I don't follow that logic. Projected viewership directly affects the negotiated conference media contract which then gets shared by the conference teams.
Edit - sorry
Two different conversations going on.
One - Projected viewership is not under the control of the league, which game is selected isn't either, neither are the advertising contracts. How much AT&T pays FOX to run commercials during the games it chooses to air is of no consequence to the league. The network is simply trying to recouping their costs that will be paid to league and it's teams.
Two - my response to you was about Washington and Oregon bringing enough to the table to join the Big Ten.
Without looking at the ratings, which games garnered the highest ratings for Washington or Oregon is in question.
I looked at Clemson at some point when having a similar discussion. If I recall, Clemson had a game against Georgia to start the season and drew like 9 million viewers for that one game. It was on ABC in primetime. During the year they had like 5 additional games that were on the ACC network and only drew like 200,000 viewers. When you looked at the season as a whole, Clemson averaged about 1.7 million viewers for the 12 game season, or a little shy of 21 million people watched all of their games for the season. Basically, 1 game accounted for almost 1/2 of the people who watched their games all season. So I ask, was Clemson the draw or was it Georgia, or was it simply the matchup. Does Clemson really bring that much to the table? They don't have population and only a couple of games drew solid rating mostly because of when they were played and the opponent. Then you look at Ohio St and that year they averaged more than 5 million viewers per game over 12 games.
So I ask, would you pay Clemson $100 mil per year to be a part of your league? Oregon has better viewership than Clemson, they fall somewhere in the 2.5 mil per game category, Washington was less than 1 mil per game.
Using the same data set provided in that tweet from 2016-2021 (excluding 2020) Oregon only had 5 regular season games that drew 4 million viewers, Washington had 3 games. For Oregon, only 3 of those games were league games, the others were games played against Ohio St and Auburn. Washington had only a game against USC and then games against Michigan and Auburn that drew over 4 million.
For Oregon, 3 of the top 7 watched games were all in 2021, where they averaged 2.5 million viewers per game.
I just don't think the numbers say what people think they do with regards to expanding with Oregon and Washington.
