The last two seasons in football have seen the Pac 12 with almost a cloak of invisibility in terms of OOC and bowl season success. While the Oregon win over Ohio State was the best reg season win for any conference. That is sadly the lone pillar of success amongst a thick forest of failure the last 2 seasons.
Quick note, it was 3 seasons ago with the Oregon win over Utah. That and I am pretty sure the Big12 champ winner in the 2019 season would have made the CFP over Utah. But I will admit that was a debateable point that is likely to show bias in terms of whether the Big12 or Pac12 had the stronger SOS in total.
