To me, it's no more putting a floor or ceiling on a season the way we all did this year with the 8-4 talk. Expect the best and let the chips fall - right now 12-0 is the goal until it isn't, then it will be 11-1.
We have no real idea of what the team will look like next year, whether it will be Milton or someone else at QB, how improved Milton might be after an off season with JH, what kind of impact players we'll find in the portal, how the young players will develop and step up into key roles, and so on and so on.
Instead of putting some sort of artificial cap on the season as a defense mechanism, hope for and expect the best.
