The 2020 finals series has been a tryfest, with 34-22 the average score across the six play-offs so far.

That's in stark contrast to last year when it was 26-9 for the finals campaign.

Getting their defence right will be especially important for the Green Machine, who take on the typically miserly Melbourne Storm at Suncorp Stadium in the preliminary final on Friday.

Stuart said while some of his players were carrying niggles - like prop Josh Papalii (ankle) and Jordan Rapana (sternum) - he expected them all to be right for the Storm.

The high scores in this year's play-offs had some pundits thinking attack had become more important than defence in the wake of the changes brought about by the coronavirus pandemic.

ARLC chairman Peter V'landys's six-again rule has led to faster, more-continuous play - and higher scores.

But Stuart's focused on getting his defensive line in place when he goes up against his good mate - Storm coach Craig Bellamy - rather than looking to get involved in any sort of shootout.

"The scores are only there because there's been defensive deficiencies," he said.

"I'm still very focused on our 'D'. I thought we did a good job against both teams we've just played.

"Both are very good attacking teams and both teams we've done a good job on in regards to our defensive targets.

"But I still believe we can be better. We're striving for perfection in defence - and all parts of our game - and hopefully on the way to perfection we're improving."

Raiders fullback Charnze Nicoll-Klokstad was excellent in their semi-final win over the Sydney Roosters.

He ran for 253 metres, made a linebreak and three tackle busts, and saved a try as well.

Stuart said that was the standard all 17 of his players needed to produce against the Storm.

"Charnze's performance on the weekend is what I'm expecting from every individual," Stuart said.

"They need to play to their maximum performance to be in the frame to win and anything below that just puts too much of a threat towards the team.

"It's everybody's responsibility to perform at the highest level. That's what it takes to win finals footy."

Stuart was confident the 17 who were too strong for the Roosters would be available to face the Storm.

Papalii hurt his ankle scoring the opening try, while Rapana copped an accidental knee to his sternum.

Raiders co-captain Jarrod Croker copped a knock on his shoulder, while halfback George Williams crashed into the uprights scoring his try.

But they all finished the game and were expected to play in the prelim.

"No one's reported something that should restrict them from playing," Stuart said.

Storm five-eighth Cameron Munster was under a cloud with a knee problem, but Stuart's response was a simple one when asked how he prepared for the Queensland No.6.

Munster has struggled with his knee this season, having missed four games due to two separate medial ligament sprains.

"He'll play," Stuart said.
