You people have it all wrong.
I've said it before, and I'll say it again. The reason why Team USA lost was because they haven't had enough time to play together as a cohesive unit. And because we haven't had a consistent system in place for an extended period of time like the international teams. (i.e. Coach K being the head coach).
Here is what happens. When you're a team that hasn't played together much, and you encounter a pressure situation, you revert back to your individual instincts. You don't have a proper game plan, you don't have the proper experience playing together to counter the pressure situations. As NBA basketball players, that instinct is to play isolation and try to break teams down, and to chuck up 3 pointers. You can't expect Team USA to be able to beat GOOD international national teams with only a month of practice. These teams have been together and played under the same system for YEARS. They know how to react under pressure situations as a team because of experience together, and enough practice under one coach and one system.
I'm proud of Team USA, and they got as far as I expected them to. This wasn't an upset. Greece is the European Champion, and as of right now, is the BETTER TEAM. All Team USA had going for them in this tournament was to high pressure other teams, and depend on their athleticism to beat their opponents. Which is what you do when you're not familiar with each other. The problem is, being more athletic and high pressuring other teams won't work when you run against a good enough team that can handle that pressure. And as you get further into the tournament, you will eventually run into the 3 or 4 teams that can handle that pressure. Greece being one of them.
Team USA is on the right track, by having a coach and a team together for a 3 year (or however long it is) committment. This way, they get to play together (or at least practice together) next summer, and then play in the following summer as well. They have established a national team pool, where they can continually evaluate players, and try to put together the best team at the right time.
But they need to take it a step further: they need to implement a FULL TIME coach. Not a part time coach like Coach K, who also coaches the Duke Blue Devils. It needs to be a full time coach, who can travel extensively and evaluate players in the league throughout the year, and also travel and evaluate opponents when they play as well.
We did a lot of right things in this tournament. The at ude was good, the team was better put together, the approach was improved. But we have to take the next step in order to beat the elite international teams. We have to play together more often.
I'd also like to say that Sabar has it right as well. Team USA played as well as they possibly could under the present conditions.
