The following downright-startling numbers go a long way toward explaining why they fell short.
25: Points in the second half for the Celtics, on 25 percent shooting. Jeff Green, who had 20 by halftime, only registered six points after that.
8: Boston points in the fourth quarter. The C's only took 11 shots, making three.
4: Bench points for the Celtics. All four came on Courtney Lee free throws. Jason Terry went 0-for-5 in 20 minutes, with no assists. Jordan Crawford did not attempt a shot in the 10:46 he played.
33: Bench points for the Knicks, led by Sixth Man of the Year candidate J.R. Smith's 15.
5: Players on Boston's bench who did not make an appearance. No forward or big man entered the game to relieve the starters—Shavlik Randolph and Chris Wilcox wore t-shirts the whole game.
21: Total turnovers committed by the C's, which led to 20 Knicks points. They lost the ball eight times in the fourth quarter alone, leading to pivotal opportunities for New York. The Knicks only turned the ball over 13 times.
4: Total assists by Boston guards. Avery Bradley accounted for all four. Paul Pierce had seven, KG had four, Jeff Green had two and Brandon Bass had one.
28: Points Carmelo Anthony had after three quarters, making only nine of an unfathomable 24 shots. He went 4-of-5 in the fourth quarter, when New York mounted its comeback. He finished with 36 points.
9-of-25: New York's three-point shooting numbers. They were 22-of-56 in these squads' two previous contests.
15: Steals by the Knicks, compared to Boston's five. New York capitalized on cross-court passes, poor execution off the dribble and failed spacing.
10-of-27: Paul Pierce and Kevin Garnett's combined numbers from the floor. Pierce was 1-of-7 from behind the three-point arc. KG only made one shot out of five attempts in the second half.
4: Offensive rebounds for the Celtics. The Knicks had 10 boards on the offensive end, winning the battle of second-chance points 12-6.
10, 9: Points and rebounds Kenyon Martin registered for the Knicks. The Celtics showed interest in the veteran earlier in the season before New York signed him.
0: Instances during and after the game in which Boston fans truly thought the Celtics are better off without Rajon Rondo.
