I'm not convinced Kelly is a FG halfback. But why bother with Sandow unless we want to make the attack revolve around him?
We're far better off revolving around Hayne/ Norman through the spine, so play Kelly at halfback and instruct him to give early ball to Hayne on the loop or Hoppa in space.
If we don't play Sandow, there's less chance of him being exposed defensively, and more chance that he'll get the message and go elsewhere. If he's on $450k, and we pay someone else $350k to take him off our hands, then that's still $100k we're better off towards a player who can contribute in in both aspects of the game in FG.
Pou just likes Sandow because he only thinks in terms of attack....
