For 16 teams you would have to go back to a 6 game regular season and then start the playoffs. College football is not baseball. The more games you play the more injuries and soon you are watching teams play with fewer of the players they started the season with. It wouldn’t solve anything. 4 teams is plenty. Very few years will there be any question about it if you matched the most worthy final four teams.
4 teams is fine and that is why they decided on it.
For an authority on seemingly everything, your basic math skills are lacking. A 16 team playoff means 4 games max for the two finalists. There’s 12 reg season games, a conf. champ game and a bowl game now (14 games). That means a 9-10 game reg season, not 6, if the goal is that no team play over 14 games. Based on all the talk about the ‘plus one’ model, my guess is that 15 games played by the top 2 teams is acceptable If they do an 8-team playoff, then an 11 game reg season is fine and still allows for the champ. games. and a potential 3-game playoff run.
4 teams is the first step and that is why they decided on it. Playoffs mean more money and that is why they will decide to add rounds later.
