How about head to head? Or bowl wins in the last 10 years? Or attendance? Bowl games since 2000 have Minnesota at 10 and ISU at 8. I'd say that is much more comparable than ISU/Indiana.
Head to head? You want to use a single head to head matchup to decide if you are on equal footing?
Why is it now bowl wins in the last 10 years? In your earlier post you were using a 15-20 year time period? It might have something to do with the Gophers winning 3 bowl games in those years you conveniently decided to remove form your criteria.
10>8.
But I guess I did ask you to find anything you were at least comparable to Minny with. You may have had to move the time period 10 years but you found it.
And I didn't bother to look up the attendance stats because Iowa fans sold out the Metrodome every 2 years before TCF was built.
