Im not an expert on basket ball, but doesnt the same rule apply there?

you are not allowed to block balls from going in the hoop, once they are on the way down, but you CAN block a shooter

if you could goal tend in basket ball - place your tallest player by the backboard, and have him swat away every shot, basketball would be dead in a month

scores would drop to the single digits

good heavens - it would be almost as boring as hockey!
