Ok you want a hot take, here's the truth.
It has been so long ago since we routinely played the former Big 8 / Big 12 teams that I have no hateful disdain for any of those teams.
Even if this year we scheduled Oklahoma State, Kansas, Texas Tech as Non-Conf games for one season (insert any former conf team) it means no more to me than if we play anyone else.
Now, if I was living in Colorado, Kansas, Missouri, I may feel different. As a Texan, I don't have any hate towards UT or A&M or OU at all. None. Zero.
I actually watch their games if they are on and enjoy it.
