It is not an illegal dribble until the ball is carried in the palm of the hand...something relatively impossible if the hand is facing down towards the floor.
Palm facing up...palm facing sideways....palm "pushing" forward....there MAY, repeat, MAY be a call.
I always tell coaches "I got no carry...ball was not at rest"
As Hawks Coach says, I say nothing to the fan.
High dribbles may be ugly, but they're not illegal.
