I mean 40 times since 1960 is pretty engrained if you ask me…Ya know what would be cool? Colorado has a relatively uninspiring Rivalry Weekend opponent in the Big XII in Kansas State. Kansas has a totally random Rivalry Week opponent in Utah. Colorado and Nebraska used to always play on the Friday after Thanksgiving before Nebraska moved to the Big Ten, and Nebby fans STILL talk down about the fact that they "have to play Iowa," even though the Hawkeyes have owned them. Entitlement apparently takes decades of evidence to wear off, lol.
I vote Kansas naturally plays KSU on Rivalry Weekend, and Nebraska picks its rivalry with CU back up and has that as their Black Friday game every year. We then kick Northwestern to the curb and play them in October or something, and we then offer Iowa a home as our protected Rivalry Week opponent. All in favor say aye.
EDIT: The Northwestern last-weekend-of-the-year thing is not that engrained and pretty forced. From scanning Wikipedia, our final opponent of the regular season was...
