You're displaying your ignorance on this topic. ESPN controls 100% of SEC rights through the mid 2030s. Fox controls 100% of B10 rights through an indefinite period. Whatever rights that other networks have for televising SEC or B10 CFB are sublicensed from ESPN and Fox. In addition, ESPN controls CFP rights through 2031-32.
It is a duopoly and they control the sport as they see fit including realignment and relegation.
So, what are they going to do? Again split it up, to networks that dont want the content or are not willing to pay more than ESPN or Fox? They control it because they pay the most, and are sports networks with multiple sports channels to fill content on. Others are either not sports only channels, or have 1 subchannel that is sports, but is a very low value channel, at least at this point that paying huge amounts for content on those channels doesnt make sense.
Are you saying they will break up ABC/ESPN? Fox? How does that equal more money for everyone? They have content in a lot of sports, but because of 1 sport they are going to be broken up? Are they going to force ESPN to give up its rights to another network? That wants to pay less?
Are they going to throw out the Supreme Court decision that took the media negotiations away from the NCAA and now allow them to be a central media negotiator, similar to the NFL?
Seriously, I may be ignorant on the fine details on what qualifies of a duopoly, but you may be on the reality of the situation and what exactly would be the answer, and how that answer would be a benefit for anyone, and really what and how exactly anything is done to change the system.
Unless you believe that Congress or the Supreme Court is going to become the new NCAA and govern the entire system, and revert it back to something from decades ago, I dont see it happening.
You hate the duopoly but want to create a monopoly that controls the entire system. It makes no sense.
