The best rivalry was destroyed with the creation of the Big 12 conference,OU-NU.
Just to throw some gas on the fire...
If OU-NU was such a big rivalry, they could've put it in the rules that they HAD to play each other every year.
They did it for Miami/FSU.....you can't tell me that the Big XII wouldn't have done it for NU/OU
:)
The Big 12 should have followed what the SEC eventually did: have two rotating, and one permanent inter-divisional opponent. There was no way the SEC was going to ruin Tennessee-Alabama, Auburn-Georgia, or LSU-Florida because those are always guaranteed to get TV ratings.
