Left behind is a relative term but I would say 'yes', the US were left behind in International terms. 6 years without a major international title for a country of 300 million people and the enormous resources poured into the NBA and the college game is to me being left behind (I know - we should be left behind so badly!)
But a lot of the rhetoric surrounding the Redeem Team was about the project they undertook and the adoption of many 'international' initiatives, such as squads and camps and 3-year programs.
While the women's program silver in Brazil was a smaller bump, the US didn't give due respect to the way other countries were playing the game and the progress they had made.
Correct me if I'm wrong but three of the last four MVP's in the NBA were foreigners? Best female player in the world is an Aussie?
Again, a relative term, but perhaps 'left behind' should be replaced with 'marked time while the others caught up'.
As opposed to the women's program, the Boomers success is about beating every other nation (given the assumption that the US should be out of reach) so we must excel at the international game. That is the only way basketball will remain relevant on the local level.
Alternately, we resign ourselves to being a minor player in a parochial sporting landscape (our favourite sports are seemingly those in which we can excel with little or no competition from elsewhere - AFL, Rugby League, Netball - and with the increasing globalization of swimming, we seem to be losing interest in that!) because as an international sport we can't hope to con people into thinking they are seeing the best in the world because they will never reside here - we simply can't afford them.
Patty Mills is relevant because we see him taking it to the US at the Olympics. Nathan Jawai is relevant because we saw hi play in the NBL last year. If the league can create more of these players, the local league maintains its relevance.
So the next question is what constitutes 'excelling' and I think the answer to that lies with the marketing department - 7th in the World sounds pretty good to me, while top 30 in the world sound fantastic to football fans. Why was there so little hoopla about the Opals silver in Beijing - because expectations meant that basketball people were desperately hoping and cautiously optimistic that gold was possible and non-basketball people expected gold from the reigning world champions, so silver was a failure. If we can learn anything from football, it should be diminishing expectations by overstating the magnitude of the task, and then celebrating every minor victory!
