Co-captain Phil Davis believes Greater Western Sydney need to improve defensively next season.
The Giants secured a second straight top-four finish last year, but find themselves under pressure going into the new campaign.
They lost Nathan Wilson, who played 24 games last season, during the trade period when he went to Fremantle. And now Zac Williams, who racked up 23 games in 2017, is set to be out for the whole of this year.
I want to lead a backline that's more stringent than it's ever been before.Phil Davis
Coach Leon Cameron had a settled defensive unit last season, with seven players all registering career highs for games played in a campaign including Heath Shaw who managed 25 appearances.
They'll need to resolve their backline issues after Williams was ruled out long-term with a ruptured ACL.
The loss of him and Wilson means GWS won't have their two best attacking defenders, but Davis is confident the club will be able to find a successful mix.
"Our best is very good, but I think our form fluctuates a bit too much," he said. "I want to lead a backline that's more stringent than it's ever been before.
"I don't want lapses that cost us two or three goals in a row. I want to be part of a backline that is so consistent and reliable that we can be a board of solidarity for the whole team to look back on."
Davis has backed academy products Harry Perryman and Isaac Cumming to impress during the JLT Community Series. It will be a chance for Cumming, who has yet to make his AFL bow, to argue his case for incusion from round one.
GWS are 1212/1 to win the Grand Final.
The Giants are 1/250 to finish in the top eight.
