VIDEO: LeBron finishes off alley-oop with powerful slam

The Cleveland Cavaliers toyed with the Charlotte Hornets in the first half of Friday's game. Cleveland led by as many as 39 points and took a 75-40 lead into the break. 

Newcomer J.R. Smith found LeBron James for two of those points by throwing an alley-oop pass from halfcourt that was finished off with authority. 

James scored 19 points on 7-of-9 shooting from the field with six assists to pace the Cavaliers. Yes, he's back.
