MELBOURNE midfielder Brent Moloney says Liam Jurrah's uninterrupted summer has helped him become a player capable of consistently having an impact on results.

Moloney said his high-leaping teammate, who booted five goals in the Demons' 11-point win over the Brisbane Lions, was reaping the benefits of consistent training; something he hadn't been exposed to before his AFL career commenced in 2009.

A shoulder injury halted his progression in the first half of last season, but Moloney believes his form in the late rounds and against the Lions is only a glimpse of what the former Yuendumu Magpie can do.

"He's an excitement machine and he really got us back in the game when we needed a match winner in that second quarter," Moloney said after the match.

"He's a freak.

"It's all about training. When he first got to the club, he didn't really have much of a pre-season, and he had his shoulder at the start of last year that didn't really help him.

"Now he's had a full pre-season and it's really helped him get through games and have more impact in games."

Moloney said Jurrah, who hails from a remote part of Central Australia and arrived at the club with English listed as his second language, was now considered to be "one of the boys".

"He's a real joker around the club and he's just great to have around," he said.

"He's just a funny man and he's a super footballer."

Moloney himself had 37 touches in the win over the Lions but was quick to highlight the efforts of his fellow ball-getters rather than focus on his own achievements.

"I thought all our mids worked hard. It's a team effort and we need everyone standing up in that midfield to drive us and take us forward," he said.

"I thought Jordan Gysberts in his first game was fantastic and Nathan Jones on the wing was good, [Jack] Trengove did his role and Rohan Bail was great on Simon Black, who I believe is one of the best midfielders in the competition.

"There were some good efforts all around the ground."

He also applauded the performance of ruckman Mark Jamar, who racked up 34 hit-outs, 11 clearances and 23 touches in a dominating performance.

"He's been super. He had a super year last year and he's carried on that form last year," he said.

"He gives us midfielders first use and obviously he's dangerous when he goes forward. He was fantastic today."

Senior coach Dean Bailey was less impressed with Jamar's contribution and said his big man needed to work on his consistency from round to round.

"I think Mark set a standard he's got to do every week. He should contribute like that every week," Bailey said.

"He's our No.1 ruckman, I think every No.1 ruckman in the competition is important, and he needs to contribute every week."
