If the past five editions of the College Football Playoff had included 24 teams, as they will starting in 2027, the Southeastern Conference would have made up a quarter of the field, five schools would have been in every bracket and no fewer than five of the 16 campus-site games would have been played in cold-weather locations.

College Football Playoff administrators and ESPN announced the expansion from 12 to 24 teams on Monday.

The Power Four conference champions and highest-ranked team from the Group of Six will receive automatic bids and the other 19 spots will be decided by the selection committee. About 30% of college football’s 68 power-conference schools will have a chance to play for the title under the format.

Had the 24-team format been in place from 2021-25, 60 different schools would have appeared in at least one playoff. Under the four-team format from 2021-23 and 12-team format from 2024-25, 28 different schools made the playoff at least once.

Alabama, Georgia, Notre Dame, Ohio State and Oregon would have made the field each year.

Under the conference alignments that applied each of the past five years, the SEC would have had 14 different schools combine for 31 appearances, accounting for 25.8% of the 120 slots.

The Big Ten would have had nine schools total 22 appearances (18.3%), the Big 12 would have had 14 schools and 18 appearances (15%), the Atlantic Coast Conference 11 teams and 18 appearances (15%). The Group of Six would have had 12 schools make 13 appearances (10.8%), with Tulane getting in twice. The old Pac-12 would have accounted for the rest of the spots.

The SEC would have led all conferences with seven teams making the playoff in 2024 and '25. Last year the Big Ten would have had six teams in the field and the Big 12 would have had five. The ACC would have maxed out at four teams. The Group of Six would have had four entries in 2021 with Cincinnati, Houston, Louisiana-Lafayette and San Diego State.

There will be a total of 16 campus-site games in the first and second rounds starting next year. Had the format been in place the last five years, cold-weather teams would have hosted seven games in 2021 and five each from 2022-25, and that doesn't include hosts in places such as Kentucky, Oklahoma and Tennessee that can get chilly and snowy in December. Ohio State would have hosted games each of the five years.
