I'll say the unpopular opinion.
If I'm the AD, I evaluate the situation after the season is over, whereby the main criteria is "are we better positioned for success now than prior to the season?"
That considers the final record and any post-season performance. That considers recruiting and roster health. That considers development of players. And that also considers expert opinions (no, not ones from the Boneyard). I would be talking to Calhoun, for sure, and other people in the field.
And thankfully, I suspect that Dave Benedict will do all of those things and behave accordingly...
