Among Auerbach's accomplishments during his 20-year professional coaching career were eleven Eastern Division titles (including nine in a row from 1957–65), 11 appearances in the finals (including ten in a row from 1957–66), and nine NBA championships. With a total of 16 NBA championship rings in a span of 29 years (1957–86) as the Celtics coach, general manager, and team president, Auerbach is the most successful team official in NBA history. He is credited with creating several generations of championship Boston Celtics teams, including the first Celtics dynasty with Bill Russell, which won an NBA record eight titles in a row (1959–66). As Celtics general manager, he created championship-winning teams around Hall-of-Famers Dave Cowens in the 1970s and Larry Bird in the 1980s.
