Well, there is a certain expectation of success, if you are the laughingstock of the league it's not even worth the effort to show up and boo. Unfortunately, we were just that bad that often.
By the way, I actually have been to Shea so I wasn't knocking it based on what others have said. Admittedly it was a number of years back and I'm sure they've made improvements since my last visit but it is still long in the tooth and the team does deserve that new stadium they're getting.
Booing one's own team in person at a live event is the worst fansmanship possible. Especially targeting the players. Especially students. Terrible. No excuse for such loserdom. I agree with The Jacket. Also, I wish the GBI guy had removed both of those guys in section 222; I heard they were arguing/almost fighting over who is a better quarterback. One of the guys had a voice modulation problem. Jesus X! I'm embarrassed to say that we (the fans) acted like Miami fans or worse at the G-W game...
