I wouldn't mind that. So that means we would play 5 or 6 (9 game conf. sched) out of the other 12 teams. To me a 9 game schedule and you play half of the other teams each year and then switch in 3 and 3 out each year. That allows you (except for the first year) to play a home and home with each team before they are off your schedule for 2 years. Also, by doing 3 at a time instead of 6 for 2 years then switch you don't have the same exact schedule 2 years in a row. To me that would be acceptable.
Example of how the other 6 teams would work for Iowa (assume pitt and kansas for example)
Year1:
OSU
Purdue
Illinois
Marlyand
PSU
kansas
year2:
OSU
Purdue
Illinois
Rutgers
Michigan
Pittsburgh
Year3:
Rutgers
Michigan
Pittsburgh
Northwestern
Indiana
MSU
Year 4:
Northwestern
Indiana
MSU
Marlyand
PSU
kansas
This way you play every team 2x every 4 years, plus your 3 rivals every year.
