Hooker Matt Ballin will be playing his third decider while only injury prevented David Williams and George Rose having more than one grand final appearance to their name.
Then there's the youthful halves combination of Foran and Daly Cherry-Evans, who have both spoken about the prospect of forming an alliance in the maroon and white for the next decade - provided they can resist the big money offers which will undoubtedly be thrown their way.
It's a temptation Sea Eagles management has so far largely been able to ward off - the likes of Will Hopoate, Tony Williams and a then-budding superstar Jared Waerea-Hargreaves the only departures Manly officials would rather have avoided.
"I can only put it down to the fact this is such a tight club," said Foran.
"It's the only club I've ever played at so I don't know any better, but blokes that come here from other clubs say they've never experienced anything like it.
"Blokes don't want to leave - the only way they leave is if they have to leave - otherwise blokes just want to stay here.
"We're all best of mates, we love playing with each other."
Off-season addition Justin Horo, who joined the Sea Eagles from Parramatta, noticed the tightness of the group almost immediately.
"It took me only a couple of weeks into the pre-season [to see it]," he said. "Training was really competitive, there was a lot of positive talk."
But while the core group has been the bedrock of Manly's success, coach Geoff Toovey said the impact of his recruits could not be underestimated.
Just as Joe Galuvao did with the 2011 premiership-winning team, the Sea Eagles have brought in a group of NRL cast-offs to solidify the side.
"You'll see most of the clubs that are successful have that core group of blokes," Toovey said.
"The big thing for us has been the blokes that have come in this year - [front-rower] Brenton Lawrence has probably been the buy of the year.
"We lost a few players last year but replaced them with, you could say, lesser known players - Brenton, Richie Fa'aoso even though he's [broken] his neck, Tommy Symonds came on board, Justin Horo.
"They've all made a fist of it and are loving it and are an important part of the team."
