Anthony Davis was merciless against his former team and LeBron James played a pivotal supporting role as the Los Angeles Lakers sank the New Orleans Pelicans. In a stellar show at the Staples Center, Davis plundered 46 points and 13 rebounds in a 123-113 win for the Lakers, who tightened their hold on first place in the Western Conference. James registered 17 points and 15 assists, with Davis' performance one of his strongest since his trade from New Orleans last July.
