We already play Wisconsin, Iowa, and Nebraska every year.The 3 protected rivalry, no divisions idea would be awful for Minnesota. While we would get to play our rivals it would hand one of the toughest schedules to Minnesota year in and year out. Wisconsin and Iowa are usually upper tier teams and both Nebraska (most likely) or Michigan (Jug) also have an awful lot of resources. Wisconsin and Iowa are typically our hardest games, now sprinkle in even more games with Ohio State, Penn State, Michigan than we already have.
I'd prefer Michigan over Nebraska, due to them actually being a good school that is a peer to us academically, and having a historic rivalry trophy game.
So yes, that game every year on paper is an increase in SOS for us. And any scheduling method that has us playing Ohio St more often is also an increase in SOS for us .... as it would be for any other Big Ten team.
Penn St, Michigan St ... meh. No more difficult than playing Iowa and Wisconsin.
Purdue is arguably Illinois' biggest rivalry game, and a trophy game. They take it every bit as seriously as the game with NW. Similarly for Purdue and its game with IU.Also, most B1G teams have anywhere from 0-1 historical rivals. There would be a lot of forced ones like Illinois drawing Northwestern, Purdue, and Indiana every year based on proximity. This season excluded, that would be a cake draw.
Your 0-1 is not accurate ether, except maybe for Maryland and Rutgers. https://en.wikipedia.org/wiki/List_of_Big_Ten_Conference_football_rivalry_games
