First of all, don't accuse me of ignorance and unwilling to do research when 1) You did not even put a link for the article you quoted. I was the one who found it and 2) I asked you to provide a link for your statement that "The Big 12 contract specifically states P5 will get the same additional money per team." and you have not done so. What does the contract say about G5 schools?
As to your first paragraph, I explained what the article said. I am not making any assumptions beyond that. The article states that when the Big 12 added the four schools, "The legacy Big 12 programs shared money from their current distributions knowing Fox and ESPN likely wouldn't pay equal value for the four new members. Those schools didn't bring pro rata (equal) value to the existing deal. League sources said the conference did not ask its partners for increased rights fees". There is no explanation in the article for why the conference didn't ask for money, and I have no explanation for it either.
In your second paragraph, you stated "On the second contract, there has not been a single source or even a single random tweeter to claim that anyone aside from the P5 teams don't dilute the pool." However, several posters on this board provided tweets; just scroll above.
Also, as I posted separately, I happened to come across this on the Memphis board:
"Bob Thompson, former Fox Sports CEO, said the Big 12 language is very normal. P5 automatic, G5 negotiated." So that would mean that G5 don't necessarily "dilute the pool". The tweets posted above say that UConn would add the same money as a P5 school. The only way we will know for sure if this is true, is if UConn is added and reporters explain the deal.
