NO ONE....NOT ONE....of the 2 hippers and 2 leggers.....can create a match of each of these swings.

The OBVIOUS proof is the lower right. That simply can not be accomplished any other way. YET.....he can execute the other swings also.

Same high level mechanics allow each of those swings.

When they stop guessing....pick up a bat....and swing to duplicate....and pursue truth instead of theory....the knowledge base will advance.

It's no one's fault but their own that they can't create a video match. And the fact that they don't post video is proof positive that they can't.
