PORT Adelaide ruckman Jackson Trengove has taken exciting small forward Jarman Impey under his wing to help get his life back on track.

Impey crashed into four cars and fled the scene after a drinking session with Power teammates in December.

The remorseful 21-year-old – who lost his father to cancer last year – has impressed during pre-season training and in the Power's opening JLT Community Series game against St Kilda last week.

"Since the driving incident, Jarman has really changed his life around," Power assistant coach Brendon Lade told AFL.com.au.

"He's living with Jackson Trengove and they're really close and doing a lot of things together.

"Jacko was a bit of wild child back in his day as well, so it's probably a good mix, to teach him some lessons early in his life.

"They've got a really good relationship.

"Jarman's always upbeat, he's never down and once he knows you and he likes you, he gets around you and he's a really good kid to have around the club."

Impey and teammate Aidyn Johnson, who was in the car with him at the time, have been suspended for the Power's round one clash with Sydney at the SCG.

Trengove is in the Power's leadership group and is one of the most respected players at the club with his work ethic.

The 26-year-old was on the training track with the club's first-to-fourth-year players for the start of pre-season training in November, even though he wasn't required for another two weeks.

Off the field, Trengove is an ambassador for Brain Injury Australia and is involved with the Childhood Cancer Association.

Impey switched from the backline to attack last season, using his pace to put pressure on defenders and keep the ball inside the forward 50.

"We've made it really simple for his role this year," Lade said.

"Kept it very, very basic with what he needs to do and what his main objectives are.

"He's really enjoyed that.

"It really suits him at the moment and we're looking for him to take that form through the pre-season through the whole year."
