arkstfan,

You are not thinking like a P5 conference commissioner, TV exec, or college President. Very simply put, you do not add schools that do not raise your profile either athletically or academically. The biggest value of Oklahoma State is as Oklahoma's opponent in bedlam. Beyond that they are not much more an asset than say Purdue or Pitt. Not worthless by any means, just not worth a ransom. Apart from Oklahoma their value is dramatically less.

But there are other points. The SEC wants to remake itself, they have added two AAU schools, and an expansion will almost certainly mean they must add a 5th one. OU is fine, but OSU can't be the other. They also want flagships. Or as Frank the Tank puts it, only University of [State] need apply. The other problem is while OU would add Oklahoma, OSU would add nothing further, not many more TV sets (or whatever media we consider in 2025) and nothing more recruiting (a big point). The SEC (or P12 or B1G) would want a school from another State.

The only way OSU moves is as a package of 4 schools that includes Texas and Oklahoma.

As for the Hood-rich who worries about personal insult by Larry Scott to David Boren in rejecting his appeal to take OU and OSU, well, as JRsec mentioned David Boren is not likely to be around when the decision making is done. As Otto Biederman liked to say, "Nothing personal, it's just business"
