"It's not about any other teams," Lyon said.
"Each week we've got a new game and a new challenge. It's about the immediate opposition. We know what we've got to do to play good league football. It really starts from our preparation and our review.
"What anyone says, whether it be print media, TV, opposition coaches, I go home and my dad has a comment. It doesn't matter. We know how we've got to prepare and unless you reproduce those actions consistently you get embarrassed really quickly in league footy."
Lyon said injured pair Sam Gilbert and Stephen Milne were likely to play this week, while Michael Gardiner was disappointed to be suspended.
But far from scolding his in-form ruckman, Lyon said Gardiner's suspension was a consequence of the ruthless style of football St Kilda has employed this year.
"The guy came in to shepherd him and he made a poor decision how to protect himself. It probably looked worse than what it was," he said.
"We're playing pretty hard football and we'll cross that line a few times. We'll just have to deal with it."
The Saints will be searching for their 11th consecutive win this week, which would eclipse the record of 10 set at the start of 2004, but Lyon said the record was irrelevant.
"What's the lesson for 11 in a row? It counts for nothing. That's the lesson if you want to look back and look at '04. This is a different group, five years on. Mick Malthouse has said it's a marathon and we know that," he said.
"At this stage we still haven't won enough games to guarantee a finals appearance. Clearly our aim is to continue to improve and win. It's not about how many games in a row. We can win and go backwards or we can lose and think we've gone forwards. That's where we're at."
