Even when protections are good Jimmy G has a tendency to throw questionable balls. I would guess that Jared's vision is better basically, whereas Jimmy G has far more situations where he doesn't see or read things.

But both are in offenses where the QB is set up for success. Jared because of McVay's ability to utilize scheme to get him clean reads. Jimmy because of the same thing as well as a better OL and run game.

Shanny vs McVay I am of the mind that Shanny gets the edge because of that run game potency. But I also think McVay is a better overall head coach and over time that is going to prove out as he masters both sides of the ball and matures into a true rarity in being a head coach who has top knowledge of the full game.
