Ground up engagement is important. Manly getting into schools, RL carnivals etc grows the brand recognition and association that the Sea Eagles are the area's team from a young age, that's why the junior districts and access are important.
I'm sorry but this is just utter BS mate.
You don't need control over the Bears junior system to market yourself in "Bear territory", and even if you did have control over their district it'd make little to no difference in your ability to convert people in that region into Sea Eagles fans.
What if Manly starts pouring money into the area, despite the Bears not giving them permission to link with their clubs etc, the Bears whiteant whatever efforts Manly makes and 10 years down the track the NRL says we're bringing in the CC Bears who also cover the North Shore? It'd be money down the drain in a big way. Any big investments in the area need to be made with clear air, the murky environment and lack of direction on the area's future doesn't encourage any investment- it just leads to what you see now.
What would happen is you'd have spent ten years building a fan base that isn't going to care less whether or not the Bears exist, and if you continue to market yourself in the region you'd continue converting fans in that region whether or not the Bears exist. Adding the Bears would just be adding another competitor to the market, and no matter what you do there'll always be competitors in the market, so maybe you should stop worrying so much about what those competitors are doing (especially ones that don't really exist) and worry a little more about what you are doing, which currently is absolutely nothing.
As it is it's incredibly unlikely that the NRL will bring the Bears back at all (let alone in NS or on the CC), and if anything the sooner Manly makes an impact on the broader NS market the less likely it is that the NRL is going to be willing to risk bringing the Bears back. So really the Bears are, or rather should be, a total non-issue.
Beside, the Bears folded their CC bid to "pursue other opportunities" years ago now, so really you've just got a fear of ghosts.
You're describing exactly what was wrong with the Northern Eagles. They adopted a bland, generic Northern identity that tried to appeal to everybody, but appealed to nobody.
Firstly, the Northern Eagles was a completely different scenario to what is being discussed.
Secondly, how could anybody possibly know that the Northern Eagles (specifically the name it's self and not the whole chimera merged Sea Eagles and Bears brand) wouldn't work, it wasn't around long enough for any real change to happen.
Whatever the Dragons have done wrong has little to do with their name. Angry Steelers fans would still have been angry if the merged team had a generic Southern name. If they've done a poor job with development and engagement down there, they wouldn't have magically done a better job if they had a generic Southern name. I'm not suggesting we copy their model or whatever else they've done, I'm just pointing out that the Manly name doesn't need to go, just as the Saints name didn't need to go. You're right that it's not a merger, which is even more reason why Manly doesn't need to lose the name 'Manly' if we also cover the North Shore.
This is just a giant straw man that I really can't be bothered addressing as it's literally got nothing to do with anything.
