A fortnight into the French series and never has there been more pressure on World Rugby to differentiate between the increasing incidents of accidental foul play which cause injury, and the flat-out dirty stuff of which there is less and less these days.
A day after the dramatic events at Westpac Stadium, Steve Hansen's sympathy was still with the French after Benjamin Fall's red card following his mid-air collision with Beauden Barrett, plus the match officials and especially referee Angus Gardner who was simply ruling to the letter of the law.
But he stressed the need for common sense has never been greater in a game which is become more dynamic and high-impact by the week. Few people want to see red cards for incidents like Fall's because it was clearly an accident and the test was effectively over as a result.
Various alternatives to red cards for such acts have been suggested in the wake of Fall's early departure from the pitch - including an "orange" card of 20 minutes in the bin, a yellow card with the offending player replaced rather returning to the field, and a report system, which is effectively already in place in the form of a citing commissioner.
"Our game is a collision game so there are going to be accidents in it," Hansen said a day after the 26-13 win in Wellington. "At the moment we're trying to treat every collision the same. Deliberate foul play – there's no room for it and it should be dealt to with a red card.
