The long-proposed global rugby calendar would go a long way to bridging the skills gap between the northern and southern hemispheres.
As it stands, only the international windows in June and November allow for intra-hemisphere games; with either hemisphere unavailable for the rest of the rugby calendar.
While matches between European clubs and Super Rugby franchises would be the most obvious result of a potential global rugby calendar, it's far from the only positive to northern hemisphere rugby.
At the moment, the biggest difference between the two hemispheres is the time internationals spend together. In the northern hemisphere, there are three separate squad meet ups throughout the year, with a maximum of two months together during the Six Nations. Conversely in the southern hemisphere, international teams meet up after the Super Rugby season, and don't break up until the end of the year. That's a full continuous five months that allows for better continuity and squad harmony.
It may seem like something small, but at this level of professionalism the benefits of staying together as a squad instead of going back and forth between club and country would be significant.
Imagine how good Ireland could be if they were under the tutelage of Joe Schmidt for four continuous months, instead of three separate hasty lead-ins?
There would be less conflict between clubs and countries over where the players are meant to be at a certain weeks if the club window and international windows would be completely separate.
It's ironic then, that the biggest opponents to any change would be from this hemisphere.
The first is the 6 Nations. The easiest way to have a universal calendar would be to bring the sport's oldest international competition in between the existing June and November windows. Of course, this is going to be met with fierce opposition from traditionalists.
Another is the length of domestic competitions. The Pro 12 and the Premiership are both 25 match days long, with Top 14 needing 29. That would be over seven months without any break.
There's barely enough time in the year to allow the calendar as it is, but any changes would need the domestic leagues to reduce. This is also going to get fierce resistance, especially from the French who generate so much income from their Top 14 that they are looking to expand.
