PORT Adelaide has landed exciting NAB Under-18 All Australian midfielder Jake Neade and South Australian defender Jack Hombsch from GWS in exchange for pick No.29 at the NAB AFL Draft.

The signings ensured the Power made significant ground on Tuesday after the recent losses of Troy Chaplin and Danyle Pearce during Gillette AFL Free Agency period.

Northern Territory star Neade was awarded the Harrison Medal as division two's best and fairest in this year's national championships after being named the Thunder's best player at last year's titles.

He was able to be traded under the Giants' list establishment zone selections.

The 18-year-old possesses superb endurance - he has a personal best of 15.1 in the beep test - as well as speed, running a 2.96-second 20m sprint at the NAB AFL Draft Combine.

At 170cm and 64kg there's not much of him, but his senior coach at St Patrick's College in Ballarat, Howard Clark, said size had never been an issue for a kid he described as the best tackler he had coached.

"Jake, as a pure footballer, is extremely clever," Clark told AFL.com.au.

"He's got an innate ability to get himself out of congested areas and I think in his entire time here at the college, three years, he hasn't played in a losing side.

"The impact Jake has had on our football program has been profound.

"His tackling technique is as strong as anyone I have coached. Although Jake is small, much larger opponents can’t break through his defensive work."

At St Pat's, playing alongside other draft hopeful Dominic Barry and Nick Rippon, Neade starred as the side won its third straight Herald Sun Shield premiership.

Neade and Rippon are the only two players who have played in all three wins.

Clark issued a glowing assessment of Neade, not just as a terrific footballer, but as an upstanding and "most respectful young man".

"He's become a very, very important person in my family and I know he's had a similar impact on a lot of other people in our college and also at the North Ballarat Rebels," he said.

"He's just an outstanding person … everyone involved at both programs, St Pats and the Rebels, will be equally proud of him."

Port Adelaide football manager Peter Rohde said the club was very impressed with Neade's speed and endurance along with his work ethic as a pressure forward.

"Jake was rated highly in this year's under 18 championships for his pressure acts so we're delighted to have him here at Alberton," Rohde said.

"We identified him early as a small forward who can kick goals and apply plenty of defensive pressure and we look forward to his journey and development here at Port Adelaide."

Hombsch, 19, will return home to Adelaide after he joined the Giants from Sturt as one of its pre-selected 17-year-olds in 2010.

He is seen by the Power as a possible direct replacement for Chaplin, who joined Richmond as a free agent.

Rohde said, "We've followed his progress over the last couple of years and part of the decision in allowing Troy Chaplin to return to Melbourne was that we see Jack as being a long-term, strategic replacement.

"Jack's main attributes include his running ability, his ability to drop off and take contested marks and his kicking from defence. He'll certainly have the ability to play on the opposition's tall forwards."

The 194cm key defender played seven games for the Giants this year, including a 19-disposal effort against West Coast in round three.

By acquiring pick No.29 at the NAB AFL Draft, GWS strengthened its grip on the first two rounds of selections and now have picks 1, 2, 3, 12, 14 and 29.

The club's football manager Graeme Allan thanked Hombsch, one of the club's founding players, and said his move to the Power would result in more game time.
