Wayne Bennett’s ability to make his young rookies believe has the master mentor sitting on the verge of one of the greatest feats of his 44-year coaching career.

Queensland’s’ series-opening 18-14 win over NSW on Wednesday night was State of Origin’s biggest upset in more than 20 years, while an even bigger boilover looms if the Maroons lift the shield in Sydney.

Bennett is already arguably the greatest coach of all-time, with a record seven grand final wins to go with his five Origin series victories.

Maroons rookies were quick to speak in awe of the 70-year after the win, where Queensland came from 10-0 behind at halftime to shock the Blues.

“As all good coaches do, he’s got that respect among the players,” said fullback AJ Brimson, who scored a try on debut.

“Especially someone like myself, I looked up to Wayne a lot growing up.

“Just to be coached by him, everything he says you are locked in and focused you don’t want to let Wayne down.

“I think he gets the best out of his players.”

Brimson admitted to being nervous meeting Bennett, before the veteran quickly settled the rookie into camp.

Bennett’s coaching accomplishments are vast.

His effort with nine Queensland debutants in 2001 is considered one of the Maroons’ greatest Origin series triumphs, along with Paul Vautin’s 1995 side.

At club level, Bennett’s masterstroke to help Brisbane to the 2006 premiership with Shane Perry at halfback is widely regarded as his finest hour.

But if the Maroons clinch one of the next two games to take the 2020 Origin series, it will almost certainly torpedo those.

Particularly when you consider Bennett had just one month of planning behind him, working with 20 players in Queensland’s squad he’d never coached before.

“I was proud of them,” Bennett said.

“I wasn’t worried about the self-belief. They put a maroon jersey on and they know the expectation that comes with it.

“They trained excellently for 10 days, I knew that self-belief wasn’t going to beat them tonight.”

Meanwhile Brimson said he would have no issue being switched to the wing for Game II in Sydney if Bennett wants to play Valentine Holmes at fullback.

Holmes will return from a suspension and offer much-needed experience to the Maroons’ backline, however Brimson was solid at the back while still looking dangerous in attack in Adelaide.

“I’ll leave Wayne to make the tricky decision,” Brimson said.

“Obviously Val has proven himself at the Origin arena, so I assume he will be back somewhere. Whether that will be at fullback or wing, I’m not too sure.

“I will play anywhere. That was the best feeling ever (on Wednesday night), so I will play anywhere.”
