You would see something like that happening in rugby, the way he came down i mean. When a garryowen is kicked you have two players jumping up to try and catch the ball and they can come down dangerously. You cannot tackle the player when he is jumping. Still very dangerous though because like the guy in the video, when someone bumps into you at speed when you jump, their momentum can distort your landing position.
In rugby though they would be aware of what could happen so that may make it safer. As in they know it is dangerous when they jump.
