International Man of Mystery
There are certainly degrees of rivalries. You could rank rivalries from the most inconsequential - when teams happen to be in the same division (Nebraska/Purdue) - to the most strident - when teams like Nebraska & Oklahoma competed yearly for conference supremacy. For example, Iowa has several rivalries, some more important than others.In addition to the poll being fairly split, it would seem that if it were not at least somewhat a rivalry - there can be different degrees, can't there? - this thread would not be be on page five.
In general, every team in your division is a rival, every team in the other division is a bit of a rival, every yearly or semi-frequent two opponents are rivals, etc.
It's where people's varying definitions of what is or isn't a rival that makes for conversation. To more than half the respondents on a Husker football message board, Iowa and Nebraska aren't "rivals" yet. That's probably the most damning thing for pro-rivalry folks. If you can't get consensus here, Joe Public isn't buying in.
