Texas is definitely toxic, but in the original Big 12 Nebraska and A&M were every bit as greedy, selfish, and toxic, and again, Texas's toxicity isn't all that relevant if no one else is willing to dance with them.While I agree with this comment I also think OUT should be taking an equal amount of the blame in that one, more Texas than OU but everyone knows how toxic Texas is.
That's where the SEC takes the blame. They could have just said "nah, we don't need your drama". But they wanted their money, so here we are. That, my friend, is the definition of greed.
