BYU played 100% G5 opponents in 2020 and have had zero NY6 games.
Cincinnati got a massive bump from playing Georgia this season
UCF got a massive bump from playing LSU in 2018
Memphis got a massive bump from playing Penn State in 2019
Take away those games and BYU is either ahead or right there.
The P5 schools that aren't winning are almost all going to be way behind BYU.
