Purdue also has a protected vs Illinois. Some schools have two and I want to say msu has 3 protected rivals. Idk. It’s weird. And it will get more weird with Texas A&M and ND join.We would need to play 17 teams for a full rotation.
We have 8 conference games per year but i think we have a protected rival game still.
So I think we play each other every year and then 7 other teams each year.
So it will take 2 years to get through 14 of 16 non-rivalry teams...meaning a rotation of just longer than every other year (every once a while you would get 2 years off from a team)
