"We need to be better than that,"the 2016 premiership coach said."Make sure we hold our nerve and don't change rules and adjust things on a whim. You need more than a one-event sample size to force change and we are too quick to flinch and it's not helping the game.
"We had a flinch last week and we don't need any more ... We do it too often,and it's not acceptable.
"Clarko has got every right as a statesman of the game to have his opinion and put that across but it's up to the powers at AFL to work out whether or not they flinch. And they flinched."
Clarkson said he'd been advocating for such a change since 2016,and that if the AFL really did act only on his whim it would have happened then.
"There'll be some in the game – and I am led to believe Hodgey[Luke Hodge] might have been one of them – that said'one person's influence shouldn't be enough to change rules',"the four-time premiership coach said.
