I'd agree. With as much misdirection that gets schemed in today's NFL,tackles and guards need to be able to play both ways. How many teams play strictly drop back passing? Maybe TB? Do the Chargers (I have never seen Herbert play live, so I dont know what they do on O)? But going back the the offense in general, I think you are looking at Oline upgrades, RB help, and WR, but its a faaar cry from where this team was in week 2, or last year, or even 4 years ago. Justin Fields is just that good.
