Defense the focus for high-powered US basketball team, Kerr says

With a roster that boasts the NBA's all-time leading scorer, multiple title winners and the best shooter to lace up a pair of high tops, the points are sure to come for Team USA at the Paris Olympics, head coach Steve Kerr said on Friday.
