THE DESIRE and hunger of Port Adelaide's senior players is as strong as ever after signing long-term contracts, midfielder Hamish Hartlett says.

Hartlett is one of several of the Power's experienced contingent to have committed his future to the club.

Last year, the 25-year-old penned a five-year extension until the end of 2021 to keep him away from the clutches of rivals during free agency.

It's a similar story for captain Travis Boak, star forward Chad Wingard and dual best and fairest Robbie Gray, who are signed until 2019.

Hartlett told AFL.com.au that having the security of a long-term contract didn't translate into standards slipping.

"We have no complacency in terms of our personal performance, whether we've got long-term contracts or short-term contracts," he said.

''That's not the mindset we've got.

''We've got a lot of guys who love this football club, they love the environment that's here and want to do everything possible to make sure we have success at this club."

The Power have won three of their first six games ahead of Sunday's clash with the Brisbane Lions at Adelaide Oval.

After thumping losses to Greater Western Sydney and Geelong, the Power bounced back with an emphatic victory against Richmond last weekend.

''We've really simplified what we expect of each other over the last week or two," Hartlett said.

''You're in the team to play a specific role and if you get that role right and you get the job done in your area, you'll keep playing games of footy.

''It's the guys who lose sight of that and try and do their own thing that will find themselves out of the team."

Hartlett missed two weeks with a hamstring injury and is slowly starting to regain his excellent form of last season.

The Power are showing glimpses of the exciting attack at all costs philosophy that was the hallmark of their finals run in 2014.

''From game to game, it might differ from when you can go into the corridor,'' Hartlett said.

''Some games you might be able to get in there early on if the opposition's defence isn't as tight as it should be, and in other games it might take two or three quarters to get the game on your terms and get the ball moving the way you want to.

"We want to try and go there and play the style of footy that we have been for the last few years."
One of the changes for their match with the Tigers was getting more run and carry out of defence.

"Our running ability is a real key for us and we can have an edge over the opposition if we can get that part of our game right," Hartlett said.

''We played a smaller, more mobile backline and it may have helped with our ball movement.

''There were a couple other things we've fixed up over the past two or three weeks that has helped us get back on track."
