Who?
I'll admit that my circle of people aren't so much into Ohio State as they are the Browns, but I don't know of anyone saying that they want to go back to any "old days" when Bama and "the SEC" won the NC. We're all laughing at 3 years of the SEC not even being in the championship.
Also, point of order: The SEC never won a national championship. Individual teams in the SEC won a bunch, including all from 2006 to 2012, and then more from 2015 to 2022. (I know they didn't win all those in that time, but I forget which ones were Clemson.)
