That's a good question. It seems unlikely they could get a game with a D1 team at this point but there are whole load of postponements/cancellations this week so maybe that would allow UNA to find a mutual opening with someone since they now have both 10/27 and 11/17 open. Even with 6 D1 games they're still only at 55% D1 games on their schedule so not sure it would matter much.
But, like you said, it shouldn't matter much. I think the only time it would come into play is if NDSU is right on the threshold of D1 wins needed for an at-large. The championship handbook says something like "any team with less than 6 D1 wins may be given less consideration for an at-large selection". So I hope it doesn't really matter. It if does Bisonville would've imploded by that point creating a massive black hole in the internet that would probably bring the entire world to it's knees.
