If this actually happens, I can only hope that the flag goes down as a bench penalty like a bench T in hoops. Especially in HS. Any coach who tolerates this #$#@ from his players in a scholastic athletic contest should be reprimanded. Let's not make the refs the bad guys. In fact, they should be congratulated for insisting on some perspective.
Spent one year as a commissioner of a high school league. One team displayed such behavior, removed the coach, behavior reappeared under new coach, team forfeited last seven games. This is about much more than winning.
