Dear Steve,
Im still a little confused on your
terminology/descriptions and whether Ive been clear in my descriptions.
My basic premise is that once shoulders start to rotate,
you cannot effectively create displacement between hips/shoulders. Again, its
Barrys statement of "as long as you MAKE SURE that you shoulders are closed,
your hips can open as much as they want. You see, this is what creates all of the torque,
like a stretched rubber band, ready to explode with much energy." That supports my
statement (or triggered my statements). I do not disagree that there is hip AND shoulder
rotation AT and AFTER foot plant. I am saying that the opportunity to generate this
displacement is gone and the benefits are lost if you dont achieve this displacement
before/at foot plant.
I did not want to stir the pot even more in my last posts
about Rivera, but my clip shows significant shoulder rotation prior to foot plant. This
indicates more activity due to the post/drive/stride and is more typical of pitchers who
are more erect and have higher release points (Schilling, Tom Gordon, etc).
My observations/studies seem to indicate that the amount
and type of hip rotation is dependent on pitchers arm path (release point). Shoulder
rotation should always around spinal column. The higher the release point, the more
inclined the spinal column which in turn effects the type of rotation. The hips go from a
more horizontal to an around and over path. Ryan was horizontal Rivera is around and over.
All this adds confusion to what you/me think we see and prevents rigid rules (you must do
this!!!) of instruction.
As far as power path of hips. My feelings are that once
you establish foot plant, there is little you can do to help the hips turn. Before
everyone goes into orbit, try this simple experiment. Take a stride so that you weight is
50/50 and hips are closed. Now have someone stand behind you theirs hands on both of your
hips trying to prevent you from turning your hips. It takes very little force to stop your
hips from turning no matter how hard you try to pull them around. So much for the hips
generating lots of force by pulling after plant.
As the Bear would say "Cheers"
