Trengove was a surprise inclusion in the player-elected leadership group when it was revealed before Christmas.
The 20-year-old has played just 19 games since slipping through to the Power with pick No.22 in the 2008 NAB AFL Draft and is the youngest-ever member of the leadership group, which this year includes incumbent skipper Dom Cassisi, Dean Brogan, Travis Boak, Troy Chaplin, Alipate Carlile and Jay Schulz.
Chaplin said the utility had earned the respect of the players and deserved the honour.
"Jacko's someone that doesn't take any crap from anyone whether it be from Chad Cornes or the youngest player on the list. He tells it how it is…and for him to be in the leadership group at 20 years of age is a big tick next to his name," Chaplin said.
"Hopefully, Jackson, Trav Boak and Hamish Hartlett can lead us in the years to come. No doubt they're captaincy material but they've still got a bit of work to do."
Chaplin has been recalled to the leadership group after a brief stint early in his career.
The 24-year-old was elected to the group and touted as a future captain of the club three years ago but found the demands of the official role detrimental to his on-field performance and opted to take a step back in 2009 to focus solely on football.
Chaplin said the experienced members of the leadership group would work closely with Trengove to make sure the new role didn't interfere with his development.
"Jacko started playing regularly towards the end of last season and found his feet pretty quickly. He's a pretty level-headed guy and he's got some experienced guys around him, who can pull him aside if need be," Chaplin said.
"For me being in the leadership group was a bit of a distraction a few years ago and I was probably trying to take a bit too much on outside of football but you grow up and you mature and learn to deal with things.
"It's a good challenge to be back in the group this season and I'm looking forward to the year."
Trengove failed to play an AFL game in his first year at Alberton because of a serious knee injury, but made an encouraging debut against North Melbourne in round one last season.
The competitive big man earned a NAB Rising Star nomination for his 23-possession game against West Coast in round 20 and took out the Gavin Wanganeen Medal for the best Power player under the age of 21.
Trengove said his call up to the leadership group had come as a "massive surprise".
"I was very happy to take on a new role and I don't think things will change too much from what I was doing last year because I've still got a lot of improvement to come in my football," Trengove said.
"I think it's going to be the older guys in the leadership group that take most of the control but when I do need to step up and do something, I'm sure I'll be able to do it."
Trengove is out of contract at the end of the season and is likely to attract the attention of Greater Western Sydney's recruiters but the tough Victorian said he had no reason to leave Port Adelaide.
"This club has been fantastic to me," he said.
"It's pretty early in the year to be talking contracts but I'm sure that will take care of itself during the year."
