On the theory of pushing your opponent to do something there uncomfortable with, I would strongly consider running a lot of jumbo 11 personnel today. Give me two right tackles, a running back, and trip wide receivers left.
I don't think Gardner is a full shutdown corner, at least not yet. But if they're just going to play him at left corner, make them pay to waste that position. Or put LJ wide right over there by himself a bunch, and have him block. See how patient Salah is if you're wasting one of his best players by flooding the opposite zone.
Not a major thing, mostly a mental game. Just force them to react to you.
