At the end of the day, Oregon is just a damn good football team. They are 33-3 in their last 36 games.
But because the Big Ten now has 48 teams, Oregon and Ohio State don't play (unless/until the B1G title game)
They simply couldn't get off the field on defense for most of the game. Oregon was constantly in 3rd and 2 situations and PSU was always in 3rd and 8. Oregon was 5 of 7 on 4th down. Very frustrating.
