The fact is that GORs have been an extremely effective way for conferences to remain stable and prevent members from moving elsewhere. Look at conference movement before and after GORs have been signed. This can't be argued.
To my knowledge, member of a conference with a GOR in effect has ever even tried to leave.
That said, I do agree that when you get close to the expiration of a GOR, leaving becomes more realistic and possible.
The GOR for the ACC is further in the future than any other P5 conference. That didn't happen as an accident.
The only reason UT and OU are being discussed now is because the GOR for the B12 is getting close enough to make discussing leaving worthwhile.
With the reported interest of OU and Texas in moving to the SEC, here's a look at some questions about the logistics of such a move
