Al Attles, who spent more than six decades serving as a player, coach, general manager and team ambassador for the Golden State Warriors, has died of undisclosed causes, his family has announced. He was 87 years old.

Attles was drafted by the Warriors back in 1960, when the team was still in Philadelphia. Nicknamed “The Destroyer,” he played for 11 seasons before the team retired his jersey and made him one of the first Black coaches in the NBA.

During his 13-year stint as head coach, he scored 557 victories – the most by a single coach in franchise history – and led the team to win the 1975 NBA championship. He stayed on with the team as its general manager for three years and then took roles as the Warriors’ vice president, consultant and team ambassador, the team reveals.

“Alvin leaves behind a profound legacy within the game of basketball and the Bay Area community, but especially as a family man and humanitarian,” reads a statement issued by the Warriors. “We mourn his loss alongside his wife, Wilhelmina, son Alvin, and all who knew and loved him.”
