I am not a Seattle fan or hater so my comment is completely unbiased. Where it is unfair is that Seattle is able to create the noise because of it’s geographic location coupled with low clouds and low pressure system. A stadium like Miami could never make that much no matter how loud they yelled. For you to have the advantage to not allow apposing teams to audible is BS. It is sad for Seahawks cause they are a good team and it takes away from their wins, Unfortunately I have to give the MVP award to the architect of the stadium who managed to maximize the acoustics of the stadium. The reason it is different than a dome or time zone advantage is because those teams have to play games outside at some point or travel westward. Seahawks will never have to play in the same type of noise pollution as their opponents, When you are literally making it impossible for a QB to change the play to react to a defensive lineup you are affecting the game, and taking away from the talent. If all teams had the capability to create the same volume it would be different, I have been to Century Link Field, showed up early and I could hear people talking 100 ft away.
