Standing on a big play is different than standing during the whole game. The conversation started with people standing the whole game. Don't turn it into a 'we just stand sometimes' sort of thing because thats not in any way the same thing. I stand on big plays too, and have never said I have a problem with that.
I'm not holier than thou about it, I'm calling it what it is; selfish, dumb behavior by people in our fanbase who have proven they don't know how to behave at football games on many different levels. It's part of a problem. And people act like jackasses if you even suggest they don't stand the entire game. I'm not sure how many games you've been to over the last couple of years, but I've been to them all. It's common at EVERY single game. And it's never the season ticket holders who do it, at least not in the 3 sections I've sat in over the last 3 years. It's always some drunk ass hole who doesn't normally sit in the seats who thinks he's special and that the rest of us had never thought about standing before.
