Team USA can be beaten, though it probably won't be. That seems to be the recent calculus, given that America had to come from behind to narrowly beat Lithuania, then looked quite beatable in its following game against Argentina.
Australia could pose a challenge should Team USA take them lightly. While Andrew Bogut is out with an injury, the Aussies boast deft ball-handlers like Patty Mills and Matthew Dellavedova, both Saint Mary's products. Together, they should test an American defense that has struggled in these Olympics.
Offensively, the U.S. of course has a high-powered attack, orchestrated by Chris Paul and LeBron James. The two combined for 12 assists in the last game against Argentina, and both are feeding a hot-shooting Kevin Durant.
Whatever the opposition, America possesses the ability to outscore it.
