Stack & Tilt: My Follow Through

Here, the result of casting (releasing the club in the downswing) and not rotating my body enough toward the target clearly generates a poor follow through. Notice how Ernie Els (left frame) has rotated his body and released his right arm more fully toward the target.

This a point in the S&T instruction that I never really understood. Plummer and Bennet talk about extending the arms but not shaking hands with the target as Ernie Else is doing. Ernie is fully releasing the right hand directly toward the target. I'm not sure what the S&T instruction is driving at. The result for me was probably not what S&T instruction intended.
