I most certainly do not go up the back the ball. My hand has a mind of its own and tend to turn itself too soon too early. For months I've been trying to get my thumb out of the ball sooner and stay behind the ball but have no luck.
Are you actually the guy on those videos with a big Morich banner hanging on the background? I love your the way you throw the ball. Is there a simple fix to a late thumb release?
