One of the things I love about football is how connected everyone and everything is. You have a great line and it makes your QB better. Our secondary benefitted greatly from pressure up front. So a deep threat, a strong possession receiver that can get open quick, and a TE that can make the defense adjust will absolutely take some pressure off the line. This assumes Goff can play, but you have to make that assumption.
Reliable varied options that are credible threats takes away 8 in the box and that alone makes our line better.
