On this day in Boston Celtics history, legendary head coach Red Auerbach retired after taking the Celtics to their ninth championship with a 95-93 victory over the Los Angeles Lakers in Game 7 of the 1966 NBA Finals the day prior.
Auerbach coached Boston for all nine of its championships up to that point — eight of them consecutive between 1959-66 — before passing the baton to player-coach Bill Russell. His 16 seasons as head coach produced a 795-397 regular-season record (a .667 winning percentage) and a 90-58 postseason record (.608), the winningest in league history to that point, a record that would hold for many years.
Auerbach would remain with the team in an executive capacity until his death in 2006.
