In an interview on ESPN about conference rivalries Delany put Nebraska and Penn State together, along with rivalries like Purdue and Indiana, Illinois and Northwestern, and Michigan and Ohio State, it may be innocent, but this would be awesome if not!

But the most important thing is that they're played. If you have them in the same division, one of those teams is going to the playoff and one of them is not. If you split teams, whether it’s Purdue and Indiana, or Illinois and Northwestern, or Michigan-Ohio State, or Nebraska and Penn State, if you split them, they can both go. If you don’t split them, only one can go.
