The New York Knicks might have tanked on the court against the Boston Celtics, but they were a slam dunk in the ratings category.

Game 4 between the Celtics-Knicks earned a 5.0 overnight rating, 9 percent higher than last year’s Sunday 3:30 p.m. game between Cleveland and Chicago. It was the highest-rated sports show of the day.

The three playoff games that were carried on MSG Network (Game 4 was an exclusive ABC telecast) averaged a 2.96 household rating, up 96 percent (1.51) from the Knicks last postseason appearance in 2004.
