Texas will get it rolling again in that conference, eventually, either now or later. They have too many advantages to stay down for too long.
To me it looks like OU is living on borrowed time. They have no defensive identity any more, and, I assume part of that is that the recruiting landscape has made it harder from them to recruit top notch defensive talent (some of you guys that follow recruiting more closely can correct that if wrong). That's a self perpetuating cycle, and not easy to get off once it starts, as we know too well.
TCU and Baylor will revert to what they've always been - no reason to expect otherwise.
Tech will never be more than a spoiler.
WVA just lost their head coach to U of H, and might have trouble getting an equal replacement.
K-State will go back to what they were without Snyder, and KU and Iowa State might have two good seasons in 20.
OSU and OU are the only viable long term challenge. I think OU will decline and OSU seems to have a ceiling. So, the sips are largely going to have their way with that conference.
They're our number one in-state rival, and they have an easier row to hoe on a built-in basis. Before it's all over, it's going to be a real drag to not have them on the schedule.
(I note that Georgia accomplished something while I typed this - too little, too late.)
