Like Bucky pointed out, Wisconsin has quite a few "rivalries" in basketball. Minnesota, Marquette (that one is like Nebraska's rivalry with Creighton, I think). We also have interesting rivalries with Michigan State and Ohio State. I will say that right now there's not a B1G team I hate more than Iowa. I can't stand Fran and his roster of punks.
I like your coach a lot and I've actually been cheering for Nebraska to get a tournament bid. But I hope you do it without a win over us, because I badly want a one seed for UW.
I understand you not liking Iowa and some of the things that have happened lately, however, don't let the actions of a couple people (Fran going crazy all the time, and McCabe last night) shape your opinion of the whole team. One of my best friends, Mike Gesell, is the point guard on that team and the kid has more character and class then anyone I have ever met
