NFL latest stadium change: More crowd noise | Journal and Courier | jconline.com NFL eases up on restricting crowd noise | ProFootballTalk Before the jokes about how much noise there is at Gillette Stadium commence, I do have an issue with one part of this proposal. The league has also said teams can use audio to encourage crowd noise until 20 seconds remain on the play clock. In the past, any audio used to encourage crowd noise had to stop with 30 seconds left on the play clock. So if a team goes to a hurry up or no huddle offense, and the quarterback is calling the play at the line of scrimmage or calling an audible, and there is more than 20 seconds remaining on the play clock, then it is okay for the stadium operators to artificially creat as much noise as they want? How is that fair? Is the fact that the Patriots often employ this type of an offense strictly a coincidence?
