Motion Defensive Coverage?

[coachcbjii]

One of the new features mentions "Motion Defensive Coverage" - What does that mean?
In the custom play designer, I do not see a way to move defenders around - Like the ability to drop a safety down in the box.
So I am just wondering what this new feature does?

It was an update to the engine so that defenses will react to custom motion plays better.
