Verticality

If we all use the common sense explanation of VERTICALITY it will help us all make the right call or no call.
​
The principle of verticality means that a player is entitled to his/her space that is occupied, plus all the vertical space above the 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 a defensive foul. The key to Verticality is REFEREE the DEFENSE he/she will make the call or no call for you.
