Who will play in the halves for NSW is the biggest talking point this afternoon.

It is no certainty that Nicho Hynes (halfback) and Jahrome Luai (five-eighth) will be selected for Game II at the MCG.

Parramatta's Mitchell Moses and Souths' Cody Walker have put their hands up for selection.

Both have played for the Blues before.

Parramatta interim coach Trent Barrett has backed Moses to be selected. Moses was not available for Game I because of injury.

"Mitch is three games back from his foot [injury]. I think from a State of Origin point of view, I think he's our best option,' Barrett said on Saturday night.
