Regarding the amazement that LC has omitted both Redhage and Ballinger, here is my view of the situation.
I think there is little doubt the following players will, if available, make the squad:
Patrick Mills
Brad Newley, Joe Ingles
David Barlow
David Andersen
Andrew Bogut, Nathan Jawai
Brett Brown has shown, in all his squads thus far, a preference for selecting three PGs, with the remaining two likely to come from the following:
CJ Bruton, Adam Gibson, Matthew Dellavedova
CJ will certainly be one of those if he makes himself available.
This leaves three places left in a squad of twelve. The squad will contain at least one more genuine big which neither Redhage nor Ballinger are at international level. This player will likey be selected from the following:
Alecs Maric, Matthew Neilsen, Luke Nevill, AJ Ogilvy.
That leaves two spots on the squad to be split between whomsoever is remaining from the above four players and the likes of Mark Worthington, James Harvey, Aron Baynes and others. Then throw Redhage and Ballinger into the mix.
Personally, I think it would be a massive call to leave Neilsen out but Maric has shown great form in the Euroleague and Nevill, at 7'2", adds genuine size so it's likely that at least two players from that group of four make the squad, leaving the remaining to fight it out for one spot only.
Regardless of both players undeniable talents, I think it not only possible that Redhage and Ballinger both miss out, I think it likely.
