Jones would've been more deserving than McCalman...
But I think Sam Carter is the real unlucky one... excellent form all year...
McCalman is the incumbent.
There are very few decent 8s.
And of those props you listed, Slipper, Alexander and Kepu are loosehead props who can play tighthead.
They are not tighthead props.
Id suggest that Saia Fa'ainga is the luckiest player picked. Hanson from QLD is better than him, and Nathan Charles is a tight playing hooker who we need, who IMO is the 3rd best hooker in the country.
Id rate Fa'ainga as maybe the 6th best.
Edit: And Elsom was possibly the best blindside in the world around 2005/6.
It was when he went to Ireland that he really went to pieces.
Id suggest he is one of the best blindsides the Wallabies have had in the pro era.
