[just another ref]

Rehashing an old argument: Nothing in the definition of a dribble requires a second touch by the player in control. On the release, it is either a pass, a try, a fumble or a dribble. In the OP, the release seems intentional, so no fumble. I can't imagine calling it a try. A pass, by definition is "to another player." No other player is available here, so that leaves a dribble, which, by definition, occurs when the ball hits the floor. Violation.
