The beginning of the end was Oklahoma suing the NCAA in the 80s to gain access to their own TV rights.
From that time on it slowly became all about the money.
Traditional rivalries have already gone away. Oklahoma/Nebraska, Pitt/Penn State etc. That ship sailed long ago.
Now ESPN, who own the rights to the SEC do 100% hype and happily celebrate and downgrade any successes outside of the Big 10 and SEC.
Today could likely be the end of the PAC
It’s network greed and the Haves putting it to the have-nots
I think just about everything is.
