On this day in 1966, Boston Celtics head coach Red Auerbach retired after taking the Celtics their ninth championship with a 95-93 victory over the Los Angeles Lakers in Game 7 of the NBA Finals.
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.
It is also the anniversary of Boston setting an NBA single-game playoff scoring record after beating the New York Knicks 157-128 in Game 2 of the first round of the 1990 Eastern Conference Playoffs.
The Celtics shot .670 (63-of-94 from the field overall), also a playoff record at that time. Kevin McHale led Boston with 31 points and 10 rebounds.
