The best thing to do to people who vastly overpay to enter enemy territory and buy a ticket to see their team in the playoffs is to stomp them into oblivion and force them to contemplate all the things they could of bought with the money they spent to see their team violated in front of their eyes.
This discourages future purchase decisions and preserves more of a home field atmosphere so it's the Cardinals civic duty to show up and teach the cheeseheads no one comes into our house and expects to be entertained, you expect an ass whooping and pray for better.
