On this day: IT goes for 53, Bill Russell hangs first banner as coach

On this day in 2017, Isaiah Thomas hung 53 points on the Wizards on his late sister’s birthday, and in 1968 Bill Russell won his first championship as a coach.

It is also the anniversary of a 109-99 Game 7 victory over the Chicago Bulls in the 2009 NBA Eastern Conference first round, the Celtics clinching the series with only the third game in that stretch that did not require an overtime to settle.

“Oh, my God. Overtime after overtime after overtime,” offered center Glen Davis on the welcome change of pace, via the Associated Press. Ray Allen led the Celtics with 23 points and 7 rebounds, and Paul Pierce added 20 points and 9 boards.
