Would be more impressive if the camera didn't zoom in and lose the cube right before he solved it. Just sayin'.
Wait, did you just say that in order to be able to do the amazing tasks he performed together, he has to know how to do the amazing tasks individually first?? BRILLIANT!!
Uh, he has to solve it no matter how it lands in his hands (ambidextrous like), size up what to do in a split second, then execute turning the cube, without dropping the balls. This is by far and away the most impressive juggling act I've ever seen. And I see many amazing ones on Pearl Street Mall in Boulder during tourist season.
It's weird...everybody thinks what Lebron is doing is so impressive, but really all you have to do is learn how to shoot like him, dribble like him, pass the ball like him, see the court like him, play defense like him, and grow about half a foot, and you can easily be as good at basketball as Lebron. Right?
