Nailed on that Matty Smith will have an outstanding game for Salford tonight in a good victory over Saints,,a couple of tries and assists,,hope not !!!!!!!!!!!!!

Because, essentially, they're more or less the same player, Smith being a slightly poorer version of Finch. Even with modern tactics you still need some kind of a combination of a mainly runner and a mainly passer/organiser in any successful halfback partnership. Put 2 passer/organisers in the halves and you're as predictable and 1 dimensional in the backs as we currently are with having 2 runners there (or, more accurately, 1 runner and 1 n/a...)

Here endeth the lesson...

Not sure that's as true anymore though with the increased presence of a FB as a third pivot. They can generally provide the "running" option so two organising/passing halfbacks could easily work, just make them split.

I understand your arguement but I don't neccessarily agree with it, as much depends on the other players in the team. What you do need is a creative player on the left and right side of your attack.

Does Wane organise his team that way though?

That wouldn't work with your plays, your attacks are based on long sweeping moves involving both halves. If you split them you'll make half your play book irrelevant.
