First of all, I'm not so sure it is "Bama Fatigue" as much as it is the "Same old, same old" fatigue.
Not sure what can be done about it but if ratings fall (or flat), it is logical to assume the networks will offer less in the next round of negotiations. Attendance was falling prior to COVID so that is another issue. Decreasing revenue will get their attention fo sho. There are only a handful of schools that don't really have to worry about money.
I do think we will continue to see the "same old, same old" until more schools compete better in the recruiting arena. More widely dispersed talent instead of having most of it concentrated in a few schools could help competitive balance. Not sure if that would translate to more viewer interest or not. People seem to like dynasties.
