Roberts clear on role

After featuring in Melbourne's last 10 games, Storm pivot Ben Roberts is clear on his role and what he needs to do for Craig Bellamy's side.

The 29-year old playmaker began the season swapping between Storm's starting NRL 17 and reserve grade in the NSW Cup but has since held his halves position partnering with Cooper Cronk and on occasion Ben Hampton.

"I think for me it's about doing my job and doing it well," Roberts said.

"That's one thing I've worked on all year, being very clear with what my job is in the team.

"For me that doesn't change, I've got a job to do and I'll go out and do it on the weekend."

Playing and training alongside Cronk as well as other experienced playmakers such as Cameron Smith and Billy Slater, has provided an incredible learning experience for Roberts.

This year I've learnt so much that I could learn in two years," Roberts said.

"I'm pretty much like an open book, I'm trying to take down as much as I can from these guys."

Roberts echoed the thoughts of his coach and teammates throughout the week, confirming he and the rest of the side were eager to make amends for last weekend's loss and bounce back onto the winner's list against the Sharks.

"After the way we had played in the last month we sort of let ourselves down with the result and the way we played last weekend," Roberts said.

"We just need to get back to that good defensive record we had over the last month.

"We thought it was an attitude adjustment that was needed, we've discussed that and worked on it this week, hopefully we can go out there and perform well."
