LeBron James played through back soreness, only to twist his ankle, and Anthony Davis had 30 points, 11 rebounds and three steals -- giving him a franchise record three straight 30-point, 10-rebound games -- as the Pelicans pulled away in the fourth quarter for a 105-95 victory.
"We suck," the Heat's Chris Bosh said. "We need to turn it around. There's no passion. There's nothing."
New Orleans got 14 points from Tyreke Evans, 12 from Al-Farouq Aminu and 11 from Luke Babbitt.
Mario Chalmers scored 19 points and Michael Beasley 16 for Miami, which trailed for all but 18 seconds of the second half and trailed by as much as 16 in the fourth quarter.
