I see so many things wrong with thinking the revenue stream will remain high for the top conferences, and be so little for lesser ones. I just wouldn't know where to start addressing it.
If hard pressed, I'd have to say that the people who follow the WAC, as an example, don't give a rip about what's happening in the SEC if they aren't part of the same program, and will no longer watch their games. They'll choose WAC games, and conferences that are equal to theirs, to watch. Since they will probably even be in different paid TV packages, they wouldn't bother with the big guys.
Just saying, I know I would do that. I already do in baseball. I don't give a rip about other teams, so just have the MLB package for the White Sox. I can read about the rest, don't give a damn about the rest.
I would also do the same thing with a Sunday Ticket offering that allowed me to pick the Packers. I also do this with the Bucks for my NBA package.
