Has to be the Adelaide Crows.
Growing up in the 90s playing junior footy in Adelaide everyone followed the crows as Port weren't in the AFL at the time. When I played under 8s Tony Modra, Ben Hart and Nigel Smart came to our training session and kicked footys around with us. Can you imagine being 7 and having Godra hang out with you? Been a life long fan ever since. Season ticket holder, go to every home game I can and try to get interstate at least once a year. It's my absolute dream to be at a winning grand final which we were so close to last year :(
