I think, and this is obviously just my jack*** opinion, the execs and presidents have cynically concluded that people will still watch CFB despite the massive changes in regional conferences, schedules, player attitudes, player allegiances, roster turnover.. Train wrecks attract eyeballs. Sports media love controversy, chaos, problems. Cynical AF. More broadly things like COVID-19, controversial orange-tinged politicians, catastrophes are great for ratings. And, like the NFL they are now catering to the gambling crowd. The idiotic injury report thing, sports betting legalization, etc.
They could be right. Ratings were purportedly up for the NCAA last season.
