Trent Robinson issued a bittersweet prediction that Roger Tuivasa-Sheck was only going to get better as the Sydney Roosters maestro wrote his name into the NRL record books.

Tuivasa-Sheck set a new benchmark for the most running metres in a season with a monster 268-metre effort in Saturday’s 12-10 win over Brisbane.

He passed his Roosters No.1 predecessor Anthony Minichiello’s 2004 mark of 4590m as he took his tally to 4717m with two rounds remaining.

He also became the first player since records started being kept in 1999 to run for 250-plus metres on five occasions and eclipsed Jarryd Hayne’s 2009 mark for most 200-plus metres games in a year with 11.

Robinson was in awe that Tuivasa-Sheck has set so many new records all within 24 rounds.

The Roosters coach says we haven’t seen the best of the 22-year-old but he made the prediciton in the knowledge Tuivasa-Sheck will leave Moore Park at the end of their 2015 campaign.

It would pain him to know that one of his players has blossomed into one of the game’s best attacking weapons at a time he was winding up his stay in Australia.

“This will sound funny but I think Roger can get better than where he’s at the moment,” Robinson said.

“But that running record, the way he brings the ball back, it’s changed the way that we attack out of the back field.

“It’s been enormous the way that he’s carried. And he doesn’t have an off-switch when it comes to carrying the ball.

“We had two (carries) in that corner – Dylan Napa had the first one and Roger had the second to get us out of trouble. They were huge plays.

“Roger works so hard. Setting that record after round 24, he’s learnt some things off Mini and pushed his limits.

“I still reckon Roger’s got some (improvement) in him as well.”

One of the highlights of the night was a monster step that Tuivasa-Sheck put on Brisbane captain Justin Hodges.

The Australian three-quarter compared him to livewire greats Preston Campbell and Matt Bowen and revealed he was an unabashed fan.

“He’s good on his feet,” Hodges said.

“I love watching him play, he’s a freak of a player.
