Speaking of home stadiums I think the NFL has an issue on their hands and if I were Harbaugh or any coach I would be livid with the league about the unfair advantage the Hawks have. Not that their crowd makes it hard to hear on offense and teams have to take timeouts to avoid penalties. That's all fair imo. The problem is when their crowd makes it sooo loud that the refs are unable to safely officiate a game. Their D players play well beyond the whistle cause nobody can hear the damn whistle, and even when making a big play on offense can be very loud which is what resulted in Cullivers penalty of playing beyond the whistle.
They can't have it both ways. If their crowd is so loud that the whistle can't be heard then the NFL must do something to address the issue. Be it louder whistles, hearing aids of some kind, something. To do nothing is simply unsafe, and completely unfair.
