Melbourne will arrive in Sydney ready for a clash of the heavyweights.
Games in the NRL are more often than not won up the middle and on Saturday night the match-up of the two respective forward packs will be a decisive one.
The form of Storm’s big men has been a big reason behind the Club’s 10-2 start to the season.
They will face a stern test against a Roosters side that is playing some much-improved football after a slow start to the year.
“We are expecting a tough, aggressive team. They’ve got a big side from 1-17 and an aggressive forward pack and that is exactly what we are expecting from them, to come out hard, nice and aggressive and take us on through the middle,” Tohu Harris said.
“We are happy with the way we’ve been playing but most of all the way we’ve been defending. If we keep that effort up it will go a long way to performing well against the Roosters.
“We’ve just got to expect a tough game and roll our sleeves up.”
While the rise of Storm’s forward pack may seem sudden, their development has been several years in the making.
“I feel like we’ve taken a huge step forward from the last two years,” Harris said.
“It is something we really wanted to improve on, our play through the middle.
“That has been led by Jess (Jesse Bromwich) and Macca (Jordan McLean). They’ve been huge for us this year and hopefully they can keep us going forward and the rest of us can jump on the back of it.”
