WEST Coast milestone man Josh Kennedy has plenty of football and goals left in him, but warns the days of forwards kicking big bags are becoming fewer and farther between in an era of congestion.

The Eagles spearhead believes that if any player can kick 100 majors in a season again, it will be Sydney superstar Lance Franklin.

Kennedy, who turns 30 next month, is due to play his 200^th AFL game – after 22 matches for Carlton - in Sunday’s crunch clash against Collingwood at Etihad Stadium.

He will share the milestone with fellow vice-captain Luke Shuey in his 150^th match and utility Elliot Yeo, who is set to notch his 100^th game coming back from knee soreness.

Despite a recent calf/Achilles issue, Kennedy is at the peak of his powers and told AFL.com.au his desire to at least see out the remaining two years of his contract – and win a premiership – is as strong as ever.

"I'd love to keep playing as long as I can, but most guys who finish up and retire … you probably maybe want to be able to punch out one more year, but you probably call it quits then,” Kennedy said.

"I'd hate to go one year too long where you're trying to get through and your body is too sore.

"Hopefully I can reach those ages of 33 or 34 – that would be nice – but if not, I've always said I want to play until I got to 30 and I'm 30 this year, so anything after this is a bonus, I think."

Kennedy feels physically and mentally fresh after tweaking his game preparation in recent years.

At least once a week he floats in salt water-filled pods at Beyond Rest Wembley – a business he has bought into – to relax his body and mind.

"There's a whole range of benefits,” he said. “You get a heap of magnesium absorption for your muscles.

"Having an hour off your joints, there's no pressure on your body.

“I do it the night before a game to feel a bit more refreshed the next day, a bit more clear in the head.

"The mental side of things is you can have an hour to yourself with no distractions at all.

"Feeling pretty fresh on game day is something that has helped heaps.”

The routine seems to be working, with Kennedy the AFL’s most prolific goalkicker in the past three years and the key to the Eagles’ finals hopes.

The spearhead’s return from injury in last Sunday’s Western Derby came at a critical time for eighth-placed West Coast, while Kennedy is also still in the hunt for a record-equalling third straight Coleman Medal.

But pinching the medal is not on his radar and kicking the bags required to overtake Franklin, who has scooted 10 goals ahead of him, will be tough in an era when team defence is king.

"It is getting harder (to kick bags),” said Kennedy, who needs 13 more majors to reach the 500-goal mark.

“In terms of your opponents, everyone is getting more skilful and there's a lot of great backmen out there these days.

"As a forward it's so hard these days to try and find some space.

"But then you've got guys with massive talent like Buddy and [Gold Coast’s Tom] Lynch, and some of these young kids coming through, you can see the potential there to kick big bags."

Kennedy, Franklin and Lynch are the only players to kick more than six goals in a game this season.

That trio – along with emerging Bombers superstar Joe Daniher and Giants gun Jeremy Cameron – stand out as the forwards capable of kicking a ton again.

But not since Franklin, who has had 21 more scoring shots than any player this year, achieved the feat in 2008 has anyone broken the 100-goal barrier.

"If anyone is going to do it, it's Bud with the amount of shots he has," Kennedy said. 

Kennedy’s best return was 82.37 last season after he booted 80.55 to lead West Coast to a Grand Final appearance against Hawthorn in 2015.

The frustration of underperforming on the big stage still burns the Eagles and Kennedy, who was held scoreless and restricted to nine touches by James Frawley.

Losing a home elimination final to eventual premiers the Western Bulldogs last year added to the pain.

But West Coast is still in the hunt this year and while Kennedy and Nic Naitanui, when he returns, are in their prime the Eagles will loom as a potential flag threat.

"[The 2015 Grand Final] is something you always reflect on and a disappointing day. It's so hard to get there,” Kennedy said.

"The hardest thing is that when you play week to week and you don't perform, you know you've always got that week of training and then the next week to get back on and get into some good form.

"With the 'Granny' you only get one chance to prove yourself.

"Hopefully before I finish we can get another crack at it."
