My first impression is that this is a girl that needs to find her foundation. I don't see anything in the motion that she has fully figured out yet. Each part seems to be a little off. What I mean by that is often you will see a young pitcher that has a good arm whip, but her drive is weak, or she drives nicely but has a stiff arm. Your DD is still in the formative stages so she is still figuring out how to throw underhand (I am guessing she is 9 or 10?).
I probably sound like a broken record, but at this stage I think the liberty or K drill positions are far more important than the full motion. I have a pretty simplistic view of pitching. There are really just three things you need to do. the first is teach a good arm circle and whip. The second is a drive, the third is synchronizing them. In that order also, although 2 and 3 go together.
So do you have any video of her doing drills without the drive? I think it is really difficult to get a good drive and upper\lower synch if the arm motion is still in the formative stages.
I agree. She just turned 12 (small for her age, as is her twin brother), and lacks coordnation. We're also overcoming a few HE clinics she attended before I found DFP. I can get video of her K drill tonight.
BTW, anyone know how to post a gif? Every time I try, it uploads as a jpeg...
