Can a person who dribbles go out of bounds then back

[Brad]

You cannot go out of bounds while you are dribbling (i.e. step on the line while you are dribbling, but not touching the ball).

However, you can lose the ball (i.e. on an attempt to stop it from going OOB), step OOB, and come back inbounds to recover the ball.

The only requirement is that you are NOT touching OOB when you touch the ball. That is, you have to be touching inbounds (or have last touched inbounds if you are airborne).

There is no requirement to have two feet "established" back in bounds as some fans/coaches/players believe.
