All of that changed Saturday, when Team USA lost its first game since 2006 to Australia.
"The Aussies gave us a great lesson as far as where we have to be and how we have to play in this kind of competition," US head coach Gregg Popovich said after the game.
The loss comes two days after the US beat Australia 102-86 on Thursday.
The last time Team USA lost was during the 2006 semifinals of the FIBA World Championship.
The US' final exhibition is Monday against Canada in Sydney before heading to the World Cup in China.
There the two-time defending World Cup champion will face the Czech Republic on September 1.
