AT&T CENTER — When Tony Parker went down with a sprained ankle in the San Antonio Spurs’ win over the Sacramento Kings on Friday night, the second question asked was how are the Spurs going to keep scoring like this without Parker? The first question was obviously about how severe Parker’s ankle injury was. In beating the Detroit Pistons 114-75 on Sunday evening, Tim Duncan and the Spurs helped piece some of that puzzle together. Duncan put up a line of 16 points, 11 boards, six assists and five blocked shots in the win over Detroit. It was the first game in about a month or so that reminded everyone of how well Duncan was playing early in the season. Spurs head coach Gregg Popovich said as much after the game.
