Years: 1966–1969, 1973–1977, 1987–1988
Record and Accolades: 340-291 (.540 winning percentage), 2 NBA Championships (1968 & 1969 with the Celtics), became the first black head coach in 1966
Bill Russell's 11 rings as a player seem unreal by today's standards but two of his chips stand out among the rest. Before the 1966-67 season, Red Auerbach retired and appointed Bill Russell as the head coach of the Boston Celtics. With that historic decision, Russell became the first black coach in NBA history. The Celtics won two championships in Russell's three years as player-coach, making him the first black coach to win an NBA title. Fun fact: DJ Khaled's biggest hit was based on this dude's life.
