Leandro Barbosa, whose best days are well behind him, is headed to Beantown. Reports the Boston Globe: “Guard Leandro Barbosa has reached a one-year deal with the Celtics, a league source confirms. The 29-year-old Barbosa will figure into Boston’s backcourt mix in a reserve role. Barbosa averaged 11.1 points per game with Toronto and Indiana last season. Known as a scorer, he could find a role as Rajon Rondo’s backup, sharing time with Jason Terry and Courtney Lee. With Avery Bradley out until at least December, the Celtics seem to have a need for Barbosa, though he’s unlikely to play substantial minutes.”
