"Rugby doesn't have these problems because the fast non-stop fluid nature of the game means you can't tackle someone hard enough to cause the same level of damage because you have to be able to get up and run again right away."
Rugby doesn't have these problems because there are very specific rules about what constitutes a legal tackle and what doesn't.
You can't:
- Tackle a player without the ball
- Tackle a player in the air (e.g. a full-back going up to catch a high ball)
- "Lifting a player from the ground and dropping or driving that player into the ground whilst
that player’s feet are still off the ground such that the player’s head and/or upper body come
into contact with the ground is dangerous play."[1]
