traveling question

[Adam]

Describe the stop, first. As you wrote it, I'm picturing player in the air catching the ball (or stopping a dribble), jumping off one foot and landing on both simultaneously. If so, then this is a jump stop and it's a travel as soon as the player lifts one foot and puts it back down.
If the play is actually a player in the air catching the ball (or stopping a dribble) and landing immediately on both feet simultaneously, this is not technically a jump stop. Player may then choose a foot to be the pivot, just as if he'd caught the ball with both feet on the floor.
