Port Adelaide have secured youngsters Aaron Young, Jarrad Redden, Cameron O'Shea and Jasper Pittard on new two-year contracts, but Travis Boak's future with the club still remains unclear.
Despite the club not having a coach, the re-signing of Pittard, Redden, O'Shea and Young mean Port have now retained seven players aged 25 or younger as they try and build a team to compete with the best in the AFL.
Port Adelaide have also reportedly lured former Socceroos high-performance coach Darren Burgess from English Premier League club Liverpool, although it is Boak's signature the Power would most like to get on a contract.
Boak has yet to reveal where he will play next season, with Geelong considered the highly rated midfielder's most-likely destination.
Pittard has only played one match this season due to injury, having made his debut in 2011, but Port Adelaide's general manager of football Peter Rohde remains convinced the 21-year-old defender will be important to the Power's future.
"Jasper has had to deal with a lot of injury over the last couple of years but no one has ever doubted his talent and how important he is to the structure of our team going forward," Rohde said on Friday.
"We're looking forward to him getting a solid pre-season under his belt so that he has the opportunity to develop into the player we know he can become."
Pittard has revealed he feels a responsibility to Port Adelaide and would like to pay back their patience as he struggled with a hamstring injury sustained in pre-season before fracturing ribs and suffering a collapsed lung during his only game of the year against Melbourne in Round 17.
"Port Adelaide has already given me some fantastic opportunities to develop myself and I'm now looking forward to repaying their faith in me by continually improving and playing some consistent football," Pittard said.
"This year has been a tough year for everyone at the club but I know we're all looking forward to pre-season and I desperately want to be part of our young group that will take this club forward."
Young made his debut this season and the 19-year-old is looking forward to growing with his younger teammates as they make their way in the AFL.
"Port Adelaide is a great football environment to learn and develop as a young player and I've made a lot of close friends in my time here, so I'm delighted to continue on.""Although as a team we've dropped off at times this year, we've also had a number of promising performances and I'm very confident that our young group will stick together and supporters will see us realise our potential sooner rather than later."
