He's been around the league for a long time and even won 6th man of the year back in 06-07. But if you need an update on what Barbosa brings these days, here's a quick refresher.
He provided Indiana with limited scoring punch in the postseason (5.7 points per game), but the potential still is there on a Boston team that desperately craves bench scoring, even after an offseason aimed at stockpiling bench scorers. Barbosa can create his own offense out of isolation or spot-up opportunities utilizing his speed (though his transition numbers last season won't wow you for a blazer). The defensive side is the bigger concern given that he's undersized, but his speed makes him an adequate defender who should benefit from being on a defensive-minded team like Boston.
The last two years have not been as kind, however. He was limited by a wrist injury in 2009-10 and then traded to Toronto, where he had more injury problems that affected his shooting, as well as his overall game. Barbosa was then traded again, this time at the deadline to the Pacers, where he saw action in 22 games and struggled in the playoffs, particularly against the Heat. Barbosa did open some eyes with a strong performance during the Olympics when he averaged 16 points and shot 40 percent from 3-point range for Brazil, and while his days as a change-of-pace sixth man may very well be behind him, he’ll be joining a Celtics team that simply needs backcourt depth.
