In contrast, when defenders motion their hands/arms go downwards, making a "roof", as the shooter tries for goal we refs are challenged to detect contact--in fact I would assert that a foul is expected to be called. We refs are challenged to instantaneously and correctly differentiate between these two scenarios. Herein lies the challenge in officiating verticality.

Not to change the subjuect but are you familiar with Mid America Youth Basketball Tour and the assault on the referee in Whichita this past weekend?
