Goff will continue to grow and improve. That's a great thing. However, I don't think you should expect consistent 350 yard and 4 TD games from him by the end of this season.
The rest of the NFL was not prepared for Goff to break out like this. They didnt' know what to expect from a McVay game plan. Partly because McVay modifies his scheme for the talents of his players. So....the two will offset each other. As the NFL gets its "book" together on Goff and McVay.....Goff will be that much more mature and will elevate his game. So, it's possible what you see is what you will get from Goff. To me....that ain't that bad.
