"Garbage time does not score" should be counted as one. This kind of behavior will be regarded as disrespect for the opponent. There have been many conflicts in the NBA for this reason. For example, last season, Warriors center javale mcgee was severely pushed to the ground by Wizards defender brandon jennings after hitting a three-pointer, and Warriors center Jordan Bell staged a violent dunk without any suspense. In fact, there is still a long time before the end of the game, but the opponent is still very angry, and Warriors coach Steve Cole is mad.
There are also some "hidden rules", such as the star whistle, which has now developed into the MVP whistle. For example, during the 20 16 playoffs, American journalists often criticized Stephen Curry for not winning the MVP whistle on Twitter. In fact, most referees can't be fair and just when blowing the whistle because of the players' commercial value, influence and qualifications.
