Right....Texas is getting their way. This is the key paragraph:
"The Big Ten and SEC need inventory for their networks. That's part of what the Big Ten's expansion was about. The SEC has yet to play its hand in further expansion but is launching a lucrative network in approximately 15 months. The league might add a ninth conference game to add inventory for the network.
There is no market for a Big 12 network. ESPN/Fox own all the games except for one (nonconference) game owned by each school. Schools choose how to monetize those contests via streaming, pay-per-view, etc.
"You can't start a network with 10 games," an industry source said.
Especially with The Longhorn Network basically keeping Texas out of the mix."
