The assumption that underlies most of these complaints about college football not having a good system for determining a hierarchy of team superiority at the end of the season is that someone, somewhere has this responsibility, and that the fans deserve such a thing.
There is no institution that has it as their mission to provide a process through which a definitive college football ranking will be determined. This has never existed, in reality or intent. There has always been fragmentation and confusion at the end of the college football season.
We may as well complain that all chicken eggs that you find in the grocery store are not exactly the same color. There's nobody who is responsible for this, and no one has taken it on as their mission. The issue isn't with the chickens, or with the eggs, or with the egg farms, or with the grocery stores. We have the right to complain that the eggs aren't the way we'd like them to be, with an insinuation that somebody, somewhere should be responsible for fixing this. But that's entirely a statement about our sense of entitlement, and nothing about eggs.
