CaCO3Girl posted:Personally I think the legs, hips, trunk, head, glove arm, shoulder....etc are all secondary. Consistent elbow angle is the biggest factor. As for the OP, the average human wouldn't be able to detect the difference in the release point, that is what makes pitchers so amazing.
Throwing begins from the ground up. If you are throwing the ball properly the legs, hips, and trunk are always the primary considerations. When you get consistency with the lower half & the trunk then (and only then) can you get consistent with an arm slot and a release point. Then you can command where you throw the baseball. When proper momentum is created with the body (and it starts with the big muscles - legs, hips, etc.) the arm goes along for the ride. Focusing on "elbow angle" (I'm assuming you mean at delivery - but that is not a common term) and considering everything that leads up to it to be "secondary" is the ultimate definition of getting the cart in front of the horse.
