James Posey's agent Mark Bartelstien confirmed today that his client is not going to exercise a $3.2 million option and will officially become an unrestricted free agent.
Free agency begins Tuesday. Players can sign with new teams starting on July 8. Posey is expected to get a lot of interest from a lot of teams, but will also be the Celtics' top priority.
The Celtics are trying to decide today whether or not to make a qualifying offer to guard Tony Allen. If the Celtics decline to give him an offer, he becomes an unrestricted free agent.
