Scott Souza
I understand the risk of not signing a guy that has had knee problems, and isn't going to be able to play a game before the All-Star break, however, Leon is a risk I would be willing to take. If we had Leon for the Magic series, I guarantee we would have won. Even though he is undersized, he plays a lot bigger than he is. But it looks like it is the end of the Hard Work Leon Powe era in Boston.
