This is an interesting question.
We've already been across the entire spectrum of AFL clubs.
Adelaide: Big expansion team from a traditional Aussie Rules state other than Victoria.
GWS: Plastic AFL love child from a non-AFL with no culture or history.
Geelong: Big, traditional Victorian team.
I'm tempted to say the only feather missing from our cap is a really big Melbourne-based club, but they are pretty much all basket cases at the moment - Cartoon, Essendon and Collingwood all going off the rails. Even Hawthorn are cactus, not that I consider them a big Melbourne club (despite what their fans would tell you).
