I think you just nailed the biggest problem that NSW have. You cannot just copy QLD and have an ex former origin great be the coach and hope that results follow. Stuart has proven that when left to his own devices and with the players he hunted in club level that he is not a good coach. He only did alright when continuing someone else's' hard work.
I know that they want to keep consistent in the playmakers, but Pearce is still too hot and cold week to week for mind, and Carney needs to be well supported in the halves to be properly effective. Not sure there is a great combo with him. Personally I like Wallace / Soward, but as a QLD supporter I am more than happy to see Pearce and Carney play or the blues.
DeGois is also a player who has struggled with injuries of late, and I cannot see them selecting him incase the halves misfire and they need to be yanked to make way for the utility.
The biggest mistake NSW can make right now is to select Ennis. He does not deserve to play club footy, let alone anything higher, and his form the past year has been woeful. However as others have said, Stuart loves his thugs so I wont be overly surprised.
