There's a hint of suspicion that self-preservation may have crept to the top of leading referees' agendas in recent weeks and it is damaging the All Blacks' ability to play their natural game.
In what was a pulsating and classic test at Twickenham, the All Blacks came away feeling they didn't get a fair deal at the breakdown. As winners, they can raise the point not as an excuse but with a genuine desire to get it fixed.
It was their view that the England players mostly went off their feet, sealed the ball off and got away with it.
As a consequence, the All Blacks chose to be highly selective about competing for the ball. Because of that, referee Craig Joubert said England's approach made no material difference as they were going to secure possession anyway. Classic chicken and egg and yet when the All Blacks decided they should do the same and seal the ball, they were penalised - because England made the decision to compete every time.
There is no dispute that Joubert's approach made for a flowing contest - but it was, nevertheless, inconsistent and baffling for the All Blacks, who now wonder whether referees are trying to fulfil an edict.
