The Sydney Swans will unleash twin turbos Lewis Jetta and Gary Rohan on Saturday with the hope they can finally become the dynamic duo expected when they were drafted together more than four years ago.

 Rohan was taken with the sixth pick in the 2009 NAB AFL Draft, with Jetta nabbed at No.14, as the Swans immediately achieved a stated aim of injecting some pace into their traditionally workmanlike line-up.

 Since that time, however, the pair has made just 20 appearances together, including a measly six over the past two years.

A potentially lethal attacking force featuring two of the quickest players in the AFL, it is still yet to get going, but will be on display when the Swans take on Greater Western Sydney at Spotless Stadium.

"We've thought about it often, trying to get the two playing more together," Swans coach John Longmire told AFL.com.au.

"It's what we thought about when they first turned up at this footy club – get them playing as much footy together as possible and have that speed on the outside to complement our inside, contested ball players.

"And we've very rarely had it.

"I'm hoping we get a good run and those two get a good run at it now."

Rohan's troubles have been well documented, with his broken leg suffered in round four, 2012, severely impacting his young career and adding to a string of injuries that have kept him to just 27 games to date.

But the 22-year-old has enjoyed a solid pre-season and just last month extended his contract until the end of 2017.

Longmire hopes Rohan will have a breakout 2014 and finally start to fulfil his potential.

"We knew we had to get some speed into our team and it's one of the few times we've had the high draft picks," Longmire said of that 2009 draft.

"We had pick six that year and (Swans list manager) Kinnear Beatson just loved Gary and we saw from the moment he turned up how explosive he was.

"If he's able to get a good, strong run without injury, I'm sure he'll be able to play some really good footy for us."

Jetta was one of the real success stories of the Swans' march to the 2012 flag, kicking a team-high 45 goals across some scintillating performances to establish himself as a star of the competition.

But his 2013 campaign never got going, starting off with some indifferent form before a shin issue forced him to miss half the season.

A minor knee operation in January then interrupted his preparation for the coming year, but Longmire is confident the 24-year-old can get back to his best in 2014.

"He had an operation, an ITB release, and that set him back about a month," Longmire said.

"But he's come back from that really well. It was a good decision to operate on him because the medical staff didn't want it to linger on during the year.

"He helps change the way we play and missing him so much last year, we really felt that as a team."

Another Swan making good progress is key forward Kurt Tippett.

Ruled out of round one some weeks ago as he deals with tendonitis in his knee, alarm bells were ringing this week when Tippett was listed as facing another three to four weeks out on the club's injury update.

But Longmire insists he is improving and should be pushing for a spot in the team in the coming weeks.

"The reality is it changes all the time, as we found last year," Longmire said.

"There were plenty of players we said might be two or three weeks and they ended up being out longer than that.

"Kurt is back running. Is he a chance for the second game against Collingwood? It'd only be a small chance.

"But he's coming along really well and what we do know is he's able to play off a limited preparation and the role that he plays in our team allows for that.

"We hope to get him back in the team as soon as we can."
