I originally wanted the team to issue cowbells to the fans but that is prohibited by the NFL and falls into the artificial noise category so until the NFL adjusts the rules, fans are going to have to use other means to distract the opponent.
The intent of fans cheering is not only used to support your team but it is also used to try and make it difficult for the visiting team to communicate. It is also used to try and take opponents out of the game if even for a moment.
In most basketball competitions, fans use chants and sometimes offensive phrases to try and distract a free throw shooter. The Minnesota Vikings are a great example of a team getting their fans into the game.
Their Viking horn call and fan-led SKOL chant are great examples of fans coming together to get into their opponent’s head. If an NFL player gets distracted, even for a few seconds, I believe that is reason enough for fans to come up with a unified chant. That is a few seconds that the player isn’t 100 percent into the game.
Original Cowboys worked extremely hard to try and get their herd across long distances. One of their main concerns moving cattle was the risk of a stampede. The Dallas Cowboys could start the game or even during critical moments, play a video segment of an out-of-control herd signaling to the fans that a collective stomp or “stampede” is needed.
A unified stampede by the fans is a great way to get everyone involved even for those who don’t usually outright cheer. Speaking of superheroes, like Batman, this grade school tactic is so simple yet ties the story of an original Cowboys’ fear into a strength. I can only imagine the sound AT&T Stadium would generate if all the fans generated this low rumble stampede to announce to the visiting team that the Dallas Cowboys fans are here and ready.
