The number on his back puts him at juicy odds in try-scorers markets but the speed and footwork belying his sizeable frame has given the 27-year-old a knack for finding the try-line.

He's grabbed 26 tries throughout his career but it's been a bare cupboard in 2019, at least until Wednesday night's decider.

It's unlikely he'll ever score a more important try than the 34^th minute four-pointer that locked the scores at eight apiece at halftime.

Vaughan certainly can't think of one more memorable.

"It was such a surreal moment," Vaughan said.

"I haven't scored a try all year, I normally jag a couple but it's been a bit of a lean year. It was funny because me and Damien were practicing that play [on Tuesday] at training.

"He just said 'if the opportunity arises put yourself in that position and I'll put you over'. He'll take all the credit for it but it was unreal, it'll go down as one of the best Origins for a very long time.

"I'm just happy the boys got the win and going back to back is pretty special. Hopefully, if we keep the core group of players around, it's going to be a very successful couple of years for us."

It leaves Vaughan 2-0 in his Origin career having been part of last year's breakthrough series win, but he said the two campaigns have been chalk and cheese given the roller coaster 2019 turned out to be.

"You could probably write a book about it," Vaughan said.

"The first game a couple of things didn't go our way and they ran away with it, the second game we blew them off the park. [on Wednesday] they played great, we didn't play our best but we've got some freaks in our team and it was a great finish."

Vaughan and the rest of the Dragons Origin contingent will now turn their attention to rebooting their season in clubland with Sunday's clash with Canberra the first in a series of season-defining games.

"I thought the boys were really brave against the Storm last week," Vaughan said.

"It was a bit of a tough penalty in the dying stages of the game but the boys were really brave and I think we can take [Origin] form back into clubland.

"There's still a lot of rounds to go so we need to dig deep, win a couple of games and push on into the finals. Our season's not over yet and we've got quality players all over the park so we need to start putting wins on the board."

It'll be a personal mission for Vaughan who was a spectator in the Dragons run to last year's post-season after picking up a season-ending foot injury in round 21.

"It's definitely something that's driven me this year, missing out on the finals last year and not being a part of how well the boys went," he said.

"I always use that motivation to be a better player. It's great to experience [Origin victory], I just need to get a few things right physically. Hopefully I can do that and have a strong finish to the season."

He's admittedly carrying some niggles, but he's hopeful of backing up against the Raiders.

"I've been carrying an injury all year so it's been tough going," he said.

"I've been trying to manage it at best I can. I'd definitely like to [back up] but I'll just have to see how I go."
