The debate on rotational mechanics and linear weight transfer mechanics is as old as baseball itself. I'm not convinced it will ever be agreed upon, mainly because neither term really applies to my way of thinking.
> > > > > > Unfortunately the body is not constructed with a single pole in which to rotate upon, in fact, our legs, are like that of a tripod. They help keep us grounded and if one leg is straigter than the other we have hip or spine tilt. This straightning of the front leg is what generally turns a level cut into a slight upswing, or in some cases an extreme uppercut. The hip joints themselves do not turn, it is the torso, constructed from the base of the spine that creates the torque. However in an effort to add upper body torque, many hitters feel the strong need contribute excessive leg action (ie..hip thrust) to get the torso to turn. Normally it is young hitters that create this excessive leg action that never really feel the torso power. In other words they combine the torso turn with the leg thrust. This excessive leg action is what most hitting instructors have the hardest time seeing and teaching.
> > > > > > I have a real concern with anyone that preaches straight legs in the baseball swing, mainly because straight legs create angles and also lock hips, which contribute to bad balance. In any sport that I lock my legs I get beat. Lock the front leg early in a baseball swing..... and I'll get beat. Now I must say, great hitters do lock there front leg normally (not always), however, it comes with a price even for them, but the real issue is how they go about locking the front leg. Getting into that all too familiar "sit to hit position" is the art of a great athlete and generally a great hitter. In viewing Jacks video I see the kids just straightening the front leg, with never the notion of sitting to hit. But then I see the hitting instructor, getting a nice front knee bend, thereby, positioning the legs for all of this upper body torque. In golf they call it the "magic move." This magic move is a slight lateral slide while the upper body begins it unwinding (rotation). This to me is why the debate is never ending. Great atheletes/hitters can do both at the same time, but when either becomes excessive , then you have a issues in my opinion. This is why everyone looks different when they swing in my opinion.

> > > > > > In summary the front leg becomes the core element of my teaching. If I can get a kid to keep this leg in contact with the ground at the initiation of the swing, but with good flexion and stability and I give this kid the best opportunity to be succesful. If I see kids locking legs than he or she will have problems, until they understand how the front leg is supposed to lock, by rotating laterally with athletic legs.

> > If the rear shoulder drops then the front leg straightens. Many instructors view the back leg as the culprit for uppercutting, but I believe the rear shoulder should be trained to rotate level. One may choose to dip it, but understanding the risks and what one gives up should be considered. Training the rear shoulder to rotate level is very easy if you take the time. Here's the deal, train level and the upswing will be minimal at game time. The rear shoulder keeps the lead elbow down, which I believe controls the direction of the bat head and maintains the connection of the lead arm to the upper torso. In golf this translates to effortless power with the arms..........It's a beautiful thing in the baseball swing to be able to swing as hard as you want and know that if the arms are on plane. Kabooooooom!!!!! Thus the straightening of the front leg becomes that of rotational forces of the upperbody centrifical force. A straight leg is not required, just a firm leg. Money doesn't motivate me, being correct for those I teach does.

> I can now see why your hesitant to give details. Rear Shoulder level? lead elbow down? I have probably 100 clips or so of the best major league hitters and none of them rotate the rear shoulder level and none of them keep the lead elbow down. Maybe your instruction works in cricket?
