- at foot strike, your knee transitions from slightly inside of your ankle position to outside of the ankle position. This takes away from your ability to stabilize the front side and transfer maximum power to the pitch. You want that calf to be vertical. If you connect the dots of your ankle and knee, that should be a straight line.
- your weight after release is on the outside of your plant foot. Showing me that your front side is rotational rather than linear. Being linear with the front side allows for later hip rotation and more torque. More torque is more speed. If you can keep your weight balanced on that landing foot, you will have more energy directed forward where it can improve pitch velocity.
