FORMER West Coast ruckman Callum Sinclair has changed clubs, cities and countless other things since losing the AFL Grand Final in 2015.

The unique sense of disappointment is something that hasn't dulled throughout the ensuing two years.

Most Sydney players harbour some form of Grand Final pain, with the exception of youngsters like Lewis Melican who are preparing for their first taste of September football.

Sinclair didn't contest the 2014 or 2016 season deciders, when the Swans started favourites but were rolled by Hawthorn and Western Bulldogs respectively.

But the big man, who is at the centre of an intense selection showdown at the SCG ahead of Saturday's elimination final against Essendon, was also a victim of the Hawks' charge towards three straight flags.

"You don't forget things like that," Sinclair said of the Eagles' 46-point loss in front of almost 100,000 spectators at the MCG in 2015.

"Very, very frustrating.

"Playing those home finals was unbelievable ... it was surreal, we felt like we were at the peak of our powers.

"It came crashing down pretty quickly, but obviously I took a lot out of the experience."

Just over a week after that match, Sinclair agreed to join Sydney in the trade period.

The 27-year-old looks back on his time with West Coast fondly, especially the chance to learn from Dean Cox and Nic Naitanui.

However, Sydney felt like home from the moment coach John Longmire showed him around the SCG.

"It was a bit of a whirlwind of emotion after that 2015 Grand Final," Sinclair said.

"I met John, Tom (Harley) and a few of the players, and knew I wanted to play here.

"The culture was very impressive from day one. I've loved every minute and am really grateful I made that decision."

Sinclair is hoping to follow the path beaten by ruckmen Shane Mumford, Darren Jolly and Jason Ball, who all became premiership players after being traded to Sydney.

Ruck coach Steven Taubert's work with the trio, as well as Canadian convert Mike Pyke, is renowned at the club but barely noted outside.

Taubert has also had a lasting effect on Sinclair.

"I've generated a pretty close relationship with him, I probably see him more as a mate now as well as a coach," Sinclair said.

"He's been terrific. Very honest. He'd do anything for you and vice-versa."
