The Swans were forced to overcome injuries to Ben McGlynn and Jarred Moore in the second half, but they snatched their gutsiest win of the season with the last two goals of the game.
Hannebery, who starred in the midfield with 38 possessions, said a rousing three-quarter time speech from coach Paul Roos and captain Brett Kirk drew on the culture made famous in the grand final years of 2005-06 and inspired the important win.
“Everyone was out on their legs, but we really dug in and everyone was referring to the Bloods in ’05-06, so that’s where our real drive was in that last quarter,” Hannebery told afl.com.au after the match.
“We had two guys down in an away game and it just required a huge team effort from everyone out there, so that’s what we were referring to in that three-quarter time break.
“It was a Bloods effort [and] it’s definitely alive. With personnel, it changes year to year, but we’ve got a strong belief in ourselves, a strong culture and we believe our systems work.
“We drew on them in that last quarter and it’s very much alive.”
Hannebery said McGlynn’s effort to put his head over the ball and Moore’s courage running back with the flight set the tone for the Swans’ last quarter, while ruckman Shane Mumford was inspiring.
“Shane had a big challenge on a big ground, and he just works and runs,” Hannebery said.
“He chased blokes down, he spread to space, he made second and third efforts and he used his physicality.
“He’s a sensational acquisition to our team and he’s the sort of guy that’s really driving us at the moment. His last quarter was inspirational for everyone.”
Hannebery was equally important in the final term, winning 10 of his game-high 38 possessions and giving the Swans their midfield drive.
The 19-year-old, who is among the favourites to win the NAB AFL Rising Star Award in his second season, said he was still critical of his game.
“I was pretty scathing today at a few poor decisions I made, so I’m really going to need to work on that through the week,” he said.
“Every single player’s required to do a role week in, week out within our game plan, so I just stick to that, try and put my head over the footy and make some good decisions.”
Saturday’s win reignited the Swans’ push for a home final, with the seventh-placed side level with sixth-placed Carlton on points and one game behind fifth-placed Fremantle.
With games against the Western Bulldogs (SCG) and Brisbane Lions (Gabba) to round out their season, Hannebery said the Swans needed to find consistency if they were to farewell Roos and Kirk with a home final.
“That’s definitely the aim and we think we can do it,” he said. “We’ve got to soak this win up now for the 24 hours and then move on.”
