Im not saying they are a true rival yet. But two years in and weve both beaten eachother in dramatic fashion o eachothers home fields. This is a good start to a series that has some real potential.
I don't think you understand how Northwestern works. Husker fans may come to view Northwestern as a rival but they will never return that sentiment.
B1G schools have been playing each other for more than a century. It would take decades of close games between relevant teams to make this a rivalry. That and or geographic proximity are what combine to make rivals in the Big Ten and I can't picture Nebraska annexing Iowa anytime soon. Don't be like ND where they play a team twice and "OMG we're rivals now!"
