Besides 1 bowl game with both teams unranked, Pac12 was the higher ranked team in each game. They went 3-4 in bowl games and 5-8 against P5 teams in the regular season!
Add on the 2021 season of complete garbage where they ended up 3-16 against P5 teams and 5-6 agains the MWC (Yep, a losing record against the MWC).
Overall the Pac12 is flaming garbage and they fact they had so many teams ranked is mind blowing to me.
