Roosters punish woeful Broncos at the SCG

The Sydney Roosters have flexed their muscle with a 36-4 flogging of Brisbane which will raise questions about the Broncos' much-vaunted young pack and new coach Anthony Seibold.

The Roosters were dominant from start to finish in a seven tries to one thumping as they recorded their first win at the SCG since 1999, and their biggest ever win over the Broncos.

Even without enforcer Jared Waerea-Hargreaves (ribs) and hooker Jake Friend (shoulder), the premiers bullied the Broncos, who only had themselves to blame after repeatedly turning the ball over.

Coming into the match, all eyes were on Broncos star Tevita Pangai Junior, who was said to be in the Tri-Colours' recruitment plans as he prepares to come off contract next year.

However, he gave a reminder of the deficiencies in his game after he was put on report for a late hit on Cooper Cronk which was labelled a "dog shot" by Immortal Andrew Johns.

"It's a dog shot, an absolute cheap shot. It's so dangerous, someone is going to get really seriously injured," Johns said in the Channel Nine commentary.

Cronk was playing his first game back after a two-week lay off with a hamstring injury and came from the field in the 53rd minute with a back problem after a heavy collision trying to tackle Corey Oates.

The Roosters put the icing on the cake with a scintillating Joey Manu try in the 78th minute during which the ball was kicked three times and went through eight sets of hands.

The Roosters had 71 per cent of the ball in the first half and that weight of possession told in the end as the Roosters forwards, led by Sio Siua Taukeiaho (211 metres), dominated.

It leaves the Broncos at 1-3 and Seibold will now be feeling the heat after his side were pegged as premiership contenders.

The Roosters opened up a 22-0 lead at halftime with most of their points coming directly off Broncos errors.

After Jamayne Isaako was bundled into touch close to his own line, Angus Crichton powered over Anthony Milforrd to make it 10-0.

Jack Bird bombed a rare golden opportunity late in the first half and the Roosters then ran downfield and Daniel Tupou outleapt everyone to score.

Matt Gillett got the Broncos on the scoreboard in the 55th minute however the Roosters ran home with a wet sail, running in tries through James Tedesco, Mitchell Aubusson and Manu.
