"What do you reckon?"

With 11 possessions, three tackles and two inside 50s, the 19-year-old will be a walk-up starter for his second game at Spotless Stadium on Sunday.

And the Giants have wasted little time locking away one of their prized assets, extending Kelly's deal for a further two years, keeping him in GWS colours until the end of 2017.

The No.2 pick in last year's NAB AFL Draft, Kelly has given the club a vote of confidence by extending his contract after just one senior game.

"At the moment, everything about the club, I’m just really enjoying my time here," Kelly said.

"We've got a state-of-the-art facility, coaching panel has been great, playing with the boys and just seeing the win (against the Sydney Swans) in round one is something I want to be part of as well.

"It's a pretty exciting time for the club."

Kelly was one of four players to re-sign on Wednesday, with fellow 2013 draftees Cam McCarthy and Jake Barrett, plus key position prospect James Stewart, all extending their deals.

From the moment the Giants were born, there had been an assumption the interstate players could fail to gel in western Sydney and would be keen to return home.

Taylor Adams left for Collingwood in a trade that secured Heath Shaw, while Dom Tyson did the same with Melbourne in the deal that allowed GWS to get its hands on Kelly.

Otherwise the vast majority of Giants have committed their futures to the club, and GWS is keen to see that continue.

"We don't want anyone stealing our players," Cameron said.

"But it’s not just a matter of that; these guys make a decision for themselves.

"Obviously they like what they see. They know we're heading in the right direction, we're a club on the up, and we're becoming more and more competitive, as you've seen in the first two weeks.

"In the end, it's the guys that make that decision."

McCarthy has also extended his deal until the end of 2017, while Stewart and Barrett have signed until the end of 2016.

Stewart has made one senior appearance to date, in round 23 last year, while Barrett and McCarthy are yet to make their debuts.

GWS chief executive Dave Matthews believes the signatures of the quartet shows they have faith in the direction the club is taking.

"It's a testament to all parts of the club, but particularly welfare," Matthews said.

"This club made a decision at the start it was going to invest heavily in welfare.

"We've always said the list rules were only ever going to be as strong as our ability to retain the players.

"So to get them to commit and extend is just an outstanding compliment to the club."

Of all the re-signings, Kelly is the one at this stage that would have drawn the most attention from opposition clubs.

Cameron joked that following his debut, expectations had risen even higher this week for the former Sandringham Dragon.

"We expect him to get 56 possessions this week," he said.

"No, it's fantastic that young kids can start out in the sub rule.

"We bring him in, he plays 45 minutes of footy, we've all seen what he can do and it's likely that he'll start this week.

"He's done his chances no harm."
