With a crowd in excess of 70,000 anticipated for the all-Sydney showdown, Maguire said his young stars were handling the expectation of the big week impressively.
"The boys in our group like Roy Asotasi, Michael Crocker, Matty King, Greg Inglis, Sam Burgess I could go on on a number of players," Maguire said.
"Even Luke Burgess has played in a number of finals overseas. We're lucky that we've got a lot of experience at this time of the year and the young boys are just thriving on the enthusiasm."
Maguire confirmed that winger Nathan Merritt was on track to return from a shoulder injury that forced him to miss last week's victory over Canberra.
"We're really hoping he's right to go. He's trained all this week so there's no reason why he shouldn't be playing," Maguire said.
"As a team we want Nathan in there. He's a massive part of what we've been doing here."
Should Merritt fail a late fitness test however, the versatile Justin Hunt will take his spot as he did against the Raiders.
