It sounds a bit like there might be a principal of verticality question and I'm curious about two things: (1) how truly straight up & down the defender's arms were in each situation, and (2) what "straight" really means in these situations. I ask because my observation is that virtually no defender has arms/hands straight - perpendicular to the floor on these plays. The angle seems to be 15-20 degrees even for a defender who has not moved hands/arms down & back up as in BktBallRef's post but has actually held still. When I look in the mirror, I realize that my hands/arms are not perpendicular to the floor unless/until, as I raise them, I place some strain (minor but appreciable) on my shoulder joints. Is anyone able to give this any precision beyond you know it when you see it?
