LeBron James may have some people getting a little salty at him for this one. After talking up a big game last year about how he would participate in the 2010 NBA Slam Dunk Contest LeBron James has now backed out of the event less then a month before hand, forcing the NBA to fill his slot. No real reason has been announced as to why LeBron will not be participating this year but needless to say there’s sure to be a lot of disappointed fans. We’ve been dying to see LeBron in the Slam Dunk Contest and he sort of ensured us all last year that he’d enter the event for 2010, and the NBA even had him listed as a participant, but now that has all changed. Forcing to fill LeBron’s spot the NBA will hold a dunk-off between Eric Gordon of the Clippers and DeMar DeRozan of the Toronto Raptors during halftime of the NBA Rookie Game. Whoever wins the dunk-off will join Nate Robinson, Gerald Wallace and Shannon Brown in the 2010 NBA Slam Dunk Contest.
