Nice read there.... but I do think the SEC is just along for a free ride on this one, true as all of the above may indeed be.
Texas is scared of almost anyone with a winning tradition. They won't feel right until they've managed to position themselves as the leader among the little people. (Oklahoma excepted just for the sake of a little credibility -- they just don't seem to do well vs the Sooners historically... anyone notice?) That aside, they've bullied everyone worth a damn right out of the Big-12, if not on the field, at the bank which is probably much more painful... and they used deception and a Texas two-step to pull it off.
In other words, the fix is in. You can't be much more obvious about it than Texas has been... just look at how the Big-12 has morphed into what it has become over the last few years.
