In the NFL, each and every team has a legit and equal path to the Super Bowl. That's just not so with college football.
This. And they even force parity as a business model. Not only through draft order, but by scheduling top teams vs top teams and lower teams vs lower teams each season. Sure, you still have to play all your divisional opponents 2x/year, but if you finished 3rd or 4th in your division you'll play a significant number of games against other 3rd/4th place teams. The format forces an increase in the number of competitive records, meaning a greater variety of teams have a shot at making the playoffs, which drives overall tv ratings through the roof. And pretty much every year there is a Cinderella team (or 2) that go from mediocrity to "playoff contender." That's bound to happen against a weaker schedule. It's
brilliant, and pays accordingly.
Similarly, college basketball, probably the 2nd most successful format in American sports, stresses what I'll call "parity of opportunity." They make no pretense at getting the "best" 66 teams in the tournament, they take the "most deserving" teams, those that win their conference, even at the expense of leaving some better teams out. But doing so creates tremendous, country-wide interest. Every year there are Cinderella stories, often with at least one into the Elite 8. Sure, give any of us 10 guesses January 1 and we could guess half of the Elite 8, but there are always surprises.
Now contrast that with the CFP. A self-serving committee chooses 2 (then 4, now 12) teams they consider the "best," not the most deserving. And it's based on whatever criteria serves its purpose in any given year. Conference champs? Sometimes. Strength schedule? Sometimes, but guess who gets to determine SOS. Best loss? Absolutely (if your name is Bama and you didn't even win your division, much less your conference).
That's why I've never watched an entire CFB playoff game. I just have no interest in a system rigged from the start against my team. Maybe this is the year I finally watch 1. Or 2. Or 3.
