Rugby has gone through a number of changes since it turned into a professional sport 20-odd years ago.

We've had the inclusion of video technology, the inaugural Heineken Cup, and a huge increase in TV revenue and the ease of watching the games. But none of these come close to the magnitude of the improvements made to the physical side of the game.
