I used to really believe I wanted to see ISU fail at everything. In particular, I wanted to see their football program (figuratively) burned to the ground. I thought I wanted to see the Big XII implode and ISU have to join the MWC where they would go 0-12 for 5 straight seasons before having to downgrade to FCS status.
For me, two things have happened since those days:
One, I got a bit older. Some would say I've gotten "softer", but I'd like to think maybe it's a bit more like "wiser".
Second, I moved out of state, which I think gave me the luxury of observing the rivalry from afar (I live in Colorado - I see quite a bit of both Iowa and ISU gear here but, as you would expect, the rivalry really isn't a "thing" here like it is back home. About the only Iowa-related interaction I get is on FB game days where you'll definitely get some "go Hawks!" and even some brief prediction/reaction chit chat with strangers around town.)
Long story longer, I've come to understand a big part of the fun of being an Iowa fan is wanting to beat ISU every year. If ISU was a non-scholarship FCS program, I promise that rivalry would lose its appeal quickly.
I grew up watching the Hayden 63-0 style beat downs and the game was just a yearly footnote. Once McCarney came along, then it became The Big Game. I thought I hated it, but I think I loved it.
Maybe there are people out there who genuinely need Iowa to never, ever lose to ISU to be happy. That sounds exhausting, but I'm sure they are out there. But, in terms of pure entertainment value, the best thing that could happen to most Iowa fans I think would be a healthy and competitive ISU.
It's hard to find a "healthier" conference than the Big Ten and I think ISU joining would ratchet up the fun factor on the rivalry to a whole new level.
