LeBron James returned to Miami for the first time as a Los Angeles Laker Sunday, dropping 51 points on his former team in a 113-97 NBA victory over the Heat. James, who led the Heat to four NBA Finals appearances and two titles before returning to his hometown club Cleveland, made it look easy from the opening tipoff, scoring 19 points in the first quarter on the way to a season high. The Lakers never trailed, leading by as many as 21 points.
