You just say that because you want your big brother to consider you a rival. Funny how no one else in the conference has ever bought into that narrative.I think you guys will start to develop a natural rivalry with Wisconsin over time, simply due to the sheer number of big games you two will play against each other. Most years, the NU/UW game will likely be the East Division de-facto championship. Nothing breeds a rivalry quite like competition.
Geographically, Iowa makes the most sense but I'm not sure the Hawkeyes can be consistently good enough for that to really take off.
Wiscy already has Minnesota, but I always got the impression that rivalry was way more important to the Gophers than the Badgers.
Also, there can be more than one rival. Several schools have two or three.
Oh Sparty... you can climb Mount Everest, but at the end of the day you'll still be mSu.
