It's also no deterrent
If we're assuming that a good percentage of these are accidental and essentially bad luck then no increase in punishment will be a deterrent
I know that some are bad technique, and others are accidents due to lack of care which could potentially be punished more harshly, but it still wouldn't stop it happening.
We already see players repeatedly infringing when an attack is on the 5m line.
If they don't infringe, the fear is the opposition get a try.
If they do infringe, invariably is a yellow card and often a penalty try.
Is that really worth the risk? On paper it's surely not... But that's the game.
All we'll see with harsher punishments and points being awarded is games that are even more one sided.
A team down to 14 men after 30 minutes can sometimes battle.
A team down to 14 men after 30 minutes and also an extra 14 points down has no chance
