No. 6 Oregon beat Penn State in Week 5 when the Nittany Lions were still considered as the future 2025 national champions. Since the Ducks' double overtime win, Penn State was never the same. Due to that, beating the blue and white is no longer a bargaining chip into the College Football Playoff.
While Oregon gets the credit for derailing the Nittany Lions' entire season and being the catalyst for their embarrassing elimination from playoff contention, the Ducks have yet to play (and beat) what's considered an impressive team in 2025. If anyone can defeat Penn State, that win isn't all that special to Oregon's resume anymore.
