I'd like to hear some opinions on what proper footwork looks like. A review of the Model Pitchers shows that most elite pitchers swing their drive foot directly behind their stride foot either into a figure 4 or close to it ( Osterman, Finch, Hall, Lawrie etc.) while some draw a (mostly) straight line into their stride foot (Abbot, Fincher, Fowler). Some have their foot pointing straight down with toes dragging smoothly and some contort their right foot into positions that look as if their ankles will snap. Is this all a matter or style or is there such thing as sound drive foot mechanics?
