Pritchard missed his first long bomb, a pull-up in transition over Jalen Brunson. A few possessions later, he found himself wide open after coming off a pair of screens. He was well behind the 3-point line, but he let it fly and gave Boston a 32-16 lead late in the first quarter.

Jayson Tatum scored 22 and had his best game of the series. The Knicks need to find a way not to trail by 20 in Game 4.

The Celtics’ win was a complete team effort and also an example of the team’s guile and ability to respond, even when the circumstances are dire.
