Getty ImagesThe Key FactsAfter the 2025 expiration of the Big 12 media contracts, Oklahoma and Texas will be competing in the SEC. With 16 teams, the SEC will be the largest conference in NCAA Division I.

According to Forbes' latest list of College Footballs Most Valuable Teams released in 2019, Texas was ranked second with $147 million per year in average revenue. Oklahoma came in sixth place with $129 million. This means that the SEC will now have nine of the 12 most valued college football programs. They generate more than any other college sport.
