BARCELONA, Spain — It was the narrowest winning margin yet for the US basketball team in the run-up to defending its Olympic title, but coach Mike Krzyzewski said the 86-80 victory over Argentina provided a valuable lesson for his squad. “We learned a lot," he said, pointing to the way the traveling rule is called by international referees, the proud way Argentina battled back and the atmosphere of playing in Barcelona, where the Dream Team roared to gold in 1992. Twice the Americans exploded to 20-point leads only to see Argentina, bronze medalist in Beijing and Olympic champion in 2004, fight back. — Reuters
