I feel that Jayson and Schmidt have that approach as well, and have variously said that they find that approach to break shots has become their preferred way.
The unique thing that both Jayson and John share is their total confidence with
deliberately setting up the most
acute imaginable, back-cut break ball angles on their break shots. More acute than any of the top high-runners.
There's a self-evidently instructive principle in becoming very comfortable with those alarmingly acute angles. Needless to say their make-miss percentage on them is off-the-charts positive..
Arnaldo ~ Mosconi himself routinely and daringly set up for his break ball exactly as JS & JS do in modern times. Few of Willie's competitors were as daring and flawlessly accurate with those uncommonly acute breaking angles. It just occurred to me that aspiring high-runners could have a leg up by going down to city hall and for $25 bucks get their name legally changed to a first and last combo that
conferred on them the initials JS.
