The Ohio State football program has benefitted each time the format of the College Football Playoff has changed. When the first four-team CFP started, they won the national championship. In 2024, they won the title when the first 12-team Playoff started.
Now, the Big Ten is pushing for more expansion. They recently released a proposal for a 24-team CFP that wouldn't involve any conference championship games. In that proposal, it would be a 23+1 model, meaning that just one G6 team would get a bid. This model would see more on-campus games.
This ridiculous model would pretty much take away any value of the regular season in a sport that had the most important regular season of any sport.
