I guarantee you the other team is us.
I have just watchted Koshie on AFL 360 and it was suggested to him, in regard to the second team, that Gold Coast would be a good fit with tourism and Sydney would be good fit with property development. Koshie reply immediately suggested that WA was a good fit also due to mining interests. His first reponse was to say WA.
A bit later he was asked if he had spoken to any other club to lay the ground work, he replied that he has indeed contacted one fellow president of another club to be the other team, they have agreed and it just needs to be ticked off by the AFL Commission.
It is a WA Team. And that means us and I dont think its a bad thing necessarily.
