The usual big clubs have traditional support. Especially Collingwood, Richmond, Essendon, Carlton.Support there seems so even.
I guess people probably had a connection to the big historical clubs of the time. Add in the delineation of north and southern leagues and you have even more rusted on outlooks to football.
On bigfooty and in general, it just seems everyone has differing opinions on the big clubs there. And there's arguments for all.
Seems Richmond, Hawthorn, North, Saints have the most down there but you'd imagine that naturally Collingwood would too. The only side who seemingly have none down there is the Bulldogs.
