The map is not what the B1G does. There are no protected rival pods. For example using a B1G style approach, ISU might get KU, K-State, and Colorado as its protected games. But Colorado doesn’t have to have the same group - it could have ISU, Utah, and Arizona State for example.
I agree that we should copy the B1G’s approach and ISU should get KU and KSU as 2 of its 3 protected games. Don’t really care what the 3rd one is, if anything at all. I think 15 schools in the B1G have only 1 or 2 true “protected” rivals and only Iowa has 3. The others are temporarily protected to make the schedule work and then they reset on a 3-year basis.
