Everything comes from the perspective of, if something is wrong, it can't be Goff's fault.
Well, not knowing that the sun rises in the east and sets in the west is not Fisher's fault. You're more annoyed at a coach for allowing that to be aired than Goff for not knowing one of the most fundamental facts any adult human being that's spent any time on Earth should know. Similarly, you should consider it may not be Fisher's fault that Goff doesn't know how to play QB in an NFL offense yet if after 21 years he still hadn't figured out how a day works.
How does it not occur to you that if Fisher were busy playing editor for Hard Knocks in order to undermine Goff's image, it runs completely contrary to his current Where's Waldo game with Goff in the media that's intended to blunt perceptions that he's not ready?
