I don’t think anything changes unless Marcus starts to demand changes

You can put them both in the booth and it may or may not help. The root of the issue is we seem to default to schemes that do not fit our personnel and bull-headed determination to run plays and schemes that do not work (let’s run the fade for the 20th time). Marcus doesn’t have to be a jerk, but he has to insist on success. He mentions execution but he also needs to be saying it starts with coaches. This shouldn’t be happening in year 5. He built this team up as being his best but it hasn’t lived up to its billing. I’m more of a wait until the end of season type of person to evaluate staff, but this is tiring.
