Only problem with this is that there would be too few similar opponents between teams in each division. Nebraska and Minnesota could end up only having 3 similar opponents on both their schedule (including the game between each other) and having the 6 other games between teams neither team has both played. I would go with a divisional matchup setup like in the NFL. I would do it like this; You play your divisional opponents every year plus one other division for 2 year for a home and home series (you could do just one year with another division and then flip the home sites next time that division is rotated back on the schedule) plus 2 teams from the other 2 divsions. So for Nebraska lets say we get the East division to start with. We play our West opponents and then the East division as does everybody else in our division. Then you do a home and home with one team from the North and South. After two years we rotate the North division on our schedule and play a team from the East and South for a home and home, etc
