KU will not be in the Big 12 in 2025, and neither will multiple other teams. Any report/article that tells you different is nothing but click bate. For the past 3 years, the SEC and Texas/OU were able to keep it completely silent and you will see the same from other conferences until all hell breaks loose. Instead of reading articles written by so called experts ask yourself these questions:
1) Why did the Big 10, PAC-12 and ACC form an alliance? Before reading the next question, be sure to think out your answer.
2) Why didn't they invite the Big 12 into the alliance?
3) What is the best path forward for Big 10, Pac-12 and ACC, as well as all of college football?
My answers:
1) It was reported they formed an alliance to stop the playoff expansion so the SEC wouldn't end up with 2 or 3 or 4 teams in the playoffs. They also formed this alliance so they wouldn't pick off each others teams (rumors were the USC, UCLA, or Oregon to the Big 10). If this is true, adding the Big 12 to the alliance would have added strength and made sense.
2) Big 12 wasn't invited because those conferences are unbalanced and need to get to 16 (or possibly 18) teams to allow two divisions and a true conference champion. They need more teams. The Big 10's scheduling is a nightmare that doesn't allow many annual rivalries and depending on a teams yearly schedule, can cause a team with a weak schedule to win out over a more worthy team (East Division has won the last 8 Championship games) . If they included the Big 12 in the alliance, that would leave tier 2 teams as the only teams to add.
3) Since the start of the College Football Playoffs, two years the Big 10 didn't have a single team in the playoff (2018 and 2019), and only 2 years has the Pac 12 had a team in the playoff (Wash 2017 and Oregon 2015). SEC has had a team every year (and 2 one year). By eating up the Big 12, these 3 conferences can get to a true champion, and with voting power create a national championship playoff that would consist of 8 teams (2 from each conference playing in conference championship, and 4 conference champions advance to play for the national title). This is also creates more TV money (only paying 4 major conferences big money vs 5 right now), makes it so the SEC cannot have multiple teams playing for the title, and it allows for a true national champion.
All these conferences know that college football needs good matchups to keep interest in the game. With attendance and viewership going down due to unbalanced teams, something has to change for college football to continue to be relevant. All the good teams being in one conference doesn't help. The NIL is just going to keep the elite more elite. For the past 5 years, you could write in 3 of the 4 the playoff teams before the season started. Alabama will be champ again, with Ohio St, Clemson and one of Notre Dame/Georgia/OU probably filling out the last spot. And most of those have been in the last 5 playoffs. Not good for college football and the other conference AD's know it.
