SYDNEY Swans coach Paul Roos has applauded his troops, new and old, after a punishing 20-point win against the Brisbane Lions on Saturday night at the SCG.

The Swans lost Mark Seaby at the start of the game while Jude Bolton and Ryan O’Keefe both played on after suffering mid-game concussions. Young Dan Hannebery also played on after dislocating his shoulder and Ted Richards and Jarred Moore were also injured in the heat of the battle.

While the focus was again on the newcomers after Daniel Bradshaw's booming torpedo goal, Roos said the club’s stalwarts had led the way in the Swans' surge to the top of the ladder after six rounds.

“A lot’s been said, and rightly so, about Bradshaw and [Mark Seaby] and Mummy [Shane Mumford] and Joey [Josh Kennedy] and Benny McGlynn, but our senior players are really standing up,” Roos said.

“They’ve been terrific - [Ryan] O’Keefe and Jude [Bolton] and Goodesy and Kirky, those blokes who have been around for a fair while. That makes a big difference to these guys when they come to the footy club.”

Roos said Seaby (ankle) was likely to face a stint on the sidelines. Moore and Richards will be assessed after rolling their ankles and Hannebery will be examined early this week.

The highlight of the courageous win was Bradshaw's match-turning torpedo goal that Roos compared to another famous moment in the club’s recent history - Leo Barry’s famous mark in the 2005 grand final.

With the Lions mounting a challenge in the third quarter, Bradshaw slotted a booming torp from 60m on the boundary line after the three-quarter time siren.

His goal sent the SCG crowd into hysterics as his teammates flocked from all ends of the field to mob the former Lion.

“It was a bit like when Leo Barry went for the mark in the grand final. It takes courage,” he said.

“Most blokes would have gone back and kicked a drop punt and thought, ‘if it gets touched on the line, it gets touched on the line’.

“Just to actually think your way through that… it’s just smart footy.

“If it goes off the side of the boot, he looks like a goose… but when it goes through, the crowd starts roaring and his teammates jump all over him and everything’s like a fairytale, isn’t it?”

Roos agreed that Bradshaw’s goal was a crucial moment in the game, which the Swans looked to have under control when they led by 42 points during the second quarter.

“They’ve got some real quality and they really came at us. Our guys steadied and it was a pretty critical last two or three minutes of that third quarter,” he said.
