I agree that the efficient transfer of energy is a critical part of the rotational swing. I would argue that the best way for a hitter to do this is for them to be loose and not be constrained by overthinking the process.
Can't think your way through a good swing. Can't change a bad swing without thinking. It's a process.
Which is why I think Ted had it right. 1) The hips lead the hands, 2) Swing level to the ball, 3) Keep your hands inside the ball.
Certainly agree the pelvis leads. Swing level to the ball? Sort of. Never hack down through it but matching plane isn't going to happen moving between a high rise ball and a 12-6 nasty down break. Swing plane needs to match shoulder rotation plane as much as possible while the pitcher tries to screw you up. And of course, you want the ball to be going up slightly as it leaves the bat. To the extent possible, being closer to the pitch path with the swing plane is good but not the leading variable IMO. What does hands inside the ball mean to you? To me it means a late uncocking of the wrists commonly called whip. I've seen some other definitions though.
I believe once the heel drops and the hips trigger, instincts play a much bigger role in the swing than a lot of people care to admit.
No argument from me there.
