I agree, that’s true.
However I’d also suggest measuring based on membership and social media numbers is also in large part flawed as these metrics are largely influenced by on field success, in particular recent success.
100 per cent. This response is 11 years old but absolutely holds true. Its basically impossible to grow relative to the other clubs. The food chain is well and truly established
The huge differences in size of supporter base between clubs have been established over 100 years. They are not amenable to change in the short or even medium term even with "good management" or giving a club more funding to spend on projects. Similarly, in the newer states to the national competition, the first- established AFL clubs will hold advantage over their newer competitors for many decades and perhaps forever.
The 'size of supporter base' correlates with all club revenue sources – members, attendees, coteries and even sponsorship income. It is logical - if a club has four times as many supporters as another club, it is likely to have many more supporters among CEOs and marketing directors as well as among members.
Data suggests that over half of supporters follow their parent's team. There is little evidence that the relative size of supporter bases has moved much between clubs over the last 50 years. A few clubs may have lost a little ground after decades of poor performance and arguably only one club has gained due to a level of sustained on-field success 30 years ago that cannot be repeated.
There is even evidence that some smaller clubs have done a relatively better job than some of the larger clubs – such as converting a higher proportion of their supporters to members and often getting a higher yield per member. As well, some of the smaller clubs have achieved better win/loss records over the recent decades than have some of the stronger clubs and it isn't plausible to argue that they can do this consistently with inferior management
This is only reinforced by the way the fixture is structured and the commercial contracts. The huge surge in support for Richmond and Carlton in recent years show that on field success has little to do with off field strength.
