There's an ELV at the moment in schools rugby outlawing jumping for high balls because of the number of injuries from high balls.
I'd support that being introduced, every time I see a play jump into the air for a high ball, I cringe wondering who will get hurt.
I think jumping to catch a high ball, originally was done because it gives the catcher an advantage as they 'can't be tackled', but it still goes wrong so frequently.
