Jap Rugby is no threat to the ARU .
Australian players are already there but only those whose international careers are over ... like George Gregan , Stephen Larkham , Nathan Grey , Toutai Kefu & Joe Roff ... because the selectors cannot pick someone to play for the wallabys who doesn't play for an Australian province .
It's not directly impacting on the ARU contracted Wallabies squad (yet), but the loss of RU players to Europe & Japan from Aust, NZ & SA is eroding the player depth of the Super 14 teams.
Sure some players lost to Europe & Japan would have retired if the offers weren't there, but by far the majority who have gone were still of a standard that Super 14 teams could well have made use of.
The NRL has lost players too, but that loss is spread over 16 clubs - Aust RU only has 4 Super 14 teams, and there has been plenty of admissions in the media since the Force came in, bleating about the lack of sufficient quality players to serve four Super 14 teams.
