ADELAIDE believes an inside edge, rather than need for speed, is the key to halting Greater Western Sydney's record winning streak.

While most marvel at the Giants' flashy speed, the Crows have studied their knack of winning contested ball ahead of Saturday night's encounter at Adelaide Oval.

"Rather than speed, it's going to be the ability to win the ball at the contest and try and limit their ability to spread and run off us," Adelaide assistant coach David Teague told reporters on Friday.

"Their speed is enormous when they have got the ball. If we have got the ball, it's going to be our ability to move the ball quickly against them.

"We feel if we can win the ball and move the ball forward, we can test them out too. We have got some handy players forward of the ball that they have got to defend."

The Crows are highest-scoring team in the league and the Giants, on a club-best six-game winning streak, are second-highest.

GWS lost Tim Mohr (hamstring) and Matt Buntine (concussion), recalling Adam Tomlinson and Jack Steele for the night match.

Eighth-placed Adelaide named an unchanged side with Luke Brown passing a fitness test on an injured ankle.

Brown's defensive speed is vital for the Crows, who Teague said were improving at covering the slick spread of opponents after being caught out in a loss to Geelong a fortnight ago.

"It is something we have focused on and we were a lot better last week," he said.

"The challenge this week is a different opposition … but we need to make sure we can match them on the inside and then when the ball leaves, that we spread.

"We will go into the game playing our style. We believe that our best is good enough to beat GWS ... we have got a strong belief that we can get the job done playing our way, our style and our brand." 

Meanwhile re-signed midfielder Rory Atkins says he isn't about to pressure his teammate Josh Jenkins to ink a new deal with the Crows.

Atkins, an emerging 17-game player, has signed a two-year extension with Adelaide, who are sweating on a deal for the sought-after Jenkins.

The Brisbane Lions this week denied offering a bumper bid to Jenkins, who is off-contract at season's end.

But Atkins says when it came to contracts, everyone was different.

"There's a lot of things that need to be assessed," Atkins, 21, said on Friday.

"But I'm confident that we have a very close group, a very young group, and we're striving for success and going the right way in doing that."

Asked if Adelaide players had made a pact to stick together, Victorian-born Atkins replied: "There's definitely not anything structured, stuff like that usually just happens catching up with a mate or a group of guys for a coffee," he said.

"There's more of a bias to stay with the group that you feel comfortable with."
