New Zealand and Ireland are the two best rugby nations on the planet right now, just as the Crusaders and Leinster are champions of their hemispheres (can someone, somewhere, please organise a decider).
But, perhaps, more importantly, the central contracting element.
With relentless demands abating none, it's clear only when national unions pull the strings is everything geared towards producing the best possible national team.
There is no other way.
That is professional rugby's pyramid for on-field international success.
In the saturated modern game, which now effectively runs every month of the year, this system paves clearly defined, carefully managed, rest and rotation across all teams, all levels.
This is imperative to remain at the peak of the pack.
New Zealand protects and preserves its leading players expertly well. Ireland, in a dictatorial manner, has followed suit.
South Africa, Wales and Australia are all desperately trying to cobble together more aligned domestic approaches.

Long-term, the truth is England and France have no hope regaining control of their players from all-powerful clubs and will, therefore, always play catch-up on growing welfare and fatigue concerns.
Rest measures announced by England last week are akin to buying a puncture repair kit from Poundland.
And with Jones unable to maintain the initial response extracted from an emotionally damaged team still reeling from the failure to progress from their pool at a home World Cup, it is probably now left to Ireland to put the strongest challenge to the All Blacks' mantle.
Not that you'll hear anything of the like from the men in black themselves.
No way in the Queen's name would they ever underestimate or overlook England at Twickenham. Their focus is always week-to-week.
For the purposes of this piece we can look forward, though.
And so the shame of it all is Ireland will be missing Conor Murray.
'What, that's it?' you say. 'I kept reading for that?'

Murray is, without doubt, one of the world's most influential rugby figures; his importance to Ireland greater than that of even Jonathan Sexton.
No disrespect to Ulster's John Cooney, likely replacement against the All Blacks, but Murray, considered to have surpassed Peter Stringer as Ireland's best halfback, is in another league.
For Munster, Ireland and the British and Irish Lions, he is superb; mixing poise and control from the base with a kicking game – deadly accurate box kicks – that often turns defence into attack. He also snipes regularly, particularly close to the line, and knows Sexton's play intimately.
No one player defines a team, but remove Brodie Retallick from the All Blacks and you then have an appreciation of his value to Ireland.
Murray hasn't played since helping guide the Irish to their first three-test series win in Australia in June.
Such is his importance, rumours were rife a troublesome neck injury could end his career.
Fears were allied, somewhat, when he turned down interest from the Top 14 to pen a four-year extension with Ireland, instilling his status as one of their highest earners.
He hopes to be cleared by medical staff to make his return with Munster sometime in November.
But given what will, by that point, be a five-month absence, it was too late to be considered for Schmidt's squad.
With the World Cup so close, why would you take the risk?
And, thus, while nothing is ever a given, Murray's absence is why the heavyweight showdown between the world's premier rugby nations tilts significantly more in the All Blacks' favour.
