The following players were replaced after the first round of games.
Samoa: Alamanda Motuga for Afa Amosa
Scotland: Magnus Bradbury and Henry Pyrgos for Hamish Watson and Ali Price
South Africa: Thomas du Toit for Trevor Nyakane
France: Pierre-Louis Barassi and Cedate Gomes Sa for Wesley Fofana and Demba Bamba
Tonga: Latiume Fosita and Fetuli Paea for Kurt Morath and Nafi Tuitavake
Wales: Bradley Davies for Cory Hill
These changes make the figure look like this:
There is one less unattached player, Nafi Tuitavake has no club listed while Fetuli Paea plays for Tasman Mako in the New Zealand Mitre 10 Cup. The unattached players left are Canada and the US (5), Samoa (4), Fiji (3), Georgia (2) and Italy (1).
As nothing has changed with Argentina, Jaguares have the most representatives with 26, followed by Welwitschias (20) and Benetton (16). With regard to Benetton, they already had 16 and I made a mistake in the original calculation. Benetton are alone on 16 because Glasgow lost a player when Ali Price had to withdraw.
Samoa remain closest to the centre and London Irish are still the club team closest.
Looking at the total numbers of all players named in the squads up to the end of the first round, that diagram now looks like this.
The following teams have named replacements since the original squads were announced: Samoa, Scotland and France (2), NZ, Canada, Fiji, South Africa and Wales (1). Like the 2015 World Cup, Samoa and one of the teams in the group with them have added the most players (so far). Not sure if France have just been unlucky.
In this diagram, Samoa are the closest to the centre (just, it’s very close with Fiji) and London Irish are the club team closest to the centre.
