To clarify- being that I don't know and can only guess as to how different teams design scheme/game plan wrt who has input and who's just implementing the plan on gameday w playcalls, substitutions etc...I think it's easier to make assumptions about who's doing their job and who isn't if you are talking about a coordinator vs a positions coach but not really any more likely to be accurate. imo you'd need to know the decision making hierarchy and I'm pretty sure that varies from team to team, I have no real insight into how the Bills do it so necessarily I don't think it's true that you can credibly judge the OC/DC as opposed to their position coaches
