I'm not really sure what you meant to say by this, but your post seems to suggest that the French National Team is heads and shoulders above the Australian National team, and that Mills having a large role for the Australian NT is your primary reason for this. You're completely wrong, if that's the case.
According to the official FIBA World rankings, France and Australia are ranked 8th and 9th respectively. And who's the reason for Australia ranking one spot behind France? Patty Mills! Australia's ranking is even more impressive when you consider the fact that their biggest star, Andrew Bogut, hasn't played on the team in years, and that the French NT boasts much more talented, proven NBA players such as Parker, Noah, Diaw and Batum.
