Rules and Entertainment
I'm very positive about the product on the park and think rule changes that have been implemented are all about protecting players and reducing the ability of a good defence to snuff out attacking flair. I can watch division 3 Japanese rugby and be entertained by the ball handling plus investment in hybrid pitches has been a huge boon over the past decade. Playing on grass in soggy Glasgow wouldn't make for much entertainment. Yes, we can grumble about refs and squint feeds etc, but it doesn't detract from the sport for me too much. The NFL is as confusing as hell with rules and it is lapper up.
Leagues
I think the main leagues and participants are all good, including the Tier2 pro leagues (albeit these are not yet financially sustainable). Salary caps are great. The English league shows the way in TV deals mixing TV money and some accessibility via some free coverse. The Challenge Cup needs to find relevance (I'd suggest by mixing with Tier2).
Internationals & Politics
So far so positive. So why does a guy who loves his sport and thinks rugby rules are contributing to greater entertainment have lower interest than at any point in decades? We have professional players playing outside the 6N and RC who are offered meaningful fixtures in an intense atmosphere once every 4 years (if they are lucky). We have Tier2 access to the Challenge Cup withdrawn, Jaguares kicked out of Super Rugby, no real effort to retain the Sunwolves.
Clubs, Tier1 unions and World Rugby all appear to consider incorporating professional sides from Tier2 into a pathway leading to the top table as someone else's problem and realistically will only ever consider it if there is short term financial gain (Super Rugby Pacifika excepted). When you mix warm words with treating others with barely concealed contempt you leave a bad taste.
Political gains like the San Francisco agreement to increase Tier1 vs Tier2 fixtures are welcome, but fall far short, being a bunch of friendlies. Bizarre favouritism of the PIs and NA in terms of Tier1 tests continues. November and June tests remain friendlies including tedious three test affairs of no import except to die hard fans.
The attempted coup of World Rugby by SANZAAR failed, leaving those allies split. Argentina barely have a pro team and NZ and Aus in particular are going to lose out to NH leagues in terms of player wages, with knock-on impact onto international performance. SA is fairing better, but what if the TV money runs out? Will the welcome mat be withdrawn by the NH?
We are seeing mad things like World 12s, or Georgia sending sides to the Currie Cup all because certain unions have literally zero interest in the long term international health and growth of the sport if it means investment over the short to medium term, or any kind of short term sacrifice of any kind whatsoever.
Player development and eligibility
Eligibility rules are exploited by some to such an extent that youth development is a fool's errand. Scotland now has less than 10,000 active adult male players, because it is far harder to spend 10 years developing a kid to a professional adult than it is to check the family tree of a player developed by another union. Yet the Scottish union is considered a well run union that has improved international and club performances. The move to 5 year residency may make things less farcical for the neutral by 2027 though.
Suggestions
Trying to be politically realistic I would like to see a move to something similar to international cricket's world test championship. In short, make the international windows count but also (unlike cricket) provide relegation and promotion.
Whether you play a one off test or a test series the results goes to your international score. At the end of the 2 or 4 year cycle the top 2 or 4 sides face off in a playoff. With such a format over 3 divisions of 10 teams (with promotion and relegation playoffs) the June and November test windows become meaningful and permit theoretical access top flight rugby for the top 30 ranked nations in the world. All without impacting on the 6N or RC.
Combine this with restoring a link between the EPCR tournaments and the Rugby Europe Super Cup or Tier2 professional European leagues and many of my grumbles disappear. But really, we are in a situation where the Japanese league is buying World Players of the Year and still none of the suits in global rugby invite them into a meaningful international structure. I'd call it incompetence and short termism at best. If moneybags, World Cup hosting quarter finalists are excluded, what hope for any other of the 100+ Tier 2 or 3 nations.
As Tier 1 fans this may not be considered all that relevant. But the integrity of a sport relies on people being able to access it regardless of nation, wealth or social standing. Rugby is abysmal on all three of those counts in my opinion and with the growing weakness of the SH the global game could be on the cusp of a significant downturn. If Aus, NZ, SA or Arg should have a wobble, who has been nurtured and cultivated to take their place? Nobody.
