Where the B1G failed is that they relied fully on the BTN and did not care about people in the seats. Given that the CCHA went away- just picking up what they had, and adding the same thing to Wisconsin and Minnesota would have been a good way to start- even starting in Minneapolis. But they didn't. And when fans went directly to them telling them what to do, they totally ignored the suggestions. It would be easy for a handful of B1G promoters, who I'm betting they have at EACH school, to go to home games. It would also be easy to get large amounts of promotional stuff FOR FREE (and gladly handed out) from Visit Detroit and Visit Twin Cities to help fans go to each city.
Why they ignored that? No idea. IMHO, even with renting the Joe and the X, they could easily have done better in terms of income than the home site set up. This isn't rocket science, it's marketing 101.
