I chuckled at this Erik McCoy quote from a NOF Article

I think too much was put on the vets in the lockerroom to do that. You could potentially get away with that if say Drew was still QB, because his ability to hold people accountable translates. I don't think Carr holds that level of weight as a person, which is why he's better paired with an OC like a Gruden or at this point Kubiak who is a STRONG voice that's also respected. That way the players can focus on playing rather than holding their teammates, who are also grown men, accountable. Something the coaches in theory should be doing the majority of anyway
All of that is true and speaks to the whole concept of “chemistry” you hear people talk about when it comes to any team sport. Human beings working in tandem with one another is literally like working with chemicals under a microscope or a test tube.
