Forget about Oregon. They turned out to be not so much. (Besides, they are 1-9 all-time vs. the Buckeyes.) The truth is The Buckeyes OWN the PAC-12. Here's why:
2017 Season: TOSU -24, USC - 7 (Beat the PAC-12 champs in the Cotton Bowl.)
2018 Season: TOSU - 28, Washington - 23 (Beat the PAC-12 champs in the Rose Bowl.)
2021 Season: TOSU - 48, Utah - 45 (Beat the PAC-12 champs in the Rose Bowl.)
In those seasons TOSU doesn't get into the CFP, they get to beat the PAC-12 champion in some major, New Year's Day Bowl game. Not bad.
