People have been refusing to go see the Bengals for years. Can't even legitimately sell out a playoff game. You know why? Because we knew what we were going to get. Why spend the money to watch that shit?
NFL games are terrible to go to live, anyway. You go to a baseball game, you sit down and relax. Have a beer. Win or lose, fuck it ... you are at a baseball game! In football, everyone is just angry. And when the team is doing good, they stay angry as they yell at opposing fans. You want to sit? They are like "STAND FOR YOUR WARRIORS!"
So, who wants to pay that much to go have a terrible time?
