Wow you really wrote an essay there. I’m no going to repeat it. I will say the only people thinking your way are obsessive rugby league tragics on Internet forums. No normal rugby league fan is going ‘I’m from Logan and Broncos are from Red Hill so I cant support them.’ It’s nonsense. People have 4 reactions: they like the Broncos, they hate them, they’re indifferent to them or they don’t watch league for various reasons. Dolphins are going to get their fans from the last 3.
You’re focused on a north vs south rivalry. Broncos vs Dolphins will be a neighbour vs neighbour rivalry. It will be father vs son, mother vs daughter rivalry. Households will be divided. That’s how you get people talking. In 15 years the Dolphins will be up there with the Broncos as a nation brand rugby league club. Even their new supporters will mostly forget that they came from Redcliffe. They won’t be view as a north or south team but as a Queensland team.
As for the AFL that you’ve got a hard on for, I’d pick the Dolphins as a brand over the Suns or Giants. Why? Kids like Dolphins. Kids, in particular girls, will follow the club simply because they like the mascot. Those are your adult fans in 15 years. Now compare that to asking a kid to explain what the hell GWS means and where it is…
