There does seem to be an assumption that all players go to the NRL for the money but I’m not sure that’s always the case.
The opportunity to live a different lifestyle and to gain the experience of testing yourself in the NRL must also be a factor.
The advantage of going when you are young also means you are likely to be free and single without having to relocate a family.
A 3 year deal with Huddersfield sounds pretty good to me.
