It's the Landry Shift
Landry Shift
An offensive line technique, the Landry shift features all linemen but the center moving from a three-point stance, standing briefly into a two point stance, and back down into a three-point stance. Often, this also meant motion by the running back behind the wall of standing blockers, making it more difficult to see the new alignment of the backs. Legendary Dallas Cowboys coach Tom Landry is credited with developing the shift.
