The Roosters had it sewn up once they signed Cooper Cronk.
The Storm are all wrestling tacklers with Slater, Addo-Carr, and Vunivalu, plus Munster, their only potent attacking weapons. Latrell Mitchell, James Tedesco and Luke Keary will slaughter them.
Souths are a 4 man team: 3 Burgess brothers plus Damien Cook. The Roosters have shown that they can handle them easily.
If the Warriors are their opponents only RTS, Shaun Johnson and Bully Luke will trouble the legendary Roosters defence. But the Roosters can contain them and have more fire power.
The Sharks have no chance of getting to the Grand Final without Ben Barba, who is stumbling with injuries at St Helens.
I expect that the Roosters will win the Grand Final comfortably.
