Your arguement falls down because you don't know the facts.
The Port Adelaide Football club has been a contniual entity since 1870. It changed leagues, guernsey and emblem in 1996 to keep the whinging underachievers named Collingwood happy. Port have always been a successful football club. Eddie is fat. We are better than you. We are top of the ladder.
These are the facts.
So I enlighten you to why the Sydney Swans demand more historical kudos than Port Power and you come back with "Eddie is fat".
BTW...
Just had another look on the AFL website.
Still no information regarding Port Power, Port Magpies or anything Port prior to 1996.
And of course you've been successful.....Imagine how much more successful Essendon, Carlton and Collingwood could have been if they could have been playing Grand Finals against Sturt, West Adelaide and Norwood.
Geez, even St.Kilda could've snagged a few premierships in South Australia.
