Short answers, pulled from the story.
Red Auerbach won a combined 16 NBA titles with the Boston Celtics across his career as coach and executive. As head coach alone, he led the Celtics to eight consecutive championships between 1959 and 1966, the longest championship streak in North American professional sports history.
Red Auerbach retired from coaching in 1966 holding an NBA coaching record of 938 wins. His career coaching record was 938 wins and 479 losses across stints with the Washington Capitols, Tri-Cities Blackhawks, and Boston Celtics.
Red Auerbach drafted Chuck Cooper with the Celtics' second-round pick in the 1950 NBA draft, making Cooper the first Black player ever drafted into the NBA. The pick effectively broke the color barrier in professional basketball.
Red Auerbach appointed Bill Russell as head coach for the 1966-67 NBA season, making Russell the first African-American head coach in the four major North American professional team sports. Russell went on to win two additional titles in 1968 and 1969 as a player-coach.
In 1980, Auerbach convinced the Golden State Warriors to trade him the third overall pick and center Robert Parish in exchange for the first and thirteenth overall picks. With the third pick, Auerbach selected Kevin McHale. The resulting Parish-McHale-Bird frontcourt became one of the greatest in NBA history.
Red Auerbach was inducted into the Basketball Hall of Fame in 1969. In 1980, the Professional Basketball Writers Association of America voted him the greatest coach in NBA history, and that same year he was named NBA Executive of the Year.
