"It is not JUST that the lead arm extended too much .
It is also the case that the hands dropped substantially ---note that the hands are almost down at the waist.
And thus the barrel angle is far too "steep" at that point in the clip.
Back scap not being used to pull the lead arm back and up into the shoulder line....thus lead arm never gets connected to the lead shoulder line of pull.
Meaning that in not really loading the shoulders well,this adversely effects the hands/lead arm/knob to effectively LINK with the LINE OF PULL of the arc of the shoulders rotating along the transverse plane.
When the arms /knob are pulled downwardly as in the above clip,you are MISALIGNING/MISDIRECTING the arms/knob/barrel .
In effect ,you are creating 2 different momentum paths of the trunk and arms/barrel.
Inherent to this is a degrading of bat speed, swing quickness ,and barrel accuracy.
Now,she DOES recover [compensate in a pretty effective manner] pretty well.
Two reasons why:
1] She does turn pretty well.
2] The back arm flexion angle from lag to contact articulates well ,i.e., it stays pretty close to the back side oblique region .
Now, from the standpoint of working with this hitter to try to improve the shoulder loading/lead arm alignment, I'm not sure if there would be time to try to improve her swing.
I think Mark said she is in college now -----and has been reasonably successful [at least that is what I think Mark had been told ].
One more point as regards flaws.
IF I was working with her,I would "play around " with her set-up ----more centered /forward centered ,and work at a better dead lift -like posterior chain loading.
In part to see if she could create a slightly different ---better ---manner of shifting /sitting .
[Her head appears to be not quite as centered as I think is optimal ,and the heel exchange is not as quick as I think it could be /should be].
