As the 76ers' lead grew, the fans got louder, the fourth quarter a bit more wild. It didn't get unpredictable. At least, not to anyone on the Spurs. Tim Duncan and Tony Parker have thrived in situations more uncomfortable than trailing on the road in the fourth against a sub-.500 team. Duncan and Parker pushed back hard-charging Philadelphia late in the game to lead San Antonio to its fifth straight win, 90-85 over the Philadelphia 76ers on Monday night.
