The Mata'utia brothers, 18-year-old Sione and 22-year-old Chanel, combined to score 16 of the Newcastle Knights' 28 points in Sunday's win over the Warriors at Hunter Stadium.
Sione, who was a late inclusion for an injured Akuila Uate, recorded a hat-trick against the sixth-placed Warriors while Chanel crossed in the 68th minute.
Coach Wayne Bennett praised the young siblings for their performance in the six-point win.
“Chanel has had a battle to get to where he got...and he's done it to his credit and has shown us all what he can do,” Bennett said.
"Sione has wonderful attributes, the great thing about him is I imagine one day he'll captain the Knights and he'll be a great player.
“It's a long way away for him but I'm sure one day that's where he'll be heading."
Playing just his fourth game in the NRL, the versatile 18-year-old has excelled in a number of positions.
“Sione's played fullback for us, he's preferred position is centre and he played great on the wing today," Bennett added.
Captain Kurt Gidley echoed the coaches glowing opinion of Sione when asked to describe the young back.
“The first thing that come to mind is toughness, for a young guy,” Gidley said.
“He’s prepared to put his body on the line, and doesn’t have a big head or an ego.
“He trains hard and talks well.
“He’s got all those attributes as a leader, especially around his peers.
“It’s a pleasure playing with the younger guys coming through.”
The Knights travel to Brisbane this week to take on the Broncos at Suncorp Stadium.
