Leading into Sunday's win coach Ricky Stuart said Wighton remains a work in progress but he's certain he'll feel completely comfortable in the No.6 jersey by the end of the 2019 regular season.

But based on what he produced in the 26-22 win over the Broncos there's every suggestion he'll reach that point far sooner, with Wighton's combination with the green machine's spine improving again as they resigned Brisbane to their worst start to a season since the turn of the century.

Being the Raiders' fifth win from six starts, it's also their best opening to a season since 2003, and ended a six-game losing streak against the Brisbane side.

"That was a massive effort," Stuart said after the win.

"They're a lot more mature group this year. They're an easier team to coach this year because I feel that there's individuals growing up."

One of those individuals is Wighton, who struggled with a hip problem before the week prior's win over Parramatta, but had no issues on Sunday afternoon.

Wighton once again directed traffic with aplomb alongside halfback Sam Williams and produced one of the game's most crucial moments.

Brisbane hit the lead at the 59-minute mark but Wighton produced a crucial 40-20 which swung momentum back to the Raiders, who scored twice more as a result.

"I've noticed little things in Jack's game that are starting to improve and develop, and little things I want to keep trying to slowly introduce into Jack's game," Stuart said of Wighton.

"At the back end of the season he will find himself very, very comfortable into the role.

"A couple of those little kicks down the left edge there, you know there's a few things as a half you have to have a bit of courage to do them and we're trying to create that within Jack's game.

"There's certain skills we want to implement into his game ... because Jack's in a different position and has a different responsibility in the game than what he had at No.1."

Wighton's not the only part of the spine that's firing, with halfback Sam Williams keeping Aidan Sezer out of the team with his form, and hooker Josh Hodgson pulling the strings from dummy half.

They're finding the perfect balance between Hodgson and Williams' deft kicking games, as well as when Wighton gets the ball.

Wighton's running game has looked dangerous, especially on the left edge, while he's quickly adapted to using his booming left boot, as seen with the match-defining 40-20 on Sunday.
