Chip Brown of Rivals (whom I usually trust) reports the Pac 10 is set to extend invitations to Colorado, Oklahoma, Oklahoma State, Texas, Texas A&M and Texas Tech to join the league and form a 16-team conference:
The thought is the Big 16 (or whatever they decide for the name) would start its own television network that could command premium subscriber dollars from cable providers on par with the Big Ten Network and pay out upwards of $20 million to each of the 16 schools in TV revenue.
If those six teams choose to join the Pac 10, it could affect the ACC should the SEC choose to expand to 16 teams as well. Without the Oklahoma or Texas schools available, the SEC could look to the ACC for teams to poach.
Stay tuned.
