When you see these angles it does show that the shoulder strikes the head before the head clash, but it also vindicates Cane even more, especially the view at full speed. Some people might think All Blacks are superhuman, but there is no way that any human could have reacted to Henshaw's pirouette in time. The best he could do was turn his face away to minimise the severity of the head clash, and that is a reflex action, not a wilful action. Even top gun fighter pilots only have reaction times measured in fifths of a second. You would need a reaction time measure in a few milliseconds for Cane to have adjusted his position to put the shoulder in like that. It is physiologically impossible for Cane to have avoided this. Its a pure accident.
