Everything you’re talking about comes down to good governance from the game’s governing body. Rationalising grounds to the extent that the AFL has wouldn’t work for Sydney, but that doesn’t mean the NRL couldn’t be aiming to get Roosters/Rabbitohs out of a good Eastern Stadium, Tigers/Eels/Dogs out of a good ANZ refurbishment or partially out of Parra, Sharks/Dragons out of a southern stadium with upgrades to Manly/Penrith/Parra. That’s just an example, there’s been practically no governance, no lobbying, no vision, just ad hoc garbage.
Even absolute joke situations like the North Sydney district still existing doesn’t get an iota of attention from the governing body. It’s a situation that could have been remedied years ago with direction and governance from the NRL.
The AFL only forced those moves because the clubs weren't making them themselves... So if you are looking for bad governance then start with the clubs, because that's where the real problems are.
The NRL shouldn't have to force Wests to pick one home ground/region/market and stick with it instead of trying to be everything to everyone, they shouldn't have to pressure Manly to make moves to move out of Brookvale when it's obvious to any neutral observer that the joint simply isn't up to NRL standard anymore, etc, etc.
If the clubs were even half decent businesses they'd look at their bottom lines, see there were problems, do market research to identify the problems, and then move to address them to the best of their ability. That doesn't happen at most clubs in any significant manner, and it's ridiculous to suggest that that is the governing body's fault when in reality even if the NRL did try to do anything to correct some of those issues it'd cause open rebellion in the NRL because they don't have the power to push for change that the AFL does/did.
BTW, the irony of you agreeing that the NRL should move to more shared stadia but not for your beloved Manly isn't lost on me, and is symptomatic of the problem with a lot of clubs and why they are struggling.
The AFL have shown that clubs don’t need to have rebranding forced on them to succeed, just good marketing and good governance for the overall direction of the game from the game’s central body.
I gave you two explicit examples where the AFL pressured for/forced rebranding to help clubs become more sustainable.
Footscray - Western Bulldogs.
Brisbane Bears - Brisbane Lions.
Hardly, two of the worst performing Melbourne AFL clubs are the generically named Melbourne and North Melbourne (barely anyone outside Melbourne or the AFL world would be aware that ‘North Melbourne’ refers to a specific suburb, not a large northern region). It goes to show that success has many more factors than the club’s name.
Firstly, Melbourne and North Melbourne aren't 'generically named'. Their names refer to specific regions of the city, literally Melbourne's CBD and as you say the suburb of North Melbourne.
Secondly, neither of them are struggling because of their brand. They are struggling because they are from areas with large amounts of demographic change and are also effectively hemmed in by bigger competition with no room for them to naturally grow into. In other words they are like a few of the NRL clubs in that they are stuck in small regions of the city and surrounded by bigger, stronger, more well financed competition, and have struggled to grow beyond their boarders because of all sorts of reasons.
That wasn't a problem for Footscray, they had space to grow west, but if it was going to work they needed to make changes to appeal to the market, i.e. rebrand as the Western Bulldogs and heavily market in that area.
Manly could do the same in North Sydney, but it isn't going to work unless you are willing to sacrifice to make it work, and that is where the problem is because you aren't willing to make the sacrifices necessary, as this whole conversation of you starting with the conclusion that Manly can't/shouldn't change in any way and trying to rationalise that position post hoc proves.
Can't say I blame you for that position either considering that the club it's self probably reckons it can scrape by on it's grants, and that if the worst does happen that the NRL will find a way to bail them out like they do every failed club despite claiming they won't save anymore. So there's no incentive to improve, so why bother.
