Between them, they have more than 500 games of NRL, State of Origin and Test experience, as well as premierships as player and coach.
Now Kiama's Brett Morris and Wollongong's Jason Ryles will combine to help Trent Robinson and the Roosters stop Penrith from building a dynasty.
Both Morris and Ryles were products of the Dragons system, but only played 16 games in the same team in 2008, before finding Bondi towards the end of their careers.
Morris was majestic in the Roosters 2019 title triumph, adding a second premiership ring to the one he won with St George Illawarra in 2010.
While Ryles was never so lucky on the field, he was on the other side of the field 11 years ago and injury robbed him the chance to win one with the Storm, Ryles became an integral part of Craig Bellamy's Melbourne machine.
With Dapto's favourite son Craig Fitzgibbons now taking charge at the Sharks, Ryles has the most impressive resume of any coaching apprentice, having most recently worked with Eddie Jones and the English rugby union team.
"Jason is a diverse thinker with a highly-impressive football nous which he has harnessed over the last two decades as an elite player and coach," Robinson said in announcing the double signings.
"Jason is also a strong relationship builder with huge integrity. I have no doubt that he will contribute significantly to our quest to be better every day and I am looking forward to working with him."
High praise indeed.
But yet, for all his experience, it's easy to forget that just six years ago, Ryles was back at Wests in the Illawarra competition, taking his first steps into the coaching caper.
And while Ryles has been well-travelled in his coaching career, for Morris, moving from the wing straight to the coach's box is a natural progression.
"Brett played more than 300 NRL and representative games and he has an astute mind with a genuine care for making the players around him better," Robinson said.
"I've been fortunate to be able to observe Brett's keen eye in video sessions and out on the field both at training and in games over the last three years."
Morris managed just seven games in his final NRL season before suffering an anterior cruciate ligament knee injury which forced him into retirement, before twin brother Josh bowed out in the 42-6 loss to Manly in the semi-finals.
