This is my view: (sorry, I am repeating myself)
1. The new stadium is HUGE. While the top is closed most of the time, noise gets lost in there quickly.
2. Seats too expensive for the average Cowboy Fan. All the "club seats" (15,000) are REDICULOUSLY expensive. Therefore, they get filled up with rich people who are there because they're rich, or people who get the tickets for free from there work or something. They aren't going to get loud and rowdy, and def. don't know WHEN to get loud. At the Commanders game, for example, there were like 4 businessmen behind me NOT EVEN PAYING ATTENTION TO THE GAME. They were just talking. What kind of crap is that? At other games, I had to yell at people in my section to stand up and get loud on 3rd down. That should be automatic!
3. There is TOO MUCH going on during a game. They are constantly playing stuff on the big screen, so fans are paying more attention to that than being loud and actively participating. ...and stupid stuff too, like Olshansky speaking russian. Who cares? They also have drummers, dancers, pole-dancers, etc. There is TOO MUCH focus being taken AWAY from the game with all the extra stimuli.
