Let's be honest, do you believe the banner really mattered that much?
I mean, this is UT with big donor money. Another season like this and Mack Brown is gone as well.
If the UT offense couldn't score against KSU (or run the ball for 200+ yards), then the OC had to go. Heck, I think should be the measuring stick for any OC in the nation - whether you are at Chadron state or Florida State. If you coordinate the O and your squad didn't get the yardage and the 40+ points then you must really suck at your job. Your fired. No discussion. No exceptions.
