Apparently during the banner raising of the Boston Celtics' 18th NBA title TNT cut to a commercial break and Celtic fans are mad over it. At first, since I saw that it was Athlon Sports I thought they were just making a narrative to appeal to a certain audience but they had legitimate sources backing up this claim. One of those legitimate sources is Sports Illustrated which they posted on their social media accounts. And even some posts from Celtic fans. Well at the end of the day every network cuts to commercial break at a bad time.
