That's the belief Raiders gun Jack Wighton has ahead of their grand final rematch against the Sydney Roosters at the SCG on Friday.

Wighton will be a key figure in the Green Machine progressing to a preliminary showdown with the Melbourne Storm in Queensland.

He's in devastating form, scoring eight tries in his past six games - including a brace in the elimination final win over the Cronulla Sharks at Canberra Stadium on Saturday.

The 27-year-old has made ensuring there's no hint of second-year syndrome a focus this year, having switched to the halves in 2019.

It's safe to say he's done that emphatically.

He took out the Clive Churchill Medal in last year's controversial NRL grand final loss to the Roosters and is in even better nick this season.

But he's not the only weapon the Raiders boast.

Their forward pack, led by Josh Papalii and Joe Tapine, has plenty of strike, while Wighton's halves partner George Williams has established himself as an NRL halfback.

There's also threats in the outside backs, with winger Nick Cotric co-leading try scorer with Wighton on 12.

It's those threats across the park that has Wighton confident going up against the Roosters.

The Raiders beat the Roosters 24-20 at the SCG three months ago, although that's the only time they've beaten the reigning premiers in their past five encounters.

"We've got a good bunch of boys. We've got good middles. We've got strike power everywhere too," Wighton said.

"[If] we turn up on the night and we can put it to any team in the NRL. I truly believe that.

"But as I said it's about turning up. It's that game-on-game, week-on-week type of thing."

To do that though, Wighton said they'd need to start better.

While they've dominated second halves this season, they've struggled in the opening stanza at times and have only scored the opening try twice in the past 10 games.

They found themselves 14-10 down against the Sharks before blowing them away in the second 40.

But Wighton didn't think they would have the same luxury against a Roosters led by "world-class" five-eighth Luke Keary.

"We can't start the way we did [Saturday night or] we're going to be buggered," he said.

"So it's going to be a massive goal and they're a crafty team, a very good team."

Wighton was happy his quick thinking paid off against the Sharks, with his first try coming off a quick tap as the Cronulla defence was caught napping.

He was also pleased his work with Williams on the training paddock paid off for his second - when he flew to grab the England international's kick.

Wighton said it was the pair's job to turn games around when the Raiders needed them to.

But it's the hard work he's put into his own game that he's now reaping the rewards of that pleased him the most in just his second season wearing the No.6 jersey.

"There's a lot of [talk about] first-year luck. My point was to come out and stand up for the boys and take away that first-year luck," Wighton said.

"I work hard for everything I do. To get a little bit of luck and consistency the way I am I'm very proud of that."
