VIDEO: LeBron throws down big dunk, booed by Heat fans

Sounds like powering the team to a pair of titles in four years wasn't enough for Heat fans to forgive LeBron James for leaving Miami. 

Playing in his second game in South Beach since departing for the Cleveland Cavaliers in the offseason, James was booed during intros and throughout the game. He heard a lot of noise after throwing down a powerful one-handed slam in the fourth. 

James' Cavaliers fell to the Heat, 106-92, and were thoroughly outplayed for much of the night. Cleveland has lost both games its played in Miami this season, also dropping a 10-point contest on Christmas Day. 

A 16-point fourth quarter salvaged James' stat line, but he was quiet for most of the battle, finishing with 26.
