I saw a blurb that the 2020 Seahawks have broken the NFL record for air yards given up in the first 9 games of a season. Note that they are 6-2 having only played 8 games.
With a defense that porous, there's no worry about them going on a 8-0 run down the stretch.
The Saints only objective is to stay a game ahead of the Packers, who BTW cannot stop the run. With at least one game against a top running (Titans), the window to do that is there.
