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 Knicks came from 20 points down to force overtime and beat the Celtics, who had a terrible night from 3-point land, in Game 1 of their series.

The Celtics blew a golden opportunity to go up 1-0 in the series vs the Knicks. Instead, they are down 0-1 and have lost home-court advantage.
