Gold Coast coach Neil Henry led the Cowboys from 2009 to 2013 and played a significant role in forming the squad which delivered the club's maiden premiership in 2015.
He says there's plenty of reasons why the Cowboys can go where no other club has been in almost three decades.
"With Michael Morgan back in they are a settled side. They've been able to keep the same team on the park for long periods of time," Henry told AAP.
"It was a complete performance I just thought (against the Bulldogs). A 36-0 shutout.
"It's a little bit ominous ... it just shows what they can do."
For his part Henry is proud of his legacy at the Cowboys, who he led to 59 wins in 128 matches during his five seasons in charge.
He says a key plank of the success the club is no enjoying is the development of so many homegrown players.
"It's always been a good squad. It's been settled for a number of years now and the young players, the local guys, have got good experience of playing first grade," he said.
"Greenie's had some smart recruitment around that as well to get a few players in.
"They're playing a style of footy where they're confident they can play a full 80 minutes and they can come back and win games. They're a hard team to beat."
