Whichever team deals best with the opposition's brilliant fullback will win Sunday's grand final.
I'm expecting the Storm to test out Ben Barba with a barrage of bombs early on. Teams haven't done that to the brilliant Bulldogs match-winner much this season, but we've seen in the past he can be susceptible to pressure under the high ball.
Getting to Barba early and eroding his confidence will help to limit his threat, so I'm sure that will be a big part of the Storm's game plan.
On the other side of the equation, if they are to nullify Billy Slater's threat from those brilliant Storm set pieces the Bulldogs must control the speed of the ruck and win the field position battle. If the Storm get a good roll on and play at the right end of the field then Slater is deadly.
Cameron Smith is the architect of everything for the Storm. He and Cooper Cronk are the best kickers in the NRL. Shutting down that kicking game is incredibly hard. In grand finals territory is always crucial. To negate the Storm's kicking advantage the Dogs must command the ruck and win the wrestle. Their best chance of doing that is to stick to the way they have been playing all season.
