Hawthorn superstar Lance Franklin believes a repeat of the Hawks' AFL preliminary final inaccuracy could cost them a premiership.
Franklin acknowledges he was a major culprit on Saturday night as Hawthorn entered their attack 26 more times than Adelaide and had 10 more scoring shots, yet scraped home by just five points.
"We missed a lot of set shots, a lot of snaps," Franklin told reporters on Sunday.
"This week we need to take our opportunities when we can, because otherwise it can cost us."
Franklin's radar was wonky from set shots.
He kicked 3.5 and sprayed another shot out on the full.
"I think I had (former Hawks president) Jeff Kennett's boots on, the way I was kicking," Franklin said.
"I obviously just didn't kick as straight as I would have liked ... I was disappointed in myself but we were able to win so that was good."
Franklin's goal-kicking remedy: "Just keep practising and hopefully it comes off."
The Hawks expect to regain skipper Luke Hodge, a late withdrawal for the preliminary final with gastroenteritis.
Hodge's teammates have not seen him since training on Friday, with the captain skipping Sunday's recovery session
But they have no doubt he'll be back.
"I don't think anyone would want to miss a grand final so Hodgey will get himself right," Franklin said.
Defender Brent Guerra, battling to return from a hamstring injury, is more of a long shot.
"He's been really training hard the last couple of weeks to get himself up for this game, so it's a hard decision," Franklin said.
Sydney's Ben McGlynn is similarly placed, also fighting the odds to overcome a hamstring injury.
All-Australian defender Ted Richards is expected to play despite rolling his ankle on Friday night.
A greater worry for Sydney is a match review panel investigation into Swans ruckman Shane Mumford, who might be charged on Monday with targeting the injured right knee of Collingwood forward Chris Dawes.
Video footage is inconclusive, but shows the pair jostling then Dawes going immediately to the nearest umpire.
One positive for the Swans is that they have had almost a full day's extra recovery time, after a more comfortable preliminary final win.
But Hawthorn's most finals-experienced player, former Port Adelaide premiership star Shaun Burgoyne, doubts that will matter.
"It's a 50-50 game," he said.
"We'll recover well this week, we'll do everything right to get ourselves up, to give ourselves the best opportunity to win this game and they're going to do the same."
