Let me add one other thought.
A one-and-out tournament is a method for getting a winner and having a party.
A real championship is best exemplified by Major League Baseball and the National Basketball Association. Teams play each other for multiple games, and a good idea of how closely matched they are is really brought out.
The winner of a 5 or 7 game series is probably the better team. Even in a 4-3 split, it is an intangible at which they are better, even though extremely closely matched.
My point is that Ohio State could play Alabama next week and lose. Play them 7 games, and you’ll probably be able to pick the actually better team. Our former coach in Cincinnati, Brian Kelly, now with Notre Dame, used to quote someone who said that any FBS team can plan for, get lucky, and beat any other FBS team. Maybe just one in a hundred chance, but one game isn’t necessarily the best indicator.
Football has never had a series to decide a winner at any level. The abuse to the body really limits playing to once a week.
But you have a great point about it is not always the best team winning, but who has the better game. 1987 Fiesta Bowl is a great example. Who thinks Penn State would have beaten the Miami Hurricanes in a multi-game series that year? But they did in one game.
That’s football. They never play each other 7 times in the same season. Pro, highschool, college, peewee, or at any level.
The problem is that in football, injuries are a much bigger factor than the other sports. So if one or two key players get hurt, it totally changes the complexion.
And there definitely could a lot of trying to intentionally hurt opposing players to try to gain an advantage, if football did series like the other sports.
