On the face of it, looks like SANZAAR has got the better part of the deal - shifting June tours into July.
It will mean different things to different unions in the Six Nations.
There was a lot of discussion around the holding of the European final and that it should be the finale of the European season. McCafferty seems to be getting his oar in early by saying the Premiership will finish last.
Besides that, the PRO12 plans to shorten its regular league season anyway, reducing from 22 to 18 weeks with a two conference structure from 2018/19. This will take games out of the international windows. The season will now start in late September following the decision for new season end to be in last week of July.
The European Cup pool stages will be run en bloc during December and January. The English and French clubs want the Six Nations compressed to six weeks instead of seven to suit their revised season.
A new British & Irish development cup competition could emerge during the 6N test window replacing the dead duck Anglo-Welsh cup. This would feature the academy players from the 24 senior teams in the two leagues. The current B&I Cup would disappear or be reduced to lower club level.
The aim was supposedly to reduce player fatigue and number of matches.
Still not sure if that will be the outcome.
