First of all I resent the comments made by Mr BS. Follow-through is VERY important because a player needs to finish the delivery without having the body jerk. It's a natural result of delivering the cue and accelerating THROUGH AND BEYOND the cueball. This coach believes in follow-through because as has been said you can't possible stop the cue once the cueball is hit because it's a matter of physics. I suppose you could stop the cue but it would sure cause a jerk in the body and result in deceleration in all cases.
