Greater Western Sydney will be one of the clubs to benefit the most if a cap on the number of interchanges is introduced next year, vice-captain Tom Scully says.

A proposal to cut the high amount of rotations has generated widespread concern throughout the AFL, but Scully believes it could be an advantage to the competition's youngest team.

''I'd be pretty happy with that rule coming in,'' Scully said.

''We've got a lot of great endurance runners in our team, so I think for us personally as a team we wouldn't be too disappointed with it.''

The rule has been trialled in the pre-season NAB Cup competition, with a limit of 80 rotations to be enforced in Friday night's match between the Giants and Essendon at Manuka Oval.

AFL chief executive Andrew Demetriou said this week that a cap would definitely be applied for the 2014 premiership season, although how many interchanges would be allowed has not been finalised.

The Giants could be the major winners if a cap gets the green light for next season, given their extremely young list and lack of physical size.

''It'd be interesting to see if it does come in how training regimes would have to change to play and adapt and play more game time,'' Scully said.

''Speaking to a few of the boys they've found it pretty tough.

''If the rule does get brought in it's probably going to change the game a little bit.

''I suppose it's almost going to be a tactic of how many times you use your rotations and how many times you rotate.''

The Giants exceeded all expectations in their debut season and have been competitive so far during their pre-season campaign.

They will welcome another youngster into their ranks when No.2 draft pick Jono O'Rourke makes his debut against the Bombers.

The 18-year-old midfielder starred for Vic Metro at last year's under-18 national championships and was rewarded with All Australian honours.

Veteran ruckman Dean Brogan will also play his first match of the year, coming into the team alongside co-captain Phil Davis, Setanta O'hAilpin, Curtly Hampton and vice-captain Scully, who missed last week's game with the Lions with a knee injury.
