St Kilda coach Ross Lyon believes AFL football operations manager Adrian Anderson set a 'dangerous precedent' with his comments relating to the umpiring in last Saturday's clash between the Saints and Collingwood at the MCG.

Anderson said the performance by the umpires in Saturday's game, which saw a 23-12 free-kick count in St Kilda's favour, was 'below average'.

Lyon said he was concerned by Anderson's comments on Tuesday suggesting the 'rub of the green went against Collingwood in terms of the mistakes that were made'.

"When you talk about rub of the green throughout the year I think we've had some games that the rub of the green hasn't gone our way but we don't sit there and ask people to analyse," Lyon said on Wednesday afternoon.

"But even within that game I thought we had some decisions that didn't go our way. Did we have more or less than Collingwood? I don't know because I've moved on. I think it's a dangerous precedent."

"I think there was lot of noise made post game. But obviously it's a hot topic at the moment so it's easy for everyone to buy in."

"Obviously for Adrian Anderson to speak he thought it was appropriate. It's not for me to judge his intentions."

"If you want to analyse one game you want to analyse every decision and every game."

Lyon was guarded when asked to comment on the charges his spearhead Fraser Gehrig faced as a result of a nightclub brawl last year on Grand Final eve in Melbourne.

The issue was brought to the fore on Tuesday after video footage of the brawl was made public.

"We support our players. And clearly it's in the hands of the police so we'll let it run that course," Lyon said.

"It was released, why it was released, what were the intentions and the agenda I don't know, that's not for me to answer."

"It's obviously evidence and I thought it would have went through the courts but clearly it's been released for some reason which I'm not aware of."

"I think it's dangerous ground for me to start having judgments and opinions on. We're all ruled by the law of the land and we have faith in our legal system that the correct judgments be made."

Lyon was tight-lipped when asked to respond do Anderson's suggestion that players should also face club-imposed sanctions if found guilty by the courts.

"I think it's something we'll assess if and when that happens," he said.
