P5 conference teams in 2021. It’s interesting that we played some of the same teams in those two years: we beat Arizona and utah, plus we played Baylor and ASU both years (splitting against them both times).
Other than these two seasons, I don’t think BYU has ever beaten more than 3 power conference teams (or their equivalent) in any one season, including bowl games. And even that has only happened a handful of times , including last year and 1984 (we beat Pittsburgh, Baylor, and Michigan that year).
