Rules Question!! Please help

[Adam]

It'll happen less often than a legal shot block after the ball hits the glass.
My opinion (I know, it's just that) is that the player is in control while dribbling. If he realizes, after stepping out of bounds, that the he needs to relinquish control, it's too late. And yes, I think you can tell by his actions whether the dribble became interrupted before or after he stepped OOB.
