I agree here... at best you could consider Sandow a central to right side player and Roberts a predominately left sided player but they are in no way play on the same side. Next year I would love to see Sandow play a lot more through the middle then he does at the Rabbits and shit right less (maybe in a 50-50 split rather then a 20-80 split). This way it could probably be Matuia right, Sandow centre-right, Roberts left and Hayne everywhere (but he heavily prefers the left anyway).
This is the main problem with Souths IMO, then they are a close game their attacking structure is all left because Inglis and Taylor are there but Sutton is very rocks and diamonds and often all is seen in the same set. They struggle to build pressure when the game is in the balance because Sandow is almost removed from the attack.
Its only when they are in non pressure situations (ahead or behind by a fair amount) both sides see the ball more evenly and that is when they flurish IMO.
