Jo Jo White, the sharpshooting guard for the Boston Celtics whose smooth, nearly unstoppable jump shot helped carry the team to two National Basketball Association championships in the 1970s, died on Tuesday. He was 71.

His death was announced by the Celtics, who did not say where or how he died. White received a diagnosis of brain cancer in 2010. White’s daughter Meka White told ESPN that the cause was complications of dementia, noting that he had developed pneumonia.

During his 10 years in Boston, White, who was inducted into the Basketball Hall of Fame, embodied the tradition, pride and excellence associated with the Celtics. On the court, White could do it all. With quick hands and quick feet, he jump-started fast breaks, finding teammates with clever passes or taking matters into his own hands with a deadeye jump shot.

“He was a champion and a gentleman; supremely talented and brilliant on the court, and endlessly gracious off of it,” the Celtics, for whom White worked as the director of special projects, said in a statement on Tuesday.
