David, not getting into the whole thing just because I am on my phone...when I get home tonight I can include more.
Shift is weight shift. It is not the same as separation (hands back hip forward). So if you look at the gifs on page 3...the hitter in the shorts (Macia) has shifted most of his weight to his front foot, then he swings. That is SHIFT THEN SWING. Kemp, Cabreara, Posey, are shifting their weight with their swing, as they swing their weight comes forward. That is SHIFT AND SWING.
and I think I get that a little even though your hip is going forward that does not mean you are shifting your weight forward. I think it is really obvious and easy in the one gif (Macia) because he has shifted so far forward, I'm just wondering if this could be a matter of degrees in other swings where it is not so obvious.
To help me better understand would it be correct to state that most high level swings NEVER shift as much of their weight as far forward as the Macias gif? or is it just your contention that it happens later in the swing?
