The Celtics jumped off to a monumental 29-10 advantage after one quarter of play, leading at the half, 57-38. But the Hawks responded in spades in the third quarter, going on a 31-16 run to pull within four points.
It was a back-and-forth battle in the fourth quarter as the Hawks threatened to take the lead inside a minute to play. They got the final shot with the score tied, but Josh Smith was unable to convert.
Both teams wouldn't give way in overtime, either, scoring nine points apiece and sending the game into double overtime.
The Hawks not only shot 36 free throws, they also scored 24 points on 21 Boston turnovers.
