What went wrong for the Boston Celtics vs. the New York Knicks in the 2025 NBA Eastern Conference Semifinals? The Celtics fell in six games to the Knicks after a litany of injuries to Jayson Tatum, Jaylen Brown,

There was plenty of blame to spread around for the Celtics, but the biggest factors were poor 3-point shooting in Games 1 and 2 (Tatum), sloppy ball-handing that led to turnovers (Brown), poor end-of-game strategy (Mazzulla) and an inability to contain Brunson at key moments (Holiday).

The New York Knicks pulled off a stunning upset when they dethroned the Boston Celtics as NBA champions by defeating them 4-2 in their best-of-seven second-round playoff series. New York sealed Boston's fate by winning the first two games on the road at the TD Garden and then clinched the series win with a fourth win at the Maddison Square Garden.
