Whether BYU can turn this season around is almost an academic question. Efficiency data currently projects them as one of the worst teams in the country, and if they manage to back themselves into a lower-level bowl game by beating a slew of teams ranked even worse, it probably wouldn’t change anything particularly substantial, other than giving them extra bowl practices.
For me personally, the more interesting questions are “why are they so bad right now” and “can they get better?”
I think the answers to those questions are related. They come down to recruiting
Recruiting isn’t the only reason why BYU is bad this year.
