In sport, injuries happen. When they do, time matters. The moment injuries look like they could be happening, you stop play, you tend to the people who could be hurt.
How long is long enough to leave people in pain? 30 seconds? A minute? Ten? 20? An hour?
I don't really care what everyone else thinks. I know that the welfare, health and safety of human beings is more important than how a game progresses. If you value a game over the health and safety of people, that is your loss. I think that is sick.
