If you were toying and playing vanilla defense all game long to try and "hide" something from Oregon, then I would hope we'd say enough is enough when Arkansas State is down 14 and about to score to make it a one score game within the final minutes. Then I would hope if Arkansas State gets the onside kick we would really turn up the defense to make sure they got nowhere close to scoring or tying the game.
IMO, the hiding playbooks to keep things secretive against future opponents is hogwash, and it certainly shouldn't and wouldn't apply when you may lose a game.
