The selection chaos you refer to is more of a case that players like Davis, Millen and Kenyon are out of the team because they were crap signings and because of performances when they were picked.
Pretty damning indictment of our off-field staff if the three experienced signings from the summer are not being picked within 6 months of arriving!
It doesn’t explain the disappearance & reappearance of players like Wood & Perry though.
