The Celtics have agreed to sign Jason Terry from the Dallas Mavericks. How is this not GREAT for Boston? Terry is alot like Ray Allen from the 3pt but joining Terry along side Allen and Paul Pierce makes Boston a 3 pt machine team. Jason Terry is coming off another season as a Sixth Man with the Dallas Mavericks. Averaging about 14 points. It was rumored the Miami Heat was interested in Terry and also interested in Ray Allen.
