Why no mention of dropping or not dropping the elbow/shoulder during the stroke? I believe dropping the shoulder during the stroke is a significant cause of missed shots. What do you think?
Yes, I agree that poor fundamentals, which would include excessive movement of the shoulder or elbow during the stroke (before cue ball contact), would certainly be a cause of missed shots. However, this article was not on fundamentals but an intro to the wonderful world of 3 cushion, therefore there was no need to mention grip, stroke, etc. See my previous article on fundamentals for more info on those aspects.
