The Celtics were in the mud with their missed 3-pointers as the playoff stage exacerbated their shortcomings in the Game 1 loss to the Knicks.

Ahead of the Boston Celtics' second-round series against the New York Knicks, all Joe Mazzulla wanted to talk about was the margins. The Celtics were heavily favored and had beaten the Knicks four times in the regular season, but their coach stressed that none of their advantages matter if they don't take care of the details.

The Celtics were undone by the weapon that had crushed the Knicks in the regular season — the three-point shot. They shot 15-for-60 from beyond the arc and Brown and Jayson Tatum were held to 23 points each. Kristaps Porzingis was scoreless in the first half and didn’t return, sidelined by illness.
