Nebraska, makes sense on the map, but Nebraska would sooner slit their wrists than go back.

Clemson, FSU are pretty locked in to the ACC, and long term might be thinking SEC.

I actually think Arkansas might be most likely, but even that is far from likely.

Of course I'd love for any one of those to be added with BYU (as long as it's not two of those and no BYU), and the B12 will certainly check interest. But I agree with you that BYU and G5 is most likely.
