Something the Cowboys did last week should be replicated. Just play Diggs and Bland and use ALL of the safeties. I want Wilson, Hooker, Kearse and Mukuamara on the field at ALL times. I do not think this is a good game for Anthony Barr- Damone Clark should just stick to whomever is in the backfield.
I want to see a lot of safeties keeping an eye on Purdy who will take off to run, but they need to STICK on the YAC. If SF is going to beat you, make them beat you with Purdy throwing it deep/intermediate, not with McCaffrey and Deebo running everywhere or Aiyuk getting open on slants for 7 yards over and over again.
And most importantly - don't eat the cheese. SF will use Parsons/Lawrence momentum and aggressiveness against them. I think they take Parsons out of the game by making him eat cheese. Nobody else. Personally, this is a game where I feature Parsons off the ball a lot more than at end. Let Lawrence & Williams/Armtrong rush from the ends and sent Parsons to work against the guards.
