Different fan bases at different stadiums ha e completely different expectations.
The PSL in Carolina’s stadium has ruined any chance of a home field advantage. They are referred to by Carolinians as a “ Wine and Cheese” crowd. Houston is a rich city and I’m guessing it might be the same.
I’ve been to numerous Panther’s games, both against the Bills dressed in Bills garb and as a Panthers fan. It doesn’t matter.
At the Carolina/Patriots preseason game, I was behind a Panther guy with his 7-8 year old boy. I was cheering the Panthers and using zero vulgarity. The guy was giving me dirty looks and the kid was looking terrified. By the end of the game the kid was raising Cane and fist bumping me but the Dad was still being a little pissy about it.
A Pats fan at the end of my row started shooting his mouth off about “ Towmy” while the Pats were getting killed. I got up and booed him and he shut up. Again, my Carolina friends were giving me grief about not starting a fight which I wasn’t close to doing nor do I think the Pats fan was afraid of.
Rust belt fans are a different breed and ticket prices around d the country dissuade the average guy from going to games.
