Jackson Hastings has lifted the lid on the secret to Roger Tuivasa-Sheck’s amazing form, revealing the No.1 greets training with the enthusiasm of a little kid in the park.

Tuivasa-Sheck has been one of the NRL’s shining lights this year, breaking the competition’s all-time running record and he appears a shoo-in to be crowned Dally M fullback of the year.

Roosters playmaker Hastings says he has often marvelled at the Kiwi maestro on the field and on the training track this season.

He said Tuivasa-Sheck possessed seemingly boundless enthusiasm and was forever running around practising trick shots which was coming through on the big stage.

“It’s pretty crazy. A lot of people would think that a bloke like that wouldn’t have to train hard,” Hastings said.

“But he’s honestly the first on the field by 20 minutes, running around, chipping for himself, running down the sideline.

“He’s got the most energy I’ve ever seen.

“That reflected in the way he plays and where he’s got to.

“I’ve drawn a little bit from that and I’ve tried to get out there with him and have a little muck around.

“It’s pretty cool to see a bloke like that just running around the park like a little kid.”

Tuivasa-Sheck has come into his own in 2015 after being shifted to fullback following the retirement of Anthony Minichiello.

Coach Trent Robinson said the freedom of playing at the back had injected new life into the 22-year-old’s career.

“He’s a hard worker and he’s diligent about his role,” Robinson said.

“He’s constantly learning and then there’s the freedom to play the way that he plays.

“Combining hard work with freedom is a really good way to play. And that’s what he does.”
