This is misleading shit - in wafl there were two teams based in Fremantle therefore naming afl club after one would alienate fans of other. In Morton Bay there is & has only ever been one top flight team. In fact only professional sports team in area has ever been Dolphins.The only people that care about the "good" are already fans, and in the Dolphins case there aren't enough of those fans to support an NRL club on their own. So if the club is going to be the success it should/could be then they have to attract new people in, and you don't do that by running out in a brand that huge portions of those potential new people have been conditioned to hate.
You are also conflating support that has been gained through mass exposure over generations with people supporting a club simply because it's a "historic" club.
The Dolphins haven't really had that multigenerational mass exposure, and what they did have of it would have largely been lost in the previous 30 years. But even if they did have a bunch of supporters in the countryside they don't really need a bunch of "supporters", they need steady customers, and the vast majority of a clubs' steady customers come from their immediate region.
Sorry but I'm not trawling 30 year old newspapers looking for articles.
But anyway, the Dockers were initially announced as the 'Freemantle Sharks' until people threw a massive stink over it, I'll let you figure out why, and Port, or rather their potential fan base, argued over way more than just the colours, they argued over the brand, they argued over the badge, they argued over whether or not the club should be called 'Port Adelaide' or if it should have a more inclusive name, they argued over whether or not there should be a magpie on the jersey, and probably a bunch of other stuff that I'm forgetting and/or didn't hear about.
Proponents of Adelaide, Perth, NT wherever don't want this bid because they know Brisbane 3 is next.
Among NRL fans Dolphins are favorites
