Well, it's June 30th. It's the 1 year anniversary of USC and UCLA's announcement they were leaving the PAC to join the Big Ten.
Generally it's accepted that if the Big Ten or Big 12 were adding any more teams in 2024, they would need to announce it by today. Although some think the real deadline is August 1 or even as late as December 1.
But I believe if nothing is announced today, then nothing else is going to happen in realignment regarding the 2024 season. Stay tuned. We shall see.
