If you don't play competitive senior football, and you dont have kids playing with the Club, not much will change.
Your coach and manager, if you have one, will get the opportunity should they choose to do so to work with a more supported group of coaches which will make their life easier and potentially help your team. You will see some new people, and may see a change in playing strip, some new names and signs around the Clubrooms and so on. That's about it.
At a higher level, this will make the Club more sustainable, which ultimately it isn’t at present. However if you do step back and look at the bigger picture, you will be in a position to have more pride in a Club that starts achieving more at the premier levels, or is doing a lot more to engage with its community to help people enjoy the game.
