Defending champion United States' lineup of NBA stars faces European champion Spain in Friday's Olympic semi-finals, a rematch of the past two gold-medal games that figures to produce another classic. The Americans have won 23 consecutive Olympic contests with a 10-year overall win streak of 74 games, but were tested in Beijing and London finals by a Spanish side featuring two-time NBA champion Pau Gasol. "We have ultimate respect for Spain," US coach Mike Krzyzewski said.
