Context: In July 2021, after 25 seasons as members of the Big 12, Texas and rival Oklahoma accepted invitations to join the Southeastern Conference (SEC) no later than the 2025 season. In February 2023, the Big 12 announced that the two schools had negotiated a combined $100 million early termination fee in order to leave for the SEC a year before the schools' media rights deal with the Big 12 was set to expire. The Longhorns football team will continue competing in the Big 12 through the 2023 season before moving to the SEC in 2024. Question: What team other then Texan Longhorn accept an invitation to the SEC in July 2021? OriginalAnswer: Oklahoma ModelAnswer: The Big 12 Conference, a long-standing collegiate athletic conference in the United States, announced on July 1, 2021, that it would be dissolving. This decision came after years of speculation about the conference's future and the desire of some of its members to join other powerful conferences. As a result of the Big 12's dissolution, several teams were left without a conference home. Among these were the Texas Longhorns, who were an original member of the Big 12. The University of Oklahoma, another Big 12 member, was also considering joining the SEC. The SEC, with its strong reputation and competitive football program, decided to extend an invitation to the Longhorns and Sooners to join the conference. Both universities accepted the invitation, and as a result, the Big 12 became the first major college athletic conference to be dissolved. The addition of the Longhorns and Sooners to the SEC was a significant milestone in the history of college sports, as it expanded the SEC's membership to 16 teams and further solidified the conference's position as one of the most powerful and successful in the country. In summary, the only team other than the Texas Longhorns that accepted an invitation to join the SEC in July 2021 was the University of Oklahoma. This move allowed both schools to be part of a prestigious and competitive athletic conference, with the SEC gaining two prominent members.
