Al Attles, a Hall of Famer who coached the 1975 NBA champion Warriors and dedicated over six decades to the organization as a player, general manager, and, most recently, team ambassador, has passed away. He was 87.

The Warriors announced on Wednesday that Attles passed away at his home in the San Francisco Bay Area on Tuesday, surrounded by his family.

Nicknamed "The Destroyer" for his aggressive playing style, the Warriors were his passion and only team after they drafted him in the fifth round in 1960. This marks the longest tenure with a single franchise for any individual in league history. The 6-foot guard averaged 8.9 points, 3.5 assists, and 3.5 rebounds in 711 games with the Warriors over 11 seasons, and his No. 16 jersey was retired by the franchise.

Attles, one of the first Black head coaches in the NBA, witnessed some of the most memorable moments in basketball history across different eras. He played in Wilt Chamberlain's historic 100-point game for the Philadelphia Warriors in Hershey, Pennsylvania, on March 2, 1962. Attles made all eight of his field goal attempts for 17 points.

He also coached Hall of Famer Rick Barry the day he scored 64 points against Portland on March 26, 1974, and watched Klay Thompson achieve a remarkable 60 points over three quarters in December 2016.

Attles served as the Warriors' coach from 1970 to 1983, guiding them to the 1975 NBA championship with a decisive four-game sweep of the Washington Bullets. He later took on the role of general manager for three seasons and held various positions in the front office, including vice president and consultant.

"Alvin's impact on the game of basketball and the Bay Area community is undeniable, but his legacy as a family man and humanitarian shines even brighter," the Warriors stated. "We join his wife, Wilhelmina, son Alvin, and all who knew and loved him in mourning his passing."

Attles was inducted into the Naismith Memorial Basketball Hall of Fame as part of the 2019 class. He had previously received the John R. Bunn Lifetime Achievement Award from the Hall of Fame in 2014.

"Many historic, successful organizations have one player who becomes synonymous with the team," Warriors coach Steve Kerr remarked. "Al Attles is that figure for us. He represents the Warriors for numerous generations of fans. We are fortunate to have him."
