LeBron James crazy off-the-backboard dunk during warm-ups. VIDEO.

Wait for the 39-second mark. During warmups, LeBron James flipped the ball between his legs from the free throw line, the ball went off the backboard, and he caught it nicely for a self-alley-oop. Easy perfect score in the dunk contest. Plus, he got it in one try. In. One. Try. The NBA Slam Dunk Contest can be a superstar event again. If only the NBA can find a way to make the superstars join. Grabe si LeBron. Even during warmups, he's in video game mode. MH
