PLANNING for next season remains at the forefront of Sydney coach John Longmire's mind heading into the remaining two games of a disappointing campaign.

The under-manned Swans have been brave in the past five weeks, but the dam wall finally broke in their 47-point loss to Port Adelaide at Adelaide Oval on Saturday.

It was the sixth straight defeat for the Swans, dropping them to 6-14 and remaining 15th on the ladder with games against Melbourne (MCG) and St Kilda (SCG) to round out their season.

"It's about setting our team for next year, and not waiting until next year or the pre-season to get going," Longmire said.

"We can do it at the back-end of the year.

POWER TOO GOOD FOR SWANS Full match details and stats

"We've been pretty good at that as far as doing some things that can help us next year."

The Swans had an identical number of scoring shots as the Power in the first half, but found themselves down by 15 points – 7.7 (49) to 4.10 (34) – thanks to some wayward finishing in front of goal.

"One of the things we didn't do well was keep pushing the second half as much as we have been," Longmire said.

"We've been down in games and come back hard.

"The young players have learnt from that, and they'll learn from today, that you need to win your contests in the second half and take your chances in the first half and don't present so many opportunities to them."

The Power turned on the jets after the main break, their ruck tandem of Peter Ladhams and Paddy Ryder feasting on a Swans' side without a specialist ruckman.

The Swans lost all 20 centre hit-outs while the Power won all but one centre bounce clearance after half-time.

"We lost too many contests and centre bounce clearances," Longmire said.

"We were constantly on the back foot with that.

"We've got to get that part of the game right."

One of the positives was George Hewett's tagging job on Power midfielder Travis Boak, restricting the prolific ball-winner to 13 disposals.

Youngster Oliver Florent found plenty of the ball with 29 disposals, while exciting forward Nick Blakey had 20 touches playing on a wing.

"I thought Ollie was good and we exposed him to a different role," Longmire said.

"For Nick, it was his first solid period of footy on the wing.

"We tried to mix that up a little bit."
