Warriors coach Andrew McFadden believes some shoulder charges should be allowed in the NRL.

McFadden says dangerous tackles should be outlawed, but some challenges were “just really good contact”.

“I think the old shoulder charge should be banned, that’s for sure, where you tuck the arm by your side,” he said.

“But front-on contact shoulder charges, I’m not sure.”

Sydney Roosters prop Kane Evans’ big hit on Canterbury front-rower and former Kiwi Sam Kasiano last weekend has led to arguments for and against the shoulder charge being allowed back into the game.

Evans was placed on report, but ended up not being charged.

McFadden said the fact Evans escaped a charge showed there was still debate over what constituted a shoulder charge.

“Sometimes, it’s just really good contact and I think those sorts of tackles should be allowed in the game,” he said.

“That’s the fabric of our game. That’s what makes people turn up every week.

“We want to see that and we want safety as well, so there are types of tackles we need to outlaw.”

Meanwhile, McFadden said the Warriors intended to continue with their new policy of having players in all three competitions – NRL, NSW Cup and under-20 NYC – shake hands with the referees after matches.

The issue of referee abuse has been highlighted by Cronulla prop Andrew Fifita and brother David being stood down by the Sharks over an alleged incident at a junior match.

McFadden said he and club chief executive Jim Doyle had been speaking over the past two or three months about introducing a handshake policy.

“What happened last week with the Fifita boys jogged our memory and we thought it would be a good idea to start something, because it’s a difficult job the referees do,” he said.

“They’re in a lose-lose situation sometimes. We thought it would be a good idea to show them respect so that’s what we are going to continue to do.”
