BOSTON — The Celtics entered the playoffs expecting to get everyone's best shot.
The East's top seed barely survived a tough one to open the Eastern Conference finals.
Jayson Tatum scored 36 points, including 10 in overtime after Jaylen Brown's tying 3-pointer with 6.1 seconds remaining in regulation, and Boston rallied just in time for a 133-128 victory over the Indiana Pacers on Tuesday night.
Jrue Holiday added a season-high 28 points and Brown finished with 26.
''Welcome to the NBA playoffs. You've just got to manage your emotions. Anything can happen,'' Brown said of his tying 3. ''It's not over until the final buzzer sounds. ... It's not over until it's over. We found a way to win the game at the very end.''
It gave his team a new life and helped it hang on to home-court advantage with Game 2 set for Thursday in Boston.
But guarding against complacency was also on the mind of Tatum. The Celtics have lost Game 2 in each of their previous two series.
''It doesn't prove anything,'' Tatum said. ''We won a big-time game. The series is far from over.''
