Dragged down by injuries in recent years and off-contract before a ball was kicked, Moylan was never under any illusion as to how important 2022 was for his career.
And it was clear from last summer that Hynes's arrival had come at a perfect time.
With them together in the halves, this is a Sharks side that is humming and on track to top 550 points in a regular season for the first time in two decades.
Hynes has attracted all of the attention at Cronulla this year.
From a utility at Melbourne to a genuine Dally M contender at the Sharks, he has been the NRL's form half of the season with his willingness to run the ball and take the line on.
But Moylan, too, is in the best form of his five-year stint in the Shire.
Not only back to full fitness, the 31-year-old is back providing the kind of silkiness he was renowned for at Penrith in his early years.
It has earned him a two-year extension, giving his career a second life and a shot at just his second finals series since joining the club in 2018.
And he credits that largely to not only the freedom given to him by first-year coach Craig Fitzgibbon, but his combination with Hynes.
"We both see the game pretty similarly," Moylan said.
"We worked really hard throughout the pre-season and felt like a combination started off pretty quickly.
"We both felt like we played alongside each other before. Obviously it's not a finished product and we've got a bit of work to do.
"(And now) I think it's the combination we have along with Brails (hooker Blayke Brailey) as well. We all see the game the same way and we want to play footy."
Hynes and Moylan had already moved in similar circles off the field, knowing each other relatively well before uniting at the Sharks.
But there are also real on-field similarities.
The pair both started their NRL careers as fullbacks, joining Melbourne duo Jahrome Hughes and Cameron Munster as the only other pairing in the NRL with a similar path.
"You get a different look from playing fullback as well," Moylan said.Â
"You see more than what a half does because you're a bit wider and playing off the back of them. That definitely plays into the attack side of things."
