SYDNEY Swans coach John Longmire says he'll give himself five minutes to sit back and reflect on the second minor premiership he's won with the club. 

The Swans 113-point demolition of Richmond at the SCG on Saturday night sealed top spot on the ladder for Longmire's men with their 17th win of the year, and secured the side a double chance and two home finals.

Despite the outstanding display in which the Swans at one stage booted 16 unanswered goals against the Tigers, Longmire, who also guided the Swans to the minor premiership in 2014, wasn't about to break out the champagne.

"It's important to play well for the year - it is a marathon - but the reality is that season is now finished and the new season is about to begin," he said post-match.

"Hopefully we've got some confidence in the type of football we like to play, but whenever the new season starts we need to be as sharp as possible and playing our best football.

"That’s our challenge now regardless of what's happened, we need to play really strong football for a month and that’s what we'll try and do."

Five talking points: Sydney Swans v Richmond

Longmire said the Swans would treat next week's bye the same as they would during the regular season, with their finals opponent, date, and venue still unknown.

Young defender Callum Mills missed the Tigers clash with a calf issue, but the coach said the NAB Rising Star favourite is in no doubt for the finals opener.

"I'd say he'll definitely be right for the next game, we were a bit conservative with him," Longmire said.

"He wasn't able to train on Thursday and we didn't want to push it too hard, but he was walking around today saying he could have played, so that’s a good sign.

"I'd say he'd be an absolute certainty."

Star forward Lance Franklin launched a late bid for his fourth Coleman medal with a seven-goal haul against Richmond, but given he started the final round 13 majors behind West Coast's Josh Kennedy, he was never a serious chance.

Franklin missed last year's finals series when he took a break from the game to treat some personal issues, and Longmire said the 74-goal season was great reward for the West Australian's hard work.

"He's been good the entire year," he said.

"I thought his pressure was outstanding tonight. It wasn't just about the goals, he was working really hard up and down the ground.

"He's been terrific and I'm sure he's really looking forward to it (the finals)."
