What happens if all four teams are unavailable???

While that scenario isn't explicitly spelled out, I imagine National Championship will be "vacated" for that. Obviously, this is what I am rooting for, and what the stupid CFB playoff system deserves. Would be ok with every team but Cincinnati going out, that would be pretty funny too.

I thought "vacated" too, but found it interesting that the document didn't note that possibility.   

I would prefer the SEC teams not win.  However COVID loves people spending time indoors so I would have guessed Michigan and Cincy are the two teams more likely to be impacted by COVID issues prior to the semis.   I think Michigan has done the right thing for themselves, their state and the USA.   Get everyone boosted.  No excuses.  No delays.   And for that reason I hope Michigan wins.

Michigan vs Cincinnati would be my preferred match-up
SEC (unable to play) vs SEC (unable to play) would be my dream outcome should both SEC teams reach the CG.
