Yep. I'm of the view that the best strategy to adopt in sport is to find a way of playing that the opposition can't live with and make them change. Now that's easier said than done, but an awful lot of good teams have been able to do it over the years. Just because you know what's coming doesn't mean that you can do anything to stop it. That's ideally where I'd like our play to go, imposing ourselves on the opposition.
Izzy at fullback is an example of this: he's imposed himself so much in that position that other teams are actively keeping the ball away from him.
We had it with George Smith, Latham, Larkham etc. All the greats, and great Wallaby teams, were full of players that the opposition had to change their game plan to nullify.
If you have 3-4, then suddenly you've got a team which the opposition CAN'T plan against, because planning against one player gives another player the opportunity.
Eg Folau/Cooper. Folau is so dominant that teams are now trying to outrun us, which plays into Cooper's hands because the game becomes less structured.
NZ do it with Carter and their plethora of outside backs, but usually Dagg and Jane. Carter would pin us down with his kicking game, keep us under pressure, and we had two options: try and run it or kick. Running usually meant turning it over and opening us to counter-attack, and kicking would give Dagg and Jane what they wanted; broken field kick returns.
The only way to beat that, would have been to play someone who could out-kick Carter, or at least match him with tactical kicking. Now, if only we'd had someone who could do that
