Sydney have banked a fourth straight AFL win, overcoming stern resistance from cellar dwellers Carlton to prevail by 30 points in a scrappy clash at the SCG.
The Blues gave travelling fans hope of a boilover by booting the opening two goals on Friday night then kept the Swans under pressure to boast an unexpected one-point lead at halftime.
The Swans busted the game open by kicking five goals to zip in the third term, eventually triumphing 13.13 (91) to 9.7 (61).
Lance Franklin managed three goals, having been one of many Sydney stars who struggled to find space, while both sides were guilty of butchering the ball and frustrating their own forwards with poor service and needless turnovers.
"Our intensity was up and down a little bit during the game, you really noticed when we were really having a go then we'd just relax a bit with that," Swans coach John Longmire said.
Isaac Heeney edged Callum Sinclair to collect the Goodes-O'Loughlin medal, awarded to the Swans' best player in the Marn Grook fixture that launched the league's Indigenous round.
"It's such an honour to win this and to have these two (Adam Goodes and Michael O'Loughlin) present it to me is even more special," Heeney said.
Franklin obliterated Carlton during the sides' previous clash, booting 10 goals in the final round of last year to claim the fourth Coleman medal of his stellar career.
Expectations built this week of another bag from arguably the game's greatest Indigenous player ever, who was depicted in a mural on nearby Flinders St to celebrate Indigenous round.
Blues backmen Sam Rowe and Liam Jones, who was crunched by friendly fire during a third-quarter collision with Jacob Weitering, this time combined to keep Franklin relatively quiet.
Franklin's frustration showed in the first quarter when he walked over the boundary line then threw the ball at the face of Rowe; the power forward argued his case but the misdeed remained one of three freekicks he gave away on the night.
Sydney defender Dane Rampe also voiced his displeasure with a decision that went against him in the first quarter, referencing Hawthorn coach Alastair Clarkson's catch-up with AFL chief executive Gillon McLachlan that followed Sydney's win over the Hawks.
"That is a ridiculous call. Clarko would be happy with that. Did you have a coffee with him too?" Rampe quipped to the umpire.
Ground staff errantly played the Swans' song shortly after Rampe's rebuke, reflecting the ease at which most pundits expected the home side to win.
The work ethic of the Curnow brothers, Sam Kerridge, Jack Silvagni and Jones kept the visitors in the contest before the wheels came off during the third term.
"We were right in the game. Some set shots really hurt us that quarter," Blues coach Brendon Bolton said.
"We just didn't use the ball well enough."
The low point came when Carlton veteran Dale Thomas bizarrely handballed the Sherrin to Kieren Jack, with the Swans rushing the ball down the other end for Franklin to kick his second goal.
