How do you reason that? Because Biraz was in the development squad?
So then you're saying that Sarkies and Musalik were next in line in 2006 in case of injuries.
Biraz went over there as part of the development squad didn't he? Not because he was the 4th best keeper in Oz.
and to answer your question: no.
Do you think that had Eugene, Langerak and Ryan all got injured Biraz would have started vs Chile?
