They can call it a champion. They can claim it's a national champion. They can claim authority but I reserve my rights to question their authority and the legitimacy of their champion. Their "champion" didn't prove it on the field to my satisfaction. No, they were voted in while an undefeated team was left out.
It's as if the world governments got together and claimed the earth is flat. They can rewrite all of the textbooks and brainwash people all they want. But it doesn't make the earth flat.
