Why do you consider Oregon and Washington above Auburn? Nike money? Affinity for Puget Sound?
If Auburn came to the Big 10, they would suffer the same fate as well. USC likely will. They are just a touch more "premier" program than the others.
You made a comment before about Ole Miss being a better opponent than WVU, but what if they are 5-7? Are you gonna change your tune? Because you sure have put Auburn down.
At the end of the day, USC, Oregon, and or Washington are not going to be yearly 9-3 type teams playing a Big 10 schedule unless PSU and Michigan and OSU fall off hard. Look at Nebraska. Powerhouse for 25 years. 9 win team in the Big 12. 7 and less in the Big 10. With every coaching hire, it's "he'll bring em back!" And everyone has seemingly gotten worse.
