Dwell on this.
If we all truly care about the team and want to see another SB win, we would need to stop attending games, buying gear, and stop watching the games to really hit Jerry's pocket book.
Nothing will get his attention and cause him to consider letting go of the GM role like declining profits. He doesn't care about fans and our opinions unless we make him care.
Ask yourself, are you willing to do that for a period of time, for the long-term good of the team, until he finally respects our wishes and sells the team.
