The video in the OP was from BEFORE the game, so the outcome had little to do with those fans' attitudes. It was also taken from the endzone, which I am assuming are your "cheap seats" just like at Kinnick. Because from the sound of it, there weren't many problems with season ticket-holders.
Now if I had been there, I would still consider this way over the line, win or lose. As people have stated, this kind of behavior really takes the fun out of the trip. And considering how the game went down, it was even less fun. So I'd be p***ed regardless of the outcome, even though if we'd been up 3 TD's in the 4th quarter, it would have been sweet to watch those idiots leave. I wouldn't say anything to them, just watch. But that's not how things went.
