Bryce Harper Swing Analysis - Lower Body Power

what we can learn from inaccuracies in the Bryce Harper Swing article, Washington Post

when analysis of mechanics drivers or biomechanics is based on aesthetics it tends to focus on obvious external events, unfortunately the obvious external events very rarely coincide with important driving mechanism - the key elements of power and movement are things that we can't "see" and usually happen well before the visual event we are focused on

the good thing is that we can "measure" these key events using 3D motion capture and other tools including force plates and EMG
