This means that kinesiologists should be able to design the perfect grip and arm angles for a give pitch outcome. I love quantifying things!
If my theory is correct, you could create programs to teach people how to throw a certain pitch to a certain place. It could take the guesswork out of pitching. But yeah, it's probably theoretical at best. I'm not very practical
Well, no two bodies, two arms, two hands are exactly the same. You can't clone pitching motions.
And, if you believe the NPA/Tom House/most pitching coaches nowadays, you can't try to clone arm action from one pitcher to another without increased risk of injury.
However, any attempt to quantify something like this sure would be interesting. Think about how much goes into a pitch:
-arm action/arm path
-grip, including position of the ball in the hand and pressure applied to the ball
-the angle of the elbow and wrist
-the physical attributes of the pitcher including height and arm
-and plenty I'm not thinking of
I have no idea how you could begin to quantify the perfect way to throw a pitch.
You'd also have to decide how to define a perfect pitch. The definition would likely change from pitcher to pitcher depending on the rest of his pitch arsenal. For example, a Mariano Rivera cutter is so effective because halfway to the plate everything has still looked like a Mariano Rivera fastball -- arm slot, pitch position, etc. If Stephen Strasburg threw a Mariano Rivera cutter, his arm slot would be different and batters wouldn't be fooled.
