When does travel occur?

Look, my point is simple, but let me start by stating I agree with Nevada that the rules support is there if you want to call this violation prior to A1 retouching the ball. Whether the drop is a dribble or not is entirely up to the official's judgment.

That said, I will never call this before A1 retouches it. Players are smart, and this is one rule they tend to know. If it's really a dribble, he'll show you by continuing the dribble. If it's a pass, he'll show you by purposefully avoiding the ball; likely boxing out his opponent at the same time to give a teammate time to get to the pass.

Let me change the play slightly.

A1 goes airborne for a shot, realizing it's about to get eaten by a young Dikembe, he throws the ball towards and empty corner of the court. He then proceeds to follow it, where for a few seconds, he's the only player in reach of the ball. You calling the violation if he doesn't touch it?
