Leaving the court w/o authorization

[Hartsy]

I have seen a lot of discussion about calling the technical foul for "leaving the court without authorization" when a player runs below the baseline to avoid a screen.

What makes this any more a tech foul than someone jumping over the endline or sideline to save a ball from going out of bounds? In each scenario, the player "left the court without authorization". And don't try to use advantage/disadvantage. The player saving the ball may gain an advantage for his team, just as much as the player avoiding the screen may gain something for his team. No using the momemtum argument either. Going for the save is an intentional act, so there would be no momentum causing the player to leave the court if she did not choose to go after the ball.

Let's chew on this one a while. I think there are a lot of loopholes in this rule.
