Just on this bit, when we were winning a flag every 7 odd years, with a genuine finals run mixed in between, it was definitely not boring.
It’s not like the recent Hawthorn/Geelong eras where their club supporters supposedly switched off because of how good they were.
Not saying you have to win the whole damn thing all the time, but making a good repeat finals tilt even semi regularly probably enhances the emotion and belief. Say maybe once a decade.
It’s no coincidence that many long suffering clubs have low supporter bases and had extended periods at the very bottom, St Kilda a prime example.
I may have the rose coloured glasses on but I don’t think our supporter base would take success for granted or drop off that badly. More recent history does back it up though ie 2000 era don’t think we became bored and saga period we didn’t jump ship in the droves expected.
