Do we?

The only thing that prevents the ACC from blowing up eventually is ND joining it full time.

If the ACC blows up, where is ND going to go?

Construct a new conference with no draw except itself?

Stay independent with a major inability to schedule anyone of consequence and high likelihood of being on the outside of any playoff system?

It will be a few years, but when/if the ACC self-destructs, ND needs to find a dancing partner.
