LeBron James turned away from his teammates gathered in the center circle and waved to the fans as if to say: "See you Sunday." Right where the U.S. men's Olympic basketball team always expected to be, in the gold medal game, against the opponent it figured to see again. "Anything less than this would have been unsatisfying for us," Carmelo Anthony said. "We believe that we could get here, and we're here now. We got one game left." Kevin Durant scored 19 points, James and Anthony added 18 apiece, and the U.S. turned on its slamming-and-shooting spectacle in the second half to overwhelm Argentina for the second time in five days, 109-83, in the semifinals Friday night.
