At this stage, there are only two players who HAVE to be there, and that's Jarryd Hayne and Anthony Watmough. The latter of the two has to be played on the left side of the field and his position cannot be compromised. On the other hand, Hayne can either play fullback where potentially he'd have the most impact or on the left wing where he's better suited. At this stage, I'd say fullback, but if Dugan continues to improve I'd have him over Hayne.
I'm still wondering who should be selected to play right centre or right wing. I know it may sound ludicrous but I do believe the positioning of players on certain sides of the field does have a major bearing on their performance and it's essential to pick a player on the side that they're most comfortable in. (Unless they're freakishly awesome)
If I was basing my decision on who is the best New South Wales raised right centre it'd be Jamie Lyon no questions asked. But, from the sounds of it, his heart doesn't seem to be in Origin. Another candidate is Jennings who's currently playing out on the right but so far that experiment has been a dissapointment. Which essentially leaves New South Wales with the likes of Champion, Scott, Idris, Reddy or Ayshford.
As for the right wing, there really isn't too many players who can play that position well except for Monaghan. The only other natural right NSWs wingers (worth considering) are Merritt, Gordon and Burt.
