<span style="font-weight: bold;">so could someone explain the effect of the TX and OK schools joining the PAC? </span>
No effect on us. We didn't want Texas and there was little chance we were going to get OU because they have to come packaged with OSU. If it happens it just forces the super conference scenario we all expected to play out over the next few years.
<span style="font-weight: bold;">How does the market share of this affect the SEC and how solid is the SEC's standing as the top conference?</span>
Again, no effect. This is about TV. We aren't looking to corner the market on Texas teams, we just want to get in the door and Texas A&M does that for us. OU, if they wanted to come to the SEC, would be considered because what they have achieved but it's not the best TV market. I think Missouri would be our target so we can get the Kansas City and St. Louis markets. The SEC is the best not because of the number of teams, but because how much our fans care about the conference. That won't change.
<span style="font-weight: bold;">Is the Big 10 any threat to our overall influence?</span>
None at all. The Big 10, even post expansion, is still the 3rd string conference. There is nothing they can do to pass us or the PAC-12. Dominance will probably pass back and forth between West coast and East coast till the end of time.
<span style="font-weight: bold;">Will there always be an SEC or is a Big 12 breakup a possibility?</span>
There will likely always be an SEC. The Big 12 was so centered on a single state that cannibilization was always an issue. You also had Texas, who are the biggest bunch of cocky pricks on the planet. So much so that they demanded more money than the other teams. I think for a lot of reason that won't happen int he SEC. First, total dominance is nearly impossible in our league. And it's also not our culture in the Southeast to be that kind of dick. We believe in fairness and we aren't looking to screw our fellow teams. I think the 10 original members keep the core of the SEC strong and as long as we find teams that fit in (so far we have done an excellent job) that should not become an issue.
