"The inadvertent whistle apparently prompted BYU student-athlete Mark Bigelow to enter the playing floor from the bench area and interfere with an opposing playerthus resulting in a technical foul against the Cougars. Had the inadvertent whistle been immediately recognized, play would have been halted and Mr. Bigelow's action would not have prompted a technical foul. "
Am I missing something here? Biglow left the bench area whistle or not and went onto the court and "interfered" with an opposing player. So if there is a timeout or a whistle to stop play it is OK for a player on team A's bench to come onto the court and confront a player on team B in any way?
Where is my rules book?
