The initial position was if there is foul play and head contact, there can be no mitigation.
Which is not at odds with not all head contact is foul play.
So a shoulder charge, or swinging arm, is clearly a penalty - and if there is head contact, then it is a card.
And at the start, it was an automatic red.
Now it seems that even when the commentators and viewers think stone-cold red, the bunker finds a butterfly clapped its wings.
I think it was possibly hard to expect players to change overnight in the highest pressure games.
But I think they have gone too far the other way.
I would like them to go back to the original position, after the world cup, and then keep it there.
