They waited so long because these are supposed to be home/home schedules, which means you will just flip the locations the next year.
I've not seen that. Originally it was 5 protected teams, 4 of the other 8 in 2023, and then the other 4 in 2024. That gave everyone one last shot at OUT and protected the most important games.
Games like Tech/OSU I can't imagine not playing for 2 years.
