Normal people work until they are 65, the average rugby player is able to play rugby until he is what, 33 or 34?  I am not sure of the pension situation for rugby players either but I can't imagine it is that great.  The guy needs to maximize his earning potential while he is still young as he is getting to that age where a rugby career can end in a heart beat. 

He is looking after his family by moving to France due to the following:

1.  He will be playing less games

2.  He will be travelling less

3.  He will be earning more money

Sounds like a good deal to me.
