Willie Peters has defended his decision to make sweeping changes for the final round of the regular season, insisting that it gives Hull KR the best chance of progressing in the play-offs.

The Australian could field as many as eight debutants at St Helens after naming a much-changed squad for the trip across the M62.

Rovers, who have played more games than any of their Super League rivals this year, benefited from a recharge to book their play-off spot with a resounding win over Huddersfield Giants but Peters stressed this week's changes are more deliberate.

"We just felt it gives us the best chance for the finals," said the KR head coach.

"Finishing fifth or sixth doesn't make too much of a difference. We wanted to freshen things up because it's been a big season.

"With Wigan, as I said at the time, there were three players that we 100 per cent rested and possibly a fourth that could have played. The others were due to genuine injuries.

"It was a little different to this week where we're resting the whole squad. But you could see the benefit of guys having a week off. As a club, we've played 30-odd straight weeks and players have played big minutes.

"I certainly believe that giving the players a rest this week will give us a good opportunity to put in our best performance next week."

Peters accepts there are contrasting views on the balance between momentum and freshness but is convinced the benefits of a week's rest will outweigh any potential loss of rhythm.

"I know this squad extremely well and see them every day," he added. "There are going to be differences of opinion, which is fine.

"There are no excuses for fatigue or being tired next week because they're getting their rest this week. It'll be game on."

Peters has been encouraged by the half-back's attitude after missing seven of KR's last eight matches.

"Mikey has made the decision to play – a really mature decision," said Peters. "He's done his time and I always said that he would come back and be in our best team.

"He's going to captain the side and lead through his actions. He needs to get some game time but it was his decision to play this week and make sure he earns everyone's trust back in terms of what we know he can do."
