Rugby (both codes) is a fascinating example of how sports can get their on-field culture so right. There’s an implicit respect for referees, and when a man is down, he’s down for a reason.
Unfortunately, as is our way, we take our influences from English football, and worse again it’s combined with a cultural yearning and even respect for acts of shithousery, that borders on sado-masochistic; we will blindly defend one of our own when gouges an opponent, and blithely condemn one of them for getting upset about it.
It could take generations to reverse this culture. But the quickest way to get there would be to make sure that management and supporters always roar for their team to get back on their feet after a collision. Hence that suggestion for a rule change: if you need to see a physio, then you must be hurt. So you’re taking a full minute on the sideline while the game carries on.
