Sydney's in-form ruck duo of Shane Mumford and Mike Pyke can lead the club to premiership success according to co-captain Adam Goodes.

Goodes says Mumford and Pyke have played key roles in the team's charge to the 2012 decider, the Swans pair well matched against Hawthorn's duo of David Hale and Jarryd Roughead in support.

"The whole ruck thing with the sub rule has been a bit of a headache the last couple of years. What to deal with it. How to deal with it. Does LRT (Lewis Roberts-Thomson) become our second ruck?" Goodes said on Tuesday.

"I think what Mike Pyke's been able to do this year, he has come in and played a really crucial role.

"If you get a second ruckman who can come in and take a mark and kick a few goals here and there, it's just a huge bonus.

"That advantage West Coast have with Dean Cox and Nic Naitanui, having two really quality ruckman, can help against those teams that don't have two quality ruckmen."

"Obviously Hawthorn have got Roughead as the back-up ruckman, and if we can get a bit of dominance when that happens with Mike Pyke, that's a big plus for us."

Goodes insisted the Swans had learned their lessons from their round 22 loss to the Hawks at the SCG in which the visitors trailed by 38 points midway through the second quarter before claiming a thrilling win.

"Our biggest strength this year has really been our ability to play four quarters and grind teams and we need to play for four quarters on the weekend," Goodes said.

"The last time we played the Hawks, we didn't play for four quarters, we didn't finish off the last two minutes and it cost us.

"It is probably going to be one of those games like the West Coast/Sydney grand finals (a four point win to the Swans in 2005 and a one point win to the Eagles in 2006) I think and we're just really excited for that challenge."
