				 Good point about body movement... 
 
			
			Wonderful observation regarding upper and lower body movements.  It makes sense when you see a defender moving away from the blocker to make the play and suddenly you see his upper or lower body moving faster/slower than the rest of him.  It helps me move from the scanning mode to the focus mode of my observation.  Once I move my eyes to the area of potential holding I can detect whats going on.
 Its all part of the "scan, focus, and react" method of calling fouls that I follow after reading my initial keys at the snap.
