Cameron Munster has thrown his support behind embattled Queensland halves partner Ben Hunt, arguing the Maroons were the better side in their State of Origin II loss.

Hunt has been singled out for criticism after a string of poor decisions in NSW’s series-clinching win in Sydney last weekend.

Coach Kevin Walters has already said he is unlikely to make any changes to his scrumbase pairing on Sunday when he names his side for the game three dead rubber.

However he may be forced to shuffle his forward pack after Dylan Napa suffered a knee injury in the Sydney Roosters’ loss to Melbourne in Adelaide on Friday night.

Hunt responded to his critics in the best possible fashion on Thursday night when he produced a perfectly-weighted grubber for Euan Aitken as St George Illawarra surged late to run over the top of Parramatta.

Just four days earlier Hunt booted the ball dead from a similar position during Origin II, blowing a golden scoring opportunity.

However Munster said Hunt was still the right man for the job.

“Ben’s the best performing halfback in the comp,” Munster said.

“Whoever Kevvie decides to (select), we’ll see how we go.

“But I feel like Ben Hunt’s our best seven.”

Munster argued the Maroons deserved to win game two after being in control for most of the proceedings, however gave credit to the Blues for owning the big moments.

“We’ve always got belief,” Munster said.

“I know the scoreline doesn’t reflect how good we were. I thought we were the better side in the second game to be honest.

“In some key moments the Blues were better than us, it’s something we need to be better at in game three, have a good game and avoid a cleansweep.”

Napa is once again racing the clock to be fit for Origin III after suffering a suspected medial ligament injury in the Roosters’ loss to Melbourne.

Napa came from the field with a left knee injury with 10 minutes to play in Friday’s 9-8 defeat at the Adelaide Oval.

The Roosters prop had to overcome an ankle injury and prove his fitness to Queensland officials before taking part in last Sunday’s game two loss at ANZ Stadium.

Early indications were that Napa had suffered a medial ligament injury, which would put him in extreme doubt.

Should Napa fall short, it would open the door for Brisbane’s Joe Ofahengaue to make his Origin debut.

It would also provide a reprieve for Jarrod Wallace who is under pressure to hold his place after failing to run for more than 44 metres in the first two Origin matches.
