All the way from Italy. Coaches always tell us, always chase after a kick at goal, you never know what might happen. It could it the woodwork and bounce into the arms of an onrushing attacker for an easy try, or bounce to an empty space that should have had a chaser but they weren't bothered to chase up.
This example though, is quite different. It appears that his teammates have no faith in the kicker. They know that he won't reach the goals, so when they chase, they chase hard. And they get rewarded for their efforts.
