Brett Hall and Phil Wheddon

As much as Greg Ryan is ridiculed around the world for his folly, it will be interesting to find out if the US goalkeeper coach Phil Wheddon was consulted by Greg Ryan about the keeper change.
It must be assumed that based on his daily training with Solo, Scurry and Barnhart, Wheddon is always asked for his input and insight.
Did Wheddon oppose the change and was overruled by Ryan or did he agree with it?
Also, what input on keeper selection and player substitutions did/does Brett Hall have?
Both assistant coaches' credibility and reputations could suffer in the aftermath of this fiasco.
