Finn Maginness could be the father-son pick that finally works for the Hawks and makes an instant impact next year, according to the club's national recruiting manager Mark McKenzie.

Maginness is the son of dual premiership-winning Hawthorn defender Scott, who played 131 games between 1988 and 1996.

Hawthorn matched North Melbourne's second-round bid for Maginness to see the son-of-a-gun officially become a Hawk on Thursday night.

Maginness was potentially touted as a top-15 pick, but ultimately fell to number 29 to the Hawks after North Melbourne's unsuccessful attempt to nab him.

The Hawks matched the bid with picks 51 and 54, and received Maginness and selection No.71, which pick 71 was passed on to prepare for the pre-season draft.

"Finn's a great character, his family is great, and we're just very happy to bring him into the football club," McKenzie told reporters.

"It's been a bit of a long process but he's really improved as a player, especially over the last 12 months and I think we saw his (outstanding) combine results – he deserved everything he's received so far."

Maginness is just the fourth father-son selection made by the Hawks in the club's history, with Steven Greene (2000), Travis Tuck (2005) and current Swan Josh Kennedy (2006) as the other selections.

None of the father-son selections for the Hawks have played more than 42 games for the club, but the expectations for Maginness are far greater.

Maginness' playing style has been compared to that of Josh Kennedy's, with both being hard nuts and both standing at 189cm.

Maginness averaged 21 disposals per game for the Sandringham Dragons and played well enough to earn a selection into Vic Metro's squad for the AFL Under-18 Championships.

The teenagers outstanding draft combine results really put him in the spotlight.

He placed sixth in the 20m sprint, equal-seventh in the Yo-Yo test then second in the 2km time trial – stopping the clock at a slick 5:51, which was 13 seconds quicker than the previous record.

Young gun James Worpel has been the most recent Hawk to shine bright and become a senior regular, and McKenzie said Maginness' athletic qualities could lead to a follow-on just like Worpel.

"He's got the size and the running capabilities (to slot straight into the senior side) but there's no rush," McKenzie said.

"We're not necessarily drafting for the next 12 months – it will be the next number of years."
