I would add that the dual meet series between ISU and UI is hugely lopsided in favor of UI - but there is a reason for that.
Similar to the football programs, the two schools hardly wrestled each other for many many years. When the series did pick up again, I think in the 1970s, UI was just starting to turn the corner, and of course Gable had left for UI. Not only that, but when the series started back up, they were wrestling twice a year. So should anyone hear smack about that, look the results up in the archives.
UI probably won a couple of meets many decades ago, but the simple fact is that they weren't wrestling each other when ISU was routinely 2nd or near the top.
I would add that it is not inconceivable that ISU will one day be historically the very best program. OSU is number 1, and UI 2. ISU would need quite a few team titles to stake a claim, but neither was UI wasn't anywhere close 30 years ago.
