[Carl Cramer]

A beginner question:

A1 loses control of his dribble ("interrupted dribble"} and crashes into B1 in an attempt to recover control of ball.

Or A1 "fumbles" a pass from a teammate and crashes into B1 in an attempt to recover control of ball.

Is the call the same in both cases? Is there any practical difference between a fumbled ball and an interrupted dribble in this scenario? In any scenario?

Thanks!
