I agree with the comment that if creativity is what you want then move hayne to fullback, while Stewart was good all series he has lost a lot of pace and his kick returns were docile which are meant to be his strengths.
Pearce was average but so was Thurston and Cronk (esp cronk) for majority of the series, we did only loss by one point and probably should have won the first game considering we were winning possession and meters.
It would be hasty to move away from Pearce to go with an untested halfback who has 25 games and Reynolds has shown nothing more then a good long kicking game, he has the luxury of playing with Sutton, Luke and Inglis to create points.
Farah and Carney have to be picked and the halfback position is between Walace and Pearce in my opinion because they are the only two with enough experience (and I don't rate Pearce at all).
If NSW are worried about creativity then Hayne at fullback with Morris and Uate on the wings, J.Morris and Jennings in the centres and there is a backline for the next 5 years locked in.
