A battle between two of the most obsessively covered NBA teams in recent memory resulted in strong numbers on TNT. Thursday’s Knicks/Heat NBA regular season game earned a 4.0 overnight rating on TNT. Overnights for last year’s comparable Celtics/Bulls game were not immediately available. Despite the strong numbers, the game did not earn the highest NBA overnight of the season on TNT — that distinction belongs to Celtics/Knicks on Christmas Day (4.1). The game also did not earn the top overnight of the week, trailing Sunday’s Mavericks/Knicks (4.8) and Magic/Heat (4.3) games on broadcast network ABC. Locally, the game earned a 9.4 rating in the New York City market — topping than the record-high numbers earned by MSG Network over the past week (7.32 for Hornets/Knicks last Friday, and a 7.34 preliminary rating for Knicks/Nets on Monday), but trailing Mavericks/Knicks on ABC (10.3), reported Sports Media Watch.
