Celtics sign Mr. Fourth Quarter Jason Terry

Multiple sources reporting that the Celtics have signed Jason Terry. Love this signing. Terry can create his own shot and embraces coming off the bench. The Celtics offered Ray Allen twice as much as the Heat, so if Ray leaves that's not on Boston. The door is still open for Ray to return, but regardless adding Terry is a huge move. Welcome to Boston Jason, aka Jet, aka Mr. Fourth Quarter.
