Carney and Marshall are not even half as good at organising the side and plays as Robson is.
That is a clear and obvious fact.
Everyone has seen the improvement in the Sharks structure and attack since Robson returned.
Sharks with Robson this year - 3 games for 59 points
Sharks without Robson this year - 4 games for 28 points
Until you find a better or equal halfback to Robson, there's no way in the world should it even be considered that he is moved to hooker, or a part time role.
The sharks attack improved, because there are now two adequate points of attack. Thats what takes the pressure off.
Similar to how benji struggled with that shit krrnt, moltzen, Carney struggles with the even shitter chhunt in holdsworth.
Your statement could equally read
Sharks with two competent first grade halves this year - 3 games for 59 points
Sharks with one competent first grade half this year - 4 games for 28 points.
Benji has a massive boot, which would take the pressure off carney immeasurably.
Look, it's not the ideal combination based on the accepted norm of one defensive half, one flair half, but why buy a Ferrari if you're only gonna drive it to woollies. Marshall would be wasted at centre ...particularly in our setup.
