I thought that was the emphasis also. It could be that CoachYoYo keyed off of the comment at the 50-sec mark … “always leading with the knob goes to that ball”.
Yes I did key on that statement. She also states "so my knob and my elbow go down and inside the ball" which to me seems like a bad queue. Additionally, some of her subsequent swings show her elbow going up and not down.
