Jake Trbojevic was man-of-the-match in the Blues' 38-6 State of Origin II win after producing a brilliant 73 minutes in the middle, while younger brother Tom raced in three tries in just his third match back from a hamstring injury.

The brothers' current three-year deals at Manly run through to the end of 2020 and are worth $2.1 million and $2.7 million respectively.

The Sydney Morning Herald understands Jake will earn just under $900,000 in the final year of his current contract with Tom, who was unlucky not to win the Wally Lewis Medal for player of the Origin series last year, to collect more than $1 million next season.

Rival clubs can table offers from November 1, provided there are no contract extensions signed in the meantime.

In their prime years and producing on the biggest stage, both players are tipped to be in serious demand.

"Tom and Jake and their brother Ben would love to be Manly boys for their careers, but you'd also be naive to think there wouldn't be any interest from elsewhere," said their agent Paul Sutton.

"They love playing together and they'd love to stay together, but if things panned out where they couldn't, they'd have to consider it."

Sea Eagles fans would not begrudge the Trbojevic brothers and Manly captain Daly Cherry-Evans tying up virtually a third of the club's salary cap.

With those three at the club, it is not the wildest suggestion Manly could push for a title under Des Hasler in the next three years.

Kangaroos coach Mal Meninga has enjoyed working with the Trbojevics and was part of the panel who gave Jake the nod over Tom for the man of the match award at Optus Stadium on Sunday night.

Meninga even suggested Jake was helping reshape the way the game was played.

"To play 73 minutes at Origin level in the position he played was extraordinary," Meninga said.

"The decisions he makes through the middle are generally on the mark and defensively he's outstanding.

"He's become a smarter player, he knows how to get through a game now, and in a way he's changing the way No.13s play. It's like having another member of your spine in your team. They can make you yards, get you a quick play-the-ball but also create in that middle third.

"I think all clubs are aspiring to have a ball-playing No.13 with the way the game is evolving. When your middle is sometimes vulnerable when fatigue happens, when you've got a player of his ilk with his smartness, he can open up a game for you. He can be a match winner through the middle.

"And with Tommy, you just play him. I think he enjoys playing centre, I think he thinks he's a centre at times. Because of the extraordinary talent in that fullback position and with 'Teddy' [James Tedesco] being outstanding, having Tom on the wing or centre is very helpful."

Manly icon Bob Fulton loved Sunday night's performance and said of the Sea Eagle superstars: "The two brothers are polar opposites in what they contribute to any team they play in.

"Jake plays in the middle and helps to lay the foundation and does that very effectively.

"And Tommy is as brilliant as any player in the game and like Jake has a serious football brain. Combine that with his freakish traits and you have the complete package."

Tom was delighted to be back in the Blues fold after missing game one with a hamstring injury.

A fullback by trade, he said he was more than happy to spend the remainder of his representative career in the centres or on the wing, especially with "the best player in the world" Tedesco NSW's current No.1.

His combination with Tedesco was sensational and the ploy to bomb Kalyn Ponga with a taller Trbojevic in pursuit worked a treat for the first try. His support play down the middle with Tedesco led to his second and third try.
