So your genius plan is that we give up our season tickets which would quickly be scooped up by other fans or a ticket broker and make no noticeable difference to the Cardinals. Boy that would really show them. That makes about as much sense as someone who never eats at Chick-fil-A announcing that from now on they are boycotting Chick-fil-A. Any more bold moves dreamed up from your couch?
Tickets are partially pooled income. Merchandise, parking, etc, is 100% team profit.
I'm sure they would notice an even more disproportionate fan base in the stands.
This team does not care about you, only your money. It barely seems like they care about winning, but why change anything when fools and their money are so easily parted?
