 The NFL's rules to "legislate the fans", and help visiting offensive players hear the snap count, have been controversial from the start.In one notorious example, then-Cincinnati Bengals head coach Sam Wyche and then-quarterback Boomer Esiason "protested" the crowd noise rules during a 1989 nationally televised preseason game against the New Orleans Saints by constantly complaining to the referee about the loud crowd noise inside the Superdome.The league will still allow stadiums to post visual noise meters and other scoreboard messages to incite fans to make noise, but they must cease when the play clock is down to 15 seconds.
