Yawn. How so, exactly? By starting their own network? One they approached A&M to do jointly? After approaching the conference to do a Big XII-wide network? By being a market and a brand that has brought millions to every member school in the conference?
Actually, Missouri has been creating instability in the Big XII for years by doing everything but holding out a "will give head for Big 10 entry" sign on the side of the road. But sure, let's blame Texas.
And what relevant rivalry has Missouri ever been involved in? They suck, they've always sucked, they're going to get their asses handed to them in the SEC, and their Texas recruiting pipelines are going to dry up. Good call Missouri.
