Richmond defender Nathan Broad prepares to face the tribunal after attacking Adelaide’s Patrick Parnell

AFL coaches Chris Scott and Ross Lyon believe sling tackles will eventually be eradicated, with the process potentially being accelerated by Nathan Broad’s tribunal case.

Broad will face the tribunal on Tuesday charged with gross conduct over the tackle that left Adelaide’s Patrick Parnell with a concussion.

The Richmond defenseman faces at least a three-game suspension at a time if the AFL comes under closer scrutiny for their concussion handling.

“We used to train ‘tackle and dump’,” St Kilda manager Lyon told Fox Footy.

“Now it’s time to tackle and you have responsibility and duty of care.

“That (broad tackle) goes without saying why it shouldn’t be in the game.”

Scott, Geelong Premiership coach, said tackles like Broad’s used to be the goal of players when wrapping up an opponent.

“Not only was that okay, it was applauded,” he said.

“It’s like the bump now… the shift will be if you knock a player down you’re liable, so don’t do it.

“You’re better off tripping him with your weight.”

Lyon and Scott both have sympathy for some players suspended for rough behavior for wrong tackles when placed on opponents who are off balance.

Port Adelaide defender Ryan Burton has been suspended for two games after dropping Collingwood’s Jamie Elliott in one of those last-round scenarios.

Coaches don’t believe that modern players intentionally try to hurt opponents in sling tackles.

“It’s an aggressive, physical game. It’s instinctive,” Lyon said.

“These are split-second decisions and we are not machines and the players are under extreme pressure.

“I don’t think there’s any intent to hurt the player. Those days are over.”

Former North Melbourne champion David King described Broad’s duel as a “terrible incident” and “a car crash”.

King said he would be disappointed if Broad didn’t get at least a five-game suspension and called for an even bigger penalty.

“We have a chance to stamp that out and unfortunately Nathan Broad and the Richmond Footy Club have to pay a price for it,” King told Fox Footy.

“That’s a six-week weekend for me.”

King predicted that a ban of that length would deter other players from committing similar infractions.

“If you give that six weeks, it won’t happen again for the year,” he said.

“The grading was careless, high and strict – that’s the maximum – so don’t tiptoe through these.”
