The Boston Celtics entered their Eastern Conference Semifinal against the New York Knicks as overwhelming favorites to advance. In each of the first two games of the series, the Celtics led by at least 20. Both of those contests were in Boston. And somehow, after the Knicks stormed all the way back to win 91-90 on Wednesday, the underdog is up 2-0.

The Celtics, who have missed 75 3-pointers through two games, entered as heavy favorites to win the series. But after blowing another big lead at home on Wednesday, sportsbooks are now slightly favoring the Knicks. New York will host Games 3 and 4 at Madison Square Garden.
