SYDNEY Swans forward Ben McGlynn has refused to blame a contentious umpiring decision for the side's disappointing loss to Carlton on Friday night.

A free kick was paid for an interchange infringement in the third quarter that resulted in a Carlton goal, giving them a seven-point lead that they didn't relinquish for the rest of the night.

"I'm not too sure what happened with that incident. But you can't put it down to that because we let them have easy goals. That one was just part of the game so you can't really blame it on that one incident," McGlynn said after the game.

"There are a lot of things that changed in the second half. Our intensity at the footy wasn't there compared to the first half and that stood out with them winning the ground balls and contested balls in the second half. They had the momentum, we didn't have any to start with in the second half."

McGlynn was one of the Swans' best with four goals for the match but he said he took no joy from what was a poor night for his side.

"Team success is what we're after and a few goals don't matter when you lose. Once you're up forward the boys have got to make the most of their chances and we didn't do that tonight," he said.

"You want to win every home game and tonight we had a good opportunity to. Carlton is an up and coming team as well and have some good young players. We'll be competing with them up around the top eight so to let that slip is very disappointing."

McGlynn said the Swans adjusted for the wet conditions after constant rain hit Sydney over the past seven days.

But he conceded that maybe they didn't adapt when the ground dried up in the second half.

"You've just got to get it on the boot and get it forward. I just think that too many times we didn't put our head over the footy and they did and got it down the other end. It dried up in the second half so we could have changed the way we were playing. That's just the way it is," he said.

"I think Juddy (Chris Judd) had a fair influence in the second half. He dominated the middle and we couldn't stop his influence around the footy. There were a few weak efforts on our behalf as well.

"In the second quarter we didn't take our chances in front of goal. But the second half was not the standard we like to play at Sydney. It will definitely be looked at during the week."
