every year. This is not a BYU thing. It's an everybody in sports thing.
BYU does beat the bottom half of the P-5 consistently. They just don't do it ALWAYS.
BYU has had ONE undefeated season in its history. They've had just FOUR one-loss seasons.
Even in the three of the one-loss seasons, BYU lost games they should not have.
I think you can find exactly two seasons in all of BYU history they have not lost at least one game to an inferior team.
