Celtics Surrender 20-Point Lead, Lose Game 1 to Knicks

The Boston Celtics lost Game 1 of their Eastern Conference semifinal against the New York Knicks in overtime, despite holding a 20-point lead earlier in the game. Boston set an NBA playoff record by attempting 60 three-pointers, but only made 15, with Jayson Tatum and Jaylen Brown struggling from beyond the arc. Head coach Joe Mazzulla defended the team's shot selection, stating that while there were a handful of shots they could improve, he was generally satisfied with their process and shot quality. Mazzulla also cited defensive lapses—leaving Knicks shooters open and allowing transition points—as key factors in the Knicks' comeback. Late-game decisions, particularly around timeouts, drew scrutiny, though Mazzulla explained he was trying to capitalize on his team’s speed and blamed some confusion on the referees. The Celtics' depth was further challenged by the loss of Kristaps Porzingis to illness and Sam Hauser to injury, casting uncertainty on their availability for Game 2.
