I think the high tackle crackdown is obviously targetted at making the game appear more palatable to the mums and dads in an attempt to increase junior participation and I would say that is desperately needed if there is to be longevity for the game.
The 6 again rule appears to be a reactive off the cusp rule by an egotistical moron in an attempt to appease his NSWRL media overlords... Kunt is all about introducing fatigue back into the game to 'bring back the little man', because our best players in recent times have obviously been the NAS and Junior Paulos of the world rather than the JT's and Lockyers who weren't allowed to showcase their talents previously.
From a strategic point of view (if that even exists in the NRL outside of MOAR QLD TEAMS!!), I think the market they are trying to attach themselves to is the NBA style.
NBA is hyper athletic, skillful and is offense first with highlight reels galore, but is effectively non-contact and therefore doesn't rely on brutality or physicality (except at the rim).
I'm no longer young, but it seems the youth of today are becoming more and more attracted to NBA and basketball, far more than any other 'international sport' (football/soccer, NFL, NHL, baseball, etc.).
If you watch an NBA highlight reel on youtube you would think it's all dunks, 'breaking ankles', 3 pointers and buzzer beaters... but it's actually a serious grind with tons of fouls leading to free throws and timeouts halting play for minutes at a time. A good shooting percentage is above 50%... so on a good day only every second shot will actually go in. However, NBA players are fast becoming celebrity status and you can often see NBA jerseys throughout the city.
Despite this the NBA has a huge following even though it's only moments throughout the game that are actually spectacular (I think their popularity can be largely attributed to video game simulations and most notably the NBA 2k series, but that's a different post altogether).... but getting back to NRL I think they certainly have the product to match up with the same characteristics as the NBA highlight reel style, if not be more suited to that style of entertainment, as our whole game is non-stop and hyper athletic all the time.
I think with proper marketting the NRL can definitely survive on the athleticism and skillfulness alone (i.e. moving away from the brutality and physicality)... but does it end up becoming more like OzTag? Yes... but it will improve public perception and junior participation, which ensures the sport survives in the future.
Where the NRL are seriously failing at the moment is their game is not staged or positioned properly to tap into the kids. Only 3 games a week are on free to air TV and 2 of those games are after 8pm (most kids are in bed or going to bed by then). Across the whole weekend there's typically only 2-3 day games (Saturday 3pm, Sunday 4pm and sometime Sunday 2pm) and only 1 of those is on free to air... that is not accessible when you want to tap into a young demographic.
Looking quickly at the AFL it appears they don't typically have a Thursday game and only one Friday game, 3/4 Saturday games appear to start before 4:30pm and on Sunday all 3 games are before 5pm...
@Sproj would need to confirm if that's typical scheduling, but if it is then it looks like only 2 games a week on average are after 7:30pm!! It's also well noted that NRL looks the best when it's played in dry sunny conditions instead of dewy and slippery conditions, but the broadcasters have steered NRL away from that through scheduling.
I think the NRL need to seriously resolve the scheduling issue before they tinker too much with the rules.
They need to ensure the kids are devoted and participating in the sport before they lose their existing 'adult' audience... If the game moves too far away from what the adult audience want too quickly then they can lose interest in the sport and just cancel the subscription before it's ingrained in the next generation of kids (who are finding it harder and harder to watch or play the bloody sport in the first place). However, it's pretty bloody hard to say no to the kids and cancel the subscription if they are devoted to the sport.
An adult may lose interest in the sport if it's no longer what they want, but if the kids want to watch it every week, are participating in it every week and it's easily accessible (i.e. day games), then I think you will find that the parents will keep the subscription, because it's in the best interest of their kids to keep it.
