I read it all.. I am referring to this quoteWILLIAMS: Now, if I swing slightly up, I hit it with the greatest impact. This swing incorporates the single most important thing—not shifting your weight but getting your butt moving, your hips working.
""Try to swing down. There's no hip movement at all there. "
You are not understanding my point, I'm not saying Williams did not incorporate the hips/core in his swing. I am talking about the portion of the discussion where he's referring to swinging down. Maybe you are just misinterpreting on purpose to cause confusion, IDK.
