When bama steam rolls to a championship again this year this will start the conversation
The conversation has already started. It's just a matter of people in power bringing it to the forefront.
The current system was fine when college football was a regional sport, there were only a few channels, & very little TV competition for viewers. But in today's world, with more options, rising costs, etc you better put a good, competitive product on the TV if you want to thrive.
Whether it happens in 2 years, 3 year, or 10 years, college football will be significantly better the day scholarships are reduced. What we're currently seeing just isn't a sustainable product for next 50 years.
