Thanks for your replies JD and the highly entertaining vids. No further need to preach to the choir here. I will only add that I suspect you may not be fully aware of the most recent drag movement headed your way.
I’m not saying looking at draglines is an entirely useless endeavor. Why not strive for a greater understanding of all aspects of a throw? However before we start adjusting a young child’s delivery in accordance with those draglines wouldn’t we want to be certain what it is we looking for and it’s significance? This is something that is far from being established IMO.
As for focusing on young kids draglines as soon as they step on the mound….
How do you know your not working with the next Curt Schilling, Dennis Eckersly, Jim Palmer, Rollie Fingers or Cliff Lee if he doesn’t drag….and if he does, are we absolutely certain that the drag line finishing on the rubber to plate center line is what we want to be doing? There is still some uncertainty about this, especially given the many examples like Maddux and other successful pros whose draglines don’t finish center. It all seems a little premature to be doing this with very young throwers…forcing something, that doesn’t yet need force.
Appreciate your reply. Certainly not trying to “shame” anyone. My sincerest apologies if you feel that way. Again it’s about the drag idea not individuals. If you and other “elders” feel this is an impossible distinction to make I will immediately delete this and all my posts. No problem.
The intent is to offer an opinion, which might save some people a whole lot of time and possibly frustration, all while having a little fun along the way. No denying the truth will sometimes have a little sting to it, and humor doesn’t always work. I suppose this is why it’s so much easier for the majority of us to just look the other way most of the time, and probably why I rarely post on open public forums.
If you really want to plumb the subject, show us the studies and data that led to the conclusion drag lines ending on the centerline lead to greater mechanical efficency. I’m not talking about what people may have said in books about the data, but rather copies of the actual data and conclusions drawn. Find us the studies and lets have a look. If it’s quality information there is a good chance it’s published somewhere. I don’t have a degree in biomechanics but have a related degree, and did spend the night at a well-known biomechanics lab last summer….
I’m currently reading through the following timeline with some interest. not done yet but doesn't really look like what I’m after. Get back with you when I'm done.
There are two aspects to drag being investigated. First is the type of drag itself, the second, how one adjusts their position on the rubber based upon when the back foot leaves the ground.
It has already been established elsewhere that the three groups of pitchers who:
1) don’t drag at all
2) have short or partial drag lines
3) have a lift off/ tap down action with their back foot
Constitute a large number of professional pitchers, possibly a majority. Due to the fact they leave little or no marks on the mound they create some obvious problems for those in search of a nice clean line in the dirt… so come prepared.
The second aspect of drag concerns ones adjustment on the rubber, if and when he does drag of course.
The key word here is obviously “efficiency”. In this case being defined as the hips and shoulders “squaring up” at the moment the back foot leaves the ground. Is this what we can consistently observe among elite level throwers and is this really a good definition of what constitutes “efficiency”?
