BYU has gone undefeated one time in the last 100 years. Once. Lavell. Bronco. Kalani. One time. 40 years ago.
BYU is an independent school that regularly recruits in the 80s. A season where they get ranked in the top 25 is special. They win a ton of games vs teams with way more talent than them. If this season with the wins we have makes you unhappy then I'm not sure what you should do except maybe pick a different team.
