The suburban grounds obsession is short sighted.
1) Expecting the state government to upgrade suburban facilities for the use of a single NRL club is a fools game. They are upgrading the big central stadiums, which are all in use by multiple clubs across 3 professional sports as well as major international teams and pop music concerts, and are major tourism attractions.
The suburban grounds are run by suburban councils and are basically the responsibility of local government and the NRL clubs that use them.If the State government upgrades them, it's only to buy votes, which may still happen of course, but I wouldn't hinge a club's future on it. Brookvale and Leichhardt are Exhibits A and B - no votes are swinging on them, no upgrades.
2) 20k capacity suburban grounds put a serious cap on a club's earning ability. Fair enough no one is doing a great job of exceeding that now, but we should be looking at decades down the track, not doubling down on mediocrity.
I'm not saying clubs should abandon suburban grounds, but every club has to have some big draw games that can smash through the 20k barrier. There's no hope of this if you play 12 games in the suburbs.
Parra, Wests, Bulldogs, Roosters, Souths stand to gain a big advantage as the central stadiums re-open in their new and improved forms.
If their average crowds start to grow past the 20k mark and beyond, how does someone like Manly keep up? Even IF Brookvale gets some decent upgrades it's still capping their ability for growth.
