Jalen Brunson has found his shot in the fourth quarter of each game of this Eastern Conference semifinal series. But he has struggled in the first three periods.

The New York Knicks have been exceptional in the playoffs so far, defeating the Detroit Pistons in six grueling games before taking two road games at TD Garden against the Boston Celtics. Fans aren’t just witnessing what history might one day call a legendary team — they’re seeing something even more special.

The Knicks trailed by 20 points in the second half of both Games 1 and 2. They came back to win Game 1 in overtime. They won Game 2 by one point in regulation, and Jalen Brunson hit the game-winning free throws before Mikal Bridges sealed the victory by stripping Jayson Tatum on the Celtics' final possession.
