Honestly, I'd rather restore our rivalry with Missouri or the Nebraska series throwing those in place of the Iowa game every now and then. Then you're essentially not losing your non-con rivalry. Plus we still play Kansas State every year for an in conference rival.
Respect that opinion but couldn't disagree more with it. Would rather play Iowa over Mizzou or Nebby 10 times out of 10. Biggest sporting event in the state every year.
