rivalry. OU has dominated this century. Texas dominated at times. especially in the early days of college football. but both agreed to not leave each other once getting in the same conference. both work together to keep the tradition alive. in fact there’s a bunch of money being put into the cotton bowl to keep the RRR there for another decade plus. it’s not toxic. at the game last year, there were lots of middle fingers and chants, but everybody was still nice and respectful to each other. it’s a great rivalry. byu-utah is a toxic rivalry because of utah.
