Legal guarding position

[Hawks Coach]

Mark
The lead in makes no reference to defense, that is clearly true. But it is only a lead-in to a set of conditions that must be met. The very first condition that must be met to even have a right to this principle of verticality is that you must have legal guarding position. that is the construct of the rule you cite.

So until you can show me where an offensive player can obtain legal guarding position, I am not inclined to believe that verticality applies to the offense. Verticality by it's nature belongs to the defense, when contact occurs and the defense has maintained verticality, the responsibility is on the offense. When the defense either has not achieved legal guarding position (therefore having no right to verticality) or leaves the vertical plane, then the responsibilty of the defense.

That is, and always has been, the way this rule is written and intended to be enforced.
