In the first clip he is stretching the core and not rotating, nor is he turning the shoulders. You can't look at this clip and say the stride doesn't add power.
Also, Rdbass, is this what you mean that the shoulder don't rotate or power the swing?
In the second clip it looks like rotation is powering the swing, and I can see why someone might think the swing is rotational.
