Sometimes people forget the most priceless quality in a rugby player. It can also be easily overlooked, particularly on sunny days in benign conditions when tries flow like warm honey. Even away from home in deepest midwinter, with sub-zero temperatures freezing your snot, it is only fully visible to those aware of just how deep certain individuals have already had to dig to be there.
