How likely do we really think this is though? Calzada is your likely starter at QB. The OL is back but weren't world beaters by any means. We lose Zakoby, Smoke and McCreary on defense. WR is a black hole.
Then you have the recruiting. It wasn't good before, even though it was his bump class which is usually a coach's best recruiting class. After this, I don't see any way we can maintain from this year's sub-par effort, much less improve.
If you aren't sure you're gonna fire a guy or not, don't cut his legs out from under him. He is done at Auburn sometime in the year 2022, and his buyout is only $4m less after this season.
