Date: 5/13/1994
Game: New York Knicks @ Chicago Bulls

Commissioner David Stern attends tons of contests during the NBA season, and during the playoffs he's at a game nearly every single night. So when the Bulls and Knicks met in a contentious series in the 1994 Eastern Conference Semifinals, Stern had a front row seat for all the biggest moments. One thing he surely did not like seeing was the rumble between Jo Jo English and Derek Harper, which spilled a little bit into the first row and involved a pileup of pretty much every player on the court. It was seen as enough of a problem that in the offseason it spurred the rule that results in an automatic suspension for any player leaving the bench area during a confrontation.
