Reality is that BYU could be in the playoffs with 5 losses, as long as they win the conference auto bid by winning the conference championship game.
They don’t have to be perfect. They do have to win the CCG.
Goal posts haven’t moved at all. Some years will require a better record than others to get into the CCG. And, of course, they have to then win it.
But they don’t have to go undefeated.
