So League has banned the shoulder charge at NRL level. Apparently it has been outlawed in New Zealand league since the mid 1990s, although only at schoolkids' level. Given the state of New Zealand Rugby League communications in recent years, I'd missed that development.
So far, the NRL has just dipped its toe in the water with an announcement about what will "likely" happen, presumably to measure the moral outrage.
Almost to a man, the sport's top players ridiculed the decision but the administrators appear adamant. It will be to their - and the game's - detriment. The major beneficiary of such a move is likely to be rugby union which has legislated against "no arm" tackles for a number of years now. Ironically, just as returning superstar Sonny Bill Williams goes back to the 13-man game, the NRL is moving to ban his trademark defensive weapon.
The administrators' move is a knee-jerk reaction to a problem which is covered by the rules anyway. Rugby league has long had a rule which outlaws attacking the head in any form and it appears to be used regularly and consistently by referees.
The irony is that the blazer wearers have done nothing about the reverse situation where the ball-carrier uses his head to target would-be tacklers.
