And this one
And when you say one doesn't leverage a fused core I agree with you. The hitters above are leveraging a fused core that is resisting. Their rear legs are turning their fused, resisting core forward. Their hands/forearms are turning the barrel rearward to go forward.
The core is not 'fused', it is active ... it is a major engine in the swing.
Neither is the rear arm yanked backwards .... or late lead arm pronation into impact.
