NSW's personnel, game plan and attitude have changed since Mitchell Pearce most recently played Origin, but the recalled halfback has quickly bedded in.
Mitchell Pearce's sudden State of Origin return has proved seamless, at least on the training paddock.
Pearce was called into NSW's camp on Wednesday after incumbent halfback Nathan Cleary was ruled out of the Origin decider.
The veteran, often the Blues' whipping boy while featuring in seven losing series, rushed from Newcastle to Sydney after getting the call from coach Brad Fittler.
Pearce hasn't had much time to wrap his head around an unexpected shot at Origin redemption, nor work on his rapport with a stack of new teammates who have come into the side since his previous NSW outing in 2017.
But James Tedesco suggested there were more than enough familiar faces, notably halves partner James Maloney, for Pearce to click instantly.
"He's got a few Newcastle teammates here and guys who have played with him before at the Roosters," Tedesco said.
"That's definitely a plus, knowing how Pearcey plays is going to help.
"I've played a bit with him in Origin before. He and Jimmy have got that combination from their time at the Roosters, it doesn't take too long to get back going.
"We all know how well he's been playing at club level, he's going to bring that confidence to this arena and that will be really good for us."
Tedesco suggested the Blues wouldn't tweak their game plan because of Pearce's inclusion.
"It's just him learning our structures ... knowing our players, getting the combinations going so everyone is on the same page," the fullback said.
"It doesn't take too long. It's all feeling good, we've had a couple of solid sessions."
Newcastle forward David Klemmer, who like Pearce earned a late Origin call-up for game three, was full of praise for his NRL captain.
"It's a big thing for him to be here. I'm happy and proud of him that he's got an opportunity, especially in a big game," Klemmer said.
"He's worked really hard. People don't see that every day, I'm very lucky I do.
"Outside football he's worked really hard on being a good leader, a good captain and a good person."
