I don't remember any specifics of that game, though I did watch it. It's not uncommon for a defense to take away whatever they think stands to hurt them the most. So guys like Mike Evans draw double coverage all game, and the scheme makes it a better option for Brady to hand the ball off, or throw it elsewhere.
Could be nothing more than that.
Saquon Barkley didn't really have a Saquon Barkley game yesterday, but that wasn't a knock on him as a RB. Just that the Chiefs said "You have to find another way to beat us." (which, they did.)
