Good for him. The Celtics might have lost Ray Allen, but they have gotten some serious depth in the SG position right now. Avery Bradley, Jason Terry, and Leandro Barbosa at the SG position is pretty deep. I wish him the best as a Celtic...Leandro Barbosa has agreed to a one-year deal with the Boston Celtics. Barbosa finished the 11-12 NBA season with the Indiana Pacers following a trade from the Raptors.
