"quickening up a lot at footstrike"
Yes this is the pause Im talking about. Its not a smooth transition. This quickening up you do. How do you do it? is it muscleing the arm? Muscling the trunk, abdominals/obliques? Or does it happen naturally at foot strike?
Playing infield does not help your pitching motion, but throwing football can. Forget about the quick and short stuff. They frequently talk in football about not to throw off your back foot. Does it feel similar when you throw a foot ball off you back vs front foot? It should be very different. Watch Payton Manning in the pocket because Im a Broncos fan . No.. but there is something you can learn from him.
