It is very close but only 3 teams -- Sydney Roosters, Melbourne Storm, and New Zealand Warriors -- have the brilliant players necessary to win a Grand Final.
Sydney Roosters have Latrell Mitchell and James Tedesco, Melbourne Storm have Billy Slater and Cameron Smith, New Zealand Warriors have Shaun Johnson and Roger Tuivasa-Sheck.
Cronulla Sharks have only one brilliant player in Valentine Holmes, so he can be contained.
South Sydney are all muscle (Burgess boys) and a little zip (Damien Clark) which can be contained.
