LeBron James keeps holding off Father Time. Even at the age of 40, he can still do extraordinary things on the basketball court. He showed that recently with his crazy left-handed dunk against the Mavericks. It's a move that not everyone in the NBA is able to make.

James' Lakers teammate Rui Hachimura missed a corner 3, and Lakers guard Max Christie grabbed the rebound near the baseline. Christie turned toward midcourt and found James streaking near the 3-point line at the top of the key. He hit James with an in-rhythm pass, and James did the rest.
