The traffic that you have to deal with to go to a Saints game is everyday traffic here in LA, so it's understandable that people would be inclined to skip dealing with that same traffic on their day off.
By your standard, the Saints only have around 73,000 fans, because it's only the fans that go to games that are true fans. By that standard, you think I'm a fairweather/bandwagon fan because I'd rather watch the game on TV.
