The Tri-colours looked every bit the reigning premiers in their 32-12 win over the Melbourne at AAMI Park on Sunday.
In contrast, the Storm missed 41 tackles as the Roosters' gorilla forward pack proved the difference.

After a slow start to the year, the Roosters are firing now with six wins from their past seven outings.
Sunday’s win placed then in the top four with a home game to come against the Knights next Saturday night. It is a turnaround Robinson puts down to two key factors.
“The physical development we’ve had during the season, we are getting to he point where we are really strong and fit,” said Robinson.
“The second thing is to focus on all parts of life that goes to becoming a professional footy player.
“I think they are the two things we’ve done really well and we are improving at.”
Robinson also praised the rule change on the corner posts after some Roger Tuivasa-Sheck brilliance in the second half. The brilliant youngster showed his class when he put his blistering footwork on display to dazzle two Storm opponents and reach for the line.
The try was referred, with the replay showing Tuivasa-Sheck touching the corner post before grounding the ball. Under the relatively-new rule, the try was allowed and the moment celebrated by the travelling Rooster fans.
“That is pretty normal for Roger to do that, he does it so often,” said Robinson.
“The new rule with the corner post, I think it’s been spectacular for our game that it is not a part of the touchline in that try scoring movement, today was another example of that.
“That is a change of the rules that has added some excitement to our game.”
