Lakers aim to use newfound defensive responsibility against Spurs

After tightening up on the defensive end in recent games, the Los Angeles Lakers will try to clamp down on the visiting San Antonio Spurs on Wednesday night at Staples Center. The Lakers (14-9) are allowing an average of 111 points per game, but they've given up fewer in seven of the past eight games while going 6-2. "Defensively we've been in tune," Lakers forward LeBron James told reporters after practice Tuesday.
