Last season, College Football had one of its biggest changes yet as team's left the Pac 12 and Big 12 starting to form two true "Power Conferences" in the SEC and the Big 10. The other massive change that accompanied it was the change of the College Football Playoff format as the Playoff went from 4 teams to 12 teams giving the Conference Champions of the "Power 4" conferences an automatic bid and one automatic bid to the next highest ranked conferences.
The results were an incredibly fun College Football season but, the format clearly had massive flaws. Allowing teams the extra wiggle room with losses took some of the chaos away from the sport as for example, Michigan beating Ohio State would've kept the eventual National Champions out of the College Football Playoff race most years. Despite all the drawbacks, rather than keep the format as is for now the sport will likely change again as conference commissioners look to expand the Playoff to 16 teams.
Under the proposed new model, the SEC and Big 10 would get 4 guaranteed bids each into the College Football Playoff with the ACC and Big 12 each getting 2 bids, the Group of 6 getting a bid, and 3 additional teams getting At-Large bids.
Expanding the College Football Playoff to 16 teams after one season in the 12 team format would be a massive overreaction as there is only a one year sample size under the current model. Giving team's additional extra wiggle room only makes the regular season less important as the stunning losses will become almost meaningless.
The second massive issue with this proposed new format is the issue of potential "Play-In games for the College Football Playoff. Rather than letting the 4 teams that had the best record in the regular season take the Automatic bids, the SEC and Big 10 would allow teams who finished 5th and 6th in the SEC another chance to prove they're playoff worthy when they had 8 conference games to do so.
For reference, last season, 3rd ranked Tennessee would've been forced to face 6th ranked South Carolina while 4th ranked Alabama would've had to face 5th ranked LSU despite crushing the Tigers in Baton Rouge.
The sport is constantly adapting and changing but, throwing the entire format out of the window after one season is a change that doesn't need to happen. Every team has an ample amount of chances to prove their ability on the field and there's no reason to allow a team that is National Championship worthy during the season a chance at winning the National Championship.
