But that wasn't the case. Well not in the ODIs anyway.
The whole argument that players batting out of position (Eg. Flintoff batting so low) was part of a reason for the Super Series failures was incorrect, because for 2/3 games Flintoff was in very early on due to quick wickets.
The only example where a player playing out of position was detrimental to the World XI was Flintoff opening the bowling and Kallis coming in first change. Even then, Flintoff did a pretty good job.
Australia won because the World Xi were, for the most part, low on form and match practice, and Australia were much hungrier for the win considering the Ashes loss.
EDIT: After reading both of Hazza's posts, he basically said what I just said.
