GREATER Western Sydney coach Kevin Sheedy has predicted four of his first round draftees will play in the Giants' first match on March 24 - and former Sandringham Dragon Liam Sumner will do everything he can to be one of them.

Sumner, 18, was picked by the Giants with selection No. 10 overall - their eighth choice.

And the agile midfielder said Sheedy had already impressed the young group with his humour.

Sumner said the coach's remark that just under a third of the Giants' first-round acquisitions would likely play in the club's inaugural AFL game made him even more determined to ensure his pre-season was important.   

"It's a bit of motivation but you've got to put in the effort to see where you end up," Sumner told AFL.com.au.

"There's a lot of other boys competing against you, going for the same spots so I've just got to do my best now."

Sheedy believed a handful of his young first rounders from Thursday night's NAB AFL Draft would be ready to go when the Giants faced the Sydney Swans at ANZ Stadium in round one of the home and away season

"I have no idea [how many could play]. Probably four," Sheedy said on Friday, as the 11 young players got to know their new training ground at Blacktown International Sports Centre.

"In fairness to them, we only have 10 weeks to train these young men, and it's not a lot of time coming into the NAB Cup. Then we'll find out how their performance is.

"It's great to play a person when they're ready and not because they've been drafted yesterday.

"If you play a person too early, it could do a lot of harm to their confidence and their career, but if you play a person at the right period of their maturity, then you could get a performance like Dustin Fletcher, who played in year 12 in a Grand Final and he's coming out to play his 20th year.

"It's about the person more than the selection."

Sumner said playing in the Giants' first home and away game was his sole focus after achieving the dream of being drafted on Thursday night.

"It would mean the world to me, it would mean everything," he said.

"It would mean all the hard work I've put in already will have paid off, although it has already just getting to the club but there's still so much to go.

"It's a new world, a new level and I've got to step up to it."

Sheedy said he had no issue with giving young players their opportunity to play, but only if they were ready.

"We'll pick the best side we can pick. These guys will say I'm going to play and have my performance on the board, and most players in the history of time select themselves," he said.

"We just put the note through to the press. Most players, 90 to 95 per cent of players select themselves, and whoever puts their hand up, I have no problems playing young players.

"They helped me win a premiership in '93."

Sumner said he was thrilled and surprised to have been selected at pick No. 10 after expecting to fall "somewhere between 13 and 20".

"We were all sitting down and they said the top 10 were sitting in a separate part, and I thought they were more over to the right," he said.

"But then my name was called and I was stoked. As soon as it got read out, my heart jumped and it was like a dream had come true."

His parents Paul and Sue were with him on Thursday night, and the family will travel home to Melbourne on Friday to help him prepare for his move north on Sunday.

Sumner will live with No. 1 draft pick Jonathon Patton - who he played with in this year's Vic Metro team - at Breakfast Point.

"We played against each other in the TAC Cup but then we played together in the national carnival, and I roomed with him a couple of times there," he said.

"He's a gun and I can learn a bit from him. He's unstoppable, I reckon, and he'll attract some of the best defenders in the League."
