Is it a foul if a shooter jumps into my space?

Principle of Verticality

The principal of verticality means that a player is entitled to his/her space that is occupied, plus all vertical space above that player. Therefore if a defender has his/her arms straight above his/her head, and the offensive player with the ball jumps up and there is contact with the defender´s arms, it is not considered an defensive foul.

How is that an offensive foul if the defender is violating the offensive player's vertical space when contact is made? I think your definition is wrong.

You were completely correct Scott. I'm still in the process of cleaning up the site from the previous Guru, and for some reason that one slipped by me. Thanks for the catch, I have made appropriate changes.

The Most common place this is ignored is under the basket when an offensive player jumps up and back into a defensive player who is standing still inside his cylinder and a foul is called on the defense

The definition above states that the defenders arms are within his or her vertical space ( straight up). In order to make contact with the defenders arms, the offensive player would have to jump into the defenders vertical space and that is an offensive foul. This foul is rarely called in favor of the defensive player
