We know for a fact that Nielsen ratings are not all encompassing. We also know that ratings are driven by more than just matchups. The day of the games, time, and channel are all factors (and all can be controlled by ESPN/FOX/CBS). So ESPN will point to ratings to justify cutting ACC money. And they will be able to present a strong case (because it has been built that way over time). The ACC has no clear cut way to challenge ESPN on the value of FSU/Clemson vs other ACC schools. Even without the ratings, ESPN can cite market value that they determine internally. FSU and Clemson historically have more titles than the rest (national and ACC), more wins, more draft picks, more fans, etc. ESPN holds all the cards in this matchup if the ACC ever challenged them.
