When I think about option of separation, either voluntary or forced, I think of the FCS playoffs. Good football being played. Entertaining. Some good regional rivalries. But on a national landscape, no one really cares. It's an afterthought. It's football that the casual fan does not know is happening maybe until the championship game in Frisco at 2 pm because it's on a linear network.
Don't separate. Keep fighting. There are other ways to show the fat cats that you have value.
Also, why the hell is Dooley all the sudden so invested in this? What's he got to gain? What do any of these advocates have to gain aside from potential $?
