The Boston Celtics missed a golden opportunity to go up 1-0 to a team they've handled pretty early over the year: the New York Knicks. After being up by as many as 20 points in the third quarter, the Knicks crawled and scratched their way back to complete the Game 1 comeback.

It took overtime and Celtics star big man Kristaps Porzingis missing the entire second half for the Knicks to win. Nonetheless, a win is a win. The Celtics are now down 0-1 in this best-of-seven series.

Boston did not have their finest Game 1, especially in the second half. In a game where they should have cruised to victory, they blew it in dramatic fashion. NBA fans on social media had some fun with the Celtics and their stunning meltdown.

Lakers and NBA legend Magic Johnson provided his two cents on the epic Game 1 between Boston and New York.

NBA fans continued on X with a mixture of shock and poking fun at the Celtics.

Celtics fans had every reason to be caught off guard by the team’s off night from beyond the arc.

Boston has been one of the league’s top perimeter shooting squads all season long, averaging a league-best 17.8 made three-pointers per game. Their volume is just as impressive, launching an NBA-high 48.5 attempts per contest—a major part of their offensive identity.

However, that was not the case on Monday night.
