I may end up being wrong about this (and to be clear, I really hope I am) but the few guys pounding their chest over the B1G and Pac-12 cancelling need to explain to me how this isn't going to happen to the ACC or SEC. Looking past the dysfunctional mess that is the Pac-12, everyone appears to agree that the Big-10 is not doing this to be altruistic. That means the math is stacked against having a football season, and the math is going to be the same everywhere.
There is so much money the B1G is leaving on the table by walking away. Thinking that the people in charge of the B1G are doing it for political theater or because they haven't appropriately weighed their options seems like a tall assumption. I don't see a scenario where Michigan/Ohio State/Penn State/Nebraska/Wisconsin/Iowa all willingly walk away from their biggest advertising boon, piss off their big-name midwestern donors, and hurt all other sports that rely on football income without thoroughly exploring all options and coming to the conclusion that they are essentially forced to do it by the reality of the situation.
The Big Ten isn't some powderpuff organization that takes hits of a few hundred million dollars lightly. They speak money, prestige, and national brand recognition as well as any large business in the country. I find it hard to believe they made this decision without it being their only option once they looked at the information. You can argue with what the underlying cause of the math is, but like I said the math is the math.
