Its a bit narrow minded to think that you could survive playing ALL your games in Geelong. Yes, in the short fall you gain some home ground advantage and maybe a few wins along the way but you also restrict the growth of your supporter base. How can you increase your membership base when the only access you have to the ground is a 30k stadium? Your Melbourne based supporters will drop off. Revenue from sponsorship will drop off accordingly etc. And to top that, during the periods where you aren't as successful as you have been in the past decade, the whole situation only gets worse!
