This is a valid point it is always good to have someone willing to challenge you and potentially force you to look at something in a light you had not considered. Too many Yes men can certainly create predictable outcomes. Whether or not all we have are yes men or not I have no idea honestly.
However, I think he predictability of our offense is more likely due to personnel more so than a lack of differing opinions. It was much easier to be unpredictable with a top flight O line, a rb defenses were terrified of in Gurley that demanded them to respect the play action, and a WR who‘s speed commanded respect. We are limited in what we can do because of what we have on the roster currently. McVay and CO have done an amazing job remaining competitive while losing those players but I think as fans we forget that you can’t just lose Todd Gurley and not feel it. You can’t just lose a dynamic option like cooks and not feel it. You can’t just lose a pro bowl guard a solid center And have an overall worse o line where one of the best used to be and not feel it.
