WESTERN Bulldogs defender Dale Morris says his side's backline is finally starting to gel after a topsy-turvy period where players came in and out of the line-up.

The 28-year-old, who is an important cog in the Dogs' usually solid back six, admitted an unsettled start to 2011 for some key players had made the past few weeks hard.

Brian Lake and Lindsay Gilbee had interrupted starts to their season, Easton Wood sustained an injury in round one, Ryan Hargrave remains on the sidelines and Jarrod Harbrow, a star of the side last year, took his talents to the Gold Coast over summer.

However, with Lake and Gilbee playing in round three - and the latter getting a game of VFL under his belt for extra measure on the weekend - and Hargrave nearing a return, he says things are starting to settle. 

"All in all, I think the backline's done pretty well. I'm not sure what the stats say but we're definitely getting used to the new group, which is always a difficult thing when we've had such a settled backline for so long," he told afl.com.au.

"Lukas Markovic was thrown in there and he's done really, really well and played the role that's been asked of him.

"Robert Murphy back there; he played a bit last year and he's doing really well with his drive off the backline.

"Woody was the same before he got injured, so we're another backman down but Brian and Lindsay slotted in really well last round and they'll be better for the run."

The Dogs have also made changes to other parts of their line up with Justin Sherman, Nathan Djerrkura and Tom Liberatore playing their first games in the red, white and blue this year.

With first-year player Mitch Wallis and former Sydney Swan Patrick Veszpremi also nearing their Bulldog debuts, Morris says the energy around the club has been boosted by the new faces vying for a senior game.

"Libba has done exceptionally well with the games he's played and it will be a management type of thing for him being a kid and coming into AFL and adjusting to the work load," he said.

"He brings that energy we talk about, and Justin Sherman is the same. His run and carry that he can provide for the team is something that we're really looking for.

"Just having the fresh faces in the team really lifts the other guys and it's very handy."

Wallis is famously good mates with his fellow father-son acquisition, and despite having stood out at under-18 level more than his friend, has had to watch Liberatore appear in all three of the Dogs' 2011 games from the sidelines.

However, Wallis put in another strong showing in the VFL on the weekend and is getting close to joining his buddy in the team.

"Mitch is knocking all the doors down and doing everything possible to get out there, and that's really good to see as well," Morris said.

"He's not sitting back and waiting for it to happen. He's there on the front foot, putting his case forward, and his time will come, no doubt.

"He's been very close for a few weeks and Libba has taken his opportunity and run with it, and Mitch will do the same thing.

Morris said there had been no jealousy between the boys despite Liberatore's immediate impact at senior level.

"It's a unique position he's in, with his best mate getting a game before him, and I'm sure it must be difficult," he said.

"But, Mitch is a good kid and he was the first one to congratulate Libba, and Libba will be the first to congratulate Mitch.

"They've got a really good bond, playing with each other for so long, and it's good to have that competition in the team and have everyone fighting for spots."
