ESPN Stats and Info puts Boston's offensive woes into perspective:
The Celtics were held to 11 points in the third quarter, tied for their lowest output in a quarter since the Indiana Pacers held them to 10 points in the fourth quarter in Game 2 of their 2005 Eastern Conference first-round matchup.
In fact, they were held to one point per minute over the second and third quarters while making just 9 of 37 shots from the field. They made 24 of 42 shots -- 57 percent -- over the other two quarters to stay in the game.
If the Celtics had gotten to the free-throw line, they might have been able to win the game despite their poor shooting stretch. Boston attempted only nine free throws in the game. In 1,879 playoff games over the last 25 years, the Celtics are one of only eight home teams to attempt fewer than 10 free throws.
