I went back and watched some more to confirm what I thought I saw each week..
Watkins gets open, and there have been missed opportunities but sometimes Goff takes the safer throw, and that's fine. Watkins is our X and plenty of times he's on the 2 receiver side and often when QBs are asked to read one side it's the 3 receiver side, the strong side, so that will leave out some things that might go to Watkins if it were not a rookie QB, which Goff still kind of is.
But, as you say, they can use these "misses" later in season and they can be devastating, putting games away or getting out to a lead. I thibnk the concern about Watkins isn't that big a deal, at least not as big as it's been made in sub-media and boards.
Sure, I will offense were hitting on all cylinders now, but if he are hitting on 5-6 of 8 and are 5-2 I have no beefs
