"It is not every day that you can add a player of Shaquille's caliber to your team," said Danny Ainge, Celtics President of Basketball Operations. "His past experience speaks for itself and we believe that he is a great fit for our roster.""I am honored to be joining the Celtics," said O'Neal. "I have played against Paul, Ray, Kevin, Rajon, and Jermaine for many years and it will be great to be able to call them my teammates. I cannot wait to get to Boston to get started in pursuit of another championship."
UPDATE: The Globe's Gary Washburn is reporting it is a two-year deal worth $2.8 million.
