It seems obvious that the only power that regular fans hold is donations, ticket purchase and attendance. I'm not attracted to the idea of just having nobody show up to support the team for home games. It sends a mixed message of protest and/or apathy, depending on how media want to spin it. It almost certainly also has the effect of being demoralizing to the players.
I think it would be far more effective to wage one's protest in the first few minutes of the game. Stand outside silently, stand in the concourse silently, then just start filing in together as one once the game clock hits a certain number. When everyone gets to their seats, bring it... cheer for the team, against Currie and Haslam, off the hook.
It's unsettling to see that many people do something together in silence. It's a tacit threat of what can come in the future if change does not occur. It's also a demonstration of the power of numbers that the fans have. The silent aspect is also pretty key, as it defuses the crazy redneck media narrative and lends impact to the protest.
Basketball season is the perfect venue for this, as numbers are smaller, concourses and ramps are able to carry a larger percentage of the total attendees, and the visual impact of thousands of people filling the bowl together after a few minutes absence will not be lost on the cameras or commentators.
Do it again and again, and it will also change the media narrative from a crazy fanbase that rejected Schiano to "wait a minute, there's something else going on here". Then they can dig deeper into the muck, figure it out for themselves, and shine more light on the problem.
