Wednesday’s Thunder-Celtics NBA regular season game averaged a 1.0 rating and 1.7 million viewers on ESPN, up 58% in ratings and 57% in viewership from a Nuggets-Heat NBA Finals rematch last year (0.6, 1.09M). Oklahoma City’s win, which peaked with 2.23 million viewers, ranks fifth among Thunder games this season — behind the NBA Cup Final on ABC (Bucks-Thunder: 2.99M), NBA Cup semifinal on ABC (Thunder-Rockets: 1.89M), January matchup against Cleveland on ESPN (1.87M) and Sunday’s game against Denver on ABC (1.87M).
