In both cases referred to both myths there is an exception with an airborne player: if the defender set up position while the ballhandler is in the air, a landing spot must be given to him. If the ballhandler lands with both feet and then proceeds to contact the defender, the offensive player is responsible for the contact and a forced turnover against him is charged, meanwhile a forced steal is registered in favor of the defender.
When we are defending a player without the ball, it is a "screening" situation, which may require time and distance. In the cases referred in this topic, we call this "guarding" situations which only require that a legal position must be set up, which could be less than a step off.
