Again, going behind Texas' back doesn't get you the crown jewel but instead gets you a bunch of team you never should have wanted anyway. OSU does not have a bad athletics program but they certainly don't bring anything to the table like a significant market, etc. And without Texas to play against, they just kill their own recruiting as half their roster is from Texas every year.
True, but I see why they're doing it. If Texas, A&M and Tech "want" to go to the Pac 10, w/o Baylor, and the Texas lawmakers block them from doing so because of Baylor, then that would be a very unpopular move, politically speaking. Especially since Baylor doesn't have near the alumni base in Texas as do the other three. They're putting the Texas lawmakers in a very precarious position, if all this is true.
There may also be stipulations to an invite to OSU, such as "if the remaining 4 come along", otherwise it's voidable. Even if the Pac 10 doesn't get the Texas schools, they can still get OU, OSU, CU and someone else, and probably still be happy. It appears there's a lot of political posturing going on. Fact is, the Pac 10 can probably act much faster than the Texas legislature can.
