No need for Ainge to give Pierce an extension past Garnett's deal. They need to have the cap flexibility to make sure Rondo doesn't go through his prime years on mediocre teams, which Pierce did. And remember, it's more important to Pierce's legacy to remain a Celtic for life than it is for the Celtics to keep him for his entire career. No matter what happens, Pierce will be a HOFer and get his # retired at the Garden. But for him to be mentioned along with Bird, Russell, etc., he needs another ring and to finish his career as a Celtic.
