The Roosters put on a clinical showing on Friday night, defeating the South Sydney Rabbitohs 30-0 at Allianz Stadium.
They had an early nervous moment when Sio Siua Taukeiaho dropped the ball from the first tackle, but it was defended well, and the Roosters would claw their way back up the other end within minutes.
The opening twenty minutes were outstanding for the Roosters, scoring four tries.
Their first try was through Michael Jennings, who put the foot down to burst through the defence and score on the left edge.
Their second was scored through Blake Ferguson, after collecting a near perfect kick from James Maloney to plant it down.
The third was scored through Cordner, taking advantage of a loose ball, with the fourth try awarded to Captain Jake Friend on the back of a freakish offload from Cordner.
They would score again in the final five minutes of the half through Aidan Guerra, on the back of a nice Tuivasa-Sheck pass to put him over.
The Roosters lead at the break was five converted tries.
The second half saw the Rabbitohs turn up in a big way, with desperate attack that had the Roosters constantly defending their line.
The Rabbitohs had plenty of energy with the ball, but the Roosters were defending what was being thrown at them.
There was some unattractive football played, but it was entertaining.
Late in the second half the Roosters had a moment of complete brilliance, when Tuivasa-Sheck wrong footed an opponent in-goal, passed to Daniel Tupou, he sprinted up field, offloaded to Jennings, back to Tupou, out wide to Aubusson, but he was tackled just short of the line.
They looked certain to score with just five minutes left on the clock, but the video referee ruled that Jackson Hastings knocked on in-goal after running a near perfect line.
The Rabbitohs fought hard for points in the second half, but the Roosters defended it.
Not just keeping the Rabbitohs scoreless, but claiming their third consecutive Minor Premiership, the Ron Coote Cup and their 12th straight win.
