Rugby is 15 aside contact sport. The aim of the game is trying score on the opposition's territory ( TRYLINE) You have a back-line which obviously marks the back and makes sure that the opposition does not score, and you also have forwards who gain metre they are like the workhorses in the team. But the back-line controls all the fancy plays & moves. Rugby is a highly paid sport for the All Blacks anyway. Black Ferns get paid heaps but not as much as the All Blacks.
