2-Guard Front (2 teammates above the Top of Key OUTSIDE BOTH LANE LINES = 2 SLOTS). Open Post Motion Offense means the ballside low post is empty. 1st pass across the top is a Guard-to-Guard Pass.
Would work for both, but primarily effective against a man. The post needs to make sure to seal in the gaps for it to be effective against a zone. And the screens to screen the zone, not the man. Hope that makes sense
