The Call Most Often, or Most Egregiously, Missed

eroe, there is no requirement that a defender only jump 'within' his vertical plane'. Good defense would take a mighty hit were that the case. If the defender jumps first, s/he has the right to come down on any spot that was unoccupied at the moment of takeoff.

Jeff, this is just false. I don't know who taught you this principle, but it's wrong. The defender is not allowed to jump into the path of an airborne shooter, even if the defender jumped first.

If the defender jumps and is in the path of the airborne shooter, then the defender has to be "straight up", or within his vertical plane.

You can't just jump in someone's way, have a collision and say, "Well, I jumped first". You need to re-think the paragraph you wrote above.
