Dean Cox has forecast only "little tweaks" to John Longmire's coaching systems as he prepares to lead the Sydney Swans into a new era from 2025.
Longmire officially stood down as the Swans' senior coach on Tuesday after 14 seasons, 333 games, five AFL Grand Final appearances and one premiership victory.
The Swans had routinely denied a succession plan had been in place to replace Longmire with his long-time assistant Cox, who was only offered a four-year deal last Tuesday.
But Cox had always been privy to Longmire's plans to resign at the end of either the 2024 or 2025 season -- aspirations held by Longmire for 18 months but only revealed publicly at Tuesday's press conference.
"We've sort of stayed in constant dialogue all the way through. The possibility arose and I'm really excited about it," Cox said.
An assistant to Longmire since 2017, Cox had long been tipped as a senior coach in waiting and most recently repelled advances from former club West Coast this season.
The 2006 premiership player was the Eagles' ruck coach for three years after his retirement in 2014.
Cox said he would not have quit that job and relocated his young family to Sydney had he not felt the move would one day lead to a senior coaching opportunity.
"John's known for a period of time, probably as the footy club has, that I always wanted to be a senior coach, hence the move over from WA," Cox said.
"It was a big one for our family at the time but it was one that you had to do."
The Swans' transition to Cox comes 14 years after Longmire replaced outgoing premiership coach Paul Roos following his own apprenticeship as an assistant.
Chairman Andrew Pridham joked at Tuesday's press conference he would see Cox "in 14 years" -- eluding to another regeneration from within the club.
The Swans have remained almost perennially successful since Roos took charge in 2002, making finals in 19 of 23 seasons.

Cox paid homage to that stability in eluding to his plans for next season.
"One thing that I'm extremely proud of this organisation, is the sustainability of performing to the highest level," he said.
"Our players produced some amazing football this year and that's something that we're extremely proud of. There'll be some little tweaks that I do differently from John but overall, it's a well-run footy program.
"It has been for a long time and we'll make sure that we give the players the best chance that they can continually perform."
Cox's top priority as a coach is to help players forge the kind of career he himself enjoyed.
The six-time All-Australian played 290 games for West Coast, including the 2006 premiership triumph over the Swans.
"My playing career ended and when it finished I was all about, how can I try and help players experience what I experienced?" Cox said.
"For me, it's about trying to make sure that they have an experience that they play some really good footy, they enjoy doing it together and then when they leave, hopefully their life is set up that they can go onto the next phase."
