This is all very confusing.
You people can't even agree on who your biggest rival is!
No wonder this board is such a shi!tshow.
It's really complex, as dumb as that sounds. I'm actually going to give you the best answer I can:
1- Iowa St. is our natural rival. We are obviously a small state (31st in pop) and we fight over recruits. Iowa has frankly dominated recruting in the state for kids that don't go to Alabamas, Ohio States or if in the western part of Iowa- Nebraska. It was shocking to see a 5* kid grow up a Hawk fan pick Iowa St. in Xavier Foster for basketball last year... especially because he is a big! Iowa usually gets all the better recruits in the state but both football and basketball are getting much better for hs prospects so ISU is picking up better recruits out of the state.
It's also finally to the point where Iowa St. doesn't suck at football. For years that was a lose-lose game for us. Basketball hasn't really felt that way. Their fans are insufferable, albeit extremely loyal, when they win. When Iowa wins, Iowa fans usually don't say much (or at least I don't). When Iowa loses, we hear about it all year.
2A- Minnesota. Border rival and we poach a few recruits out of the Twin Cities. As already noted, their fans have this weird obsession with Iowa as if they are trying to manufacture more of a rivalry. They chant "who hates Iowa... we hate Iowa." At games where we aren't even playing them. That stuff doesn't happen at all in reverse. I really don't care about wrestling too much but both programs are always top 5ish in the nation.
2B- Wisconsin. Another border rival but this one is more of a true rivalry. Both programs are usually pretty good (ranked in basketball and football) but admittedly, they have had way more success in both sports the last 10 years. I don't think their fan base is as annoying as many others will say but they are ridiculously obnoxious drunks (which they probably say about us). Both programs compete to take kids out of Minnesota and the Chicagoland area. Wisconsin has made it a priority to keep their top talent at home with only one major univetsity for football and have done so for the most part. We have been doing a better job of getting in there for some guys like our last QB Nate Stanley (Vikings practice squad) and former starting RB Toren Young. It's the rivalry game that I, as a fan, want to win the most because they are the best.
3- The dorks to the West: Nebraska. Many fans are so delusional and every year they are going to be right back in the mix. They want to downplay all of Iowa's accomplishments while failing to recognize that they have done nothing for years. They can't even make a bowl game without a special invite for being 5-7! The automatic rebuttal is their former coach sucked..., once this coach gets his recruits..., we won a National Title 20 years ago and you have won nothing... Iowa fans in the West have to deal with that all the time. The majority of our states population is in central and eastern Iowa so the rural areas may identify more with Nebraska. They are, by far, the most annoying fan base. That's something all three of the rivals listed above would probably agree on.
Which begs the question: Are Iowans their own biggest rival? I say yes.
