Basic Rule
"The basic concept of traveling is based on the “pivot foot.” Once a player receives the ball or picks up his dribble, he is allowed to move one foot, while the other foot has to remain on the floor as a pivot foot. This foot is allowed to rotate, as long as the ball of the foot remains on the floor at all times. A travel occurs when the player lifts the pivot foot and then returns it to the floor before releasing the ball on a pass or a shot. For instance, if a player receives a pass and jumps with both feet to attempt a shot and returns to floor without shooting, it is considered a travel."
Found this explanation above of travel. Seems like what I see is player lifts pivot foot and then dribbles before returning the pivot foot to the ground is being called travel. That is not covered above as only talks about "releasing the ball on a pass or a shot". Additionally found the following:
"If the player picks up this pivot foot prior to releasing the basketball for a dribble, he has committed a traveling violation."
So if both statements above are correct it makes a difference as between what you do next when you lift your pivot foot:
1. If you next pass or shoot you can lift your pivot foot 1st as long as you finish your pass/shot before you return your pivot foot to ground.
2. If you next dribble you must RELEASE the basketball BEFORE you lift your pivot foot.
My mistaken understanding (if above quotes are correct) is that I assumed lifting the pivot foot rule was the same for next moves being shoot-pass-or dribble, where seems like for dribbling is much more restrictive. Think I yelled at a few refs incorrectly if above distinction is true as relates to traveling calls being correct when player STARTS to dribble and LIFTS pivot foot BEFORE releasing the ball.
