In any season there are 10 or so coaches and probably a whole bunch of part time specialist coaches, video analysts, stats guys and medical and fitness staff. We've seen what happens at a club like Essendon when there aren't clear lines of authority and honest communication between the different segments of a football club.
Our ability to bring new playing talent through the door is limited by the draft and free agency. Our ability to bring new coaches through the door is limited by who we are capable of recruiting in the offseason. In both instances, from about November each year, we can't really add new players / coaches to the mix. So attempting to maximise the coaches ability to communicate with each other and the players in any given year (until deficiencies can be addressed in the next offseason) seems like a good idea.
It also seems like a good idea that the person responsible isn't Lyon or Bond.
