jump stop

[bonehead]

A legal jump stop or traveling?

When a dribbler pickes up the dribble and jumps to a stop and lands on both feet simultaneously, he can not pivot on either foot. He can only jump to shoot or pass.

When a dribbler pickes up the dribble and jumps to a stop on one foot followed by the other is it a jump stop or traveling? If a jump stop, can he pivot?

I have seen it called both ways. Some coaches agree some do not. Is one foot followed by the other just like a lay up?

Does the dribbler actually take a step after he picks up the dribble and then jumps to a stop?

Who can define the jump stop?
