Lyon was keen to point out that John Worsfold's theorising of a zone rule on Monday seemed to be just an idea, as opposed to any formal proposal from the AFL laws of the game committee.
Lyon said he would talk to a formal presentation on the concept but when asked about whether he would like to see a formal trial of zones in the pre-season he quickly let his feelings be known.
"Let's destroy everyone's pre-season," Lyon said.
Roos not keen on 'zoneball'
"We're an elite competition trying to get ready for an AFL season where we need to win, and all of a sudden … we'd be the only elite competition in the world that goes into a brutal competition not practicing the rules they're going to play in-season.
"I struggle with that concept, even though we're there to experiment.
"My take is, and I'm really firm on this, the uniqueness and magnificence of Australian Rules football always finds a way."
Lyon echoed the thoughts of his friend and mentor, Melbourne coach Paul Roos, in saying the game was as good as it has ever been.
"I think all the panic merchants need to have a cup of tea and a scone and just relax and let's see how we go," Lyon said.
"I think the game's in great shape. Tex (Walker) kicked five (goals last week). Buddy and Kurt Tippett are a dynamic duo up (in Sydney). They’re kicking 20 goals a week and there's a few teams kicking 16.
"I'm sure we'll have a great finals series again this year."
Player zones could help congestion: Worsfold
Lyon quickly turned his attention to Adelaide this Sunday with Taylor Walker at the forefront of his mind.
Walker has kicked 26 goals in seven outings against Fremantle and averaged just shy of seven marks per game. The Crows' key forward bagged a match-winning five goals to sink the Dockers in the 2012 semi-final when Luke McPharlin was absent injured.
McPharlin again has his injury concerns. He was clearly sore as he jogged laps at Fremantle's main training session on Wednesday morning.
The Dockers picked McPharlin as a late inclusion against the Western Bulldogs last Sunday after the veteran had not played since the Derby in round seven.
Lyon said managing the defender was one of his hardest tasks as a coach.
"Certainly he's a little bit sore so he'll just look after himself today," Lyon said.
"Etihad is a hard surface with the car park underneath and the concrete foundation makes it a bit harder.
"In 2012 he hurt himself in round 22. That was a period where we probably should have rested him.
"It is hard to do when you've got a fit available Luke McPharlin, leave him out. I find it challenging, personally."
Stephen Hill and Danyle Pearce also trained away from the main group on Wednesday but both moved freely jogging laps on the sidelines and should play Sunday.
Nat Fyfe did not train due to his swollen ankle. Lyon said he would need to pass a fitness test on Friday but was confident his star midfielder would play against the Crows.
"It's swollen. But he didn't suffer any severe damage," Lyon said of Fyfe's ankle.
"He should train Friday. And if he jumps all the hurdles, he should play. So we're really quite confident."
