Who's calling 'palming' on this video

[Twinfan]

I would call it if I thought the action was a violation and, in this case presented by the OP, if the violation gained the attacker an advantage over the defender. As most guys have said, there seems to be a marginal case to be made that the move was a violation. However, I'm a bit suspicious that the angle of the video might not be giving us enough information. It looks possible to me that at the top of the dribble the attacker slightly repositioned his hand so that the ball was momentarily supported by his two bottom fingers. At that point, he seems to beat the defender with a sudden change of direction.

If I were on the floor and the attacker made the described hesitation move but was also able to manipulate the ball sideways by supporting the ball momentarily in order to beat the defender, I would call it. If he changed the ball's direction without supporting the weight of the ball, no call. For me, this one is "had to be there" and it will be all about the angle that you have on viewing the path of the ball.
