It's nothing like that at all. Cameron Smith isn't a dynamic player like Luke is. Smith directs a team around the paddock, he's the kind of guy you want on the field for 80.
Would Luke really make the side ahead of Cameron Smith? I don't think so simply because Smith is such an important player with his general play kicking (and goal kicking) somthing Luke can't do.
No one will take Cam Smiths hooker role from him unless he is injured. Luke would easily make the aussie side as a utility player...
Luke is a dynamic player, but like i have said previously, he has now evolved as a guy who directs his forwards where he wants them.. And he does have a decent kicking game on him, its just that souths are poorly coached and rely on two of the worst kickers in the NRL (suttons bomb is good though).. And Luke is a part time goal kicker too come to think about...
There was a game this year when luke was forced to take the halfback role for a part, and when he did, they immiedatly put on points through luke and looked more dangerous... So he has the ability to guide a team around a park and create chances through means other than him taking on the line...
