Square the face with body rotation, not hand roll
Rather than actively rotating the clubface through impact, the coach lets body rotation return the face to where it started, so the clubhead is at the same angle at impact as it was at address. He describes this as producing much less clubhead rotation, more consistency, a more predictable start direction, and less reliance on timing something in a millisecond.
