My comments that follow are NOT intended to be "mean". Nor is my intent that of demeaning the player or coach involved. The reason I am commenting is because this swing is very representative of MANY swings I have seen over many yrs.
In other words this swing represents in a generic way, so to speak, a number of typical flaws that I have seen many times.
To set forth a bit of context as to what follows, I'll start with my simplest definition of a high level swing: Good hitters do 2 things really well; they know how to create very good bat/body alignment [from initiation to contact];and they know how to rotate really well.
To cite a good ex. of the former [alignment] here's a clip of Griffey:
englishbeyhitting.com/videoclips/gri…
These are [obviously] 2 pretty different pitch locations. Some postural dynamics to note: 1] Note the pretty centered position of the head to naval at foot plant [side view look];2] Note the relatively "squared away" shoulder line [very little actual inward turn of the shoulders]
3] Note the alignment of the upper lead arm being ABOVE the letters [through the entire unload] in both locations.
4]Note the translation of the knob at contact: In both swings the knob at contact has NOT traveled much if any beyond the lead knee.
5] Note that Ken begins to rotate the hips...AS the lead heel drops.
6]Note at contact his alignment of the barrel and the lead arm forearm----they form a straight line [what I refer to as "co-linear" alignment of the bat/forearm].
7] Note as to how "tight"[close] the upper lead arm is to the lead pectoralis from initiation to contact.
Furthermore I should add that ALL of the above parameters are VERY consistent with a typical good swing from a good MLB hitter.
Now comparatively, does the above hitter conform to ANY of these parameters? The answer is no.
In terms of being "centered" her head [at foot plant] is more over the BACK hip joint. As regards the shoulder line she has counter-rotated the shoulders a substantial amount.
A flaw that MANY are guilty of when hitting off a tee.[As I have stated MANY times...."the body posture will follow the gaze"].
As regards the upper lead arm, it starts the swing far too flexed [close to 90 degrees] and far too LOW [under the letters].
And as the swing progresses into lag the knob travel further downwardly [gets close being aligned with the navel].
This kind of alignment effects [of course] the contact point in that it will inevitably "push" the contact point BEYOND the lead knee.
It also very much impedes optimal uncocking ,i,e., the lead forearm and barrel do NOT align at contact.
Here's a good look at how this contact alignment should happen:

Lastly, she is NOT rotating the hips [as does Kenny] INTO foot plant.
Again, I want to emphasize that I only used this clip because it DOES [for me] serve as a kind of generic ex. of the kinds of typical flaws I see in many non-elite hitters.
I would only add that the apparent stated goal of "staying inside" is really the wrong goal. Rather the goal should be that creating much better bat/body alignment [from set-up, to initiation, to contact.

1]On a personal note. In the last few hrs. I spent quite a bit of time in a back and forth with an individual. I ALWAYS try to make these kinds of exchanges NOT PERSONAL. I have made it a personal goal to ALWAYS try to make it about the information.
2]And I always try to persuade via logic, rationality, objective research, etc. In the case with this individual it devolved into --on his part--- a number of ad hominem posts. I responded with very calm responses [don't get into the mud --stay above it].
3]And for me this is, at this stage of my life [I've been around--I've seen and heard alot], I did not get much offended. I simply countered his retorts with reason and logic.

..."pushing" the bat. Could you explain this to me".. Yes I think I can. I'll start with this common --but erroneous-- notion:
....." Since our hands, only at the turn of the barrel are even in a position to theoretically "push"....."
The hands cannot and thus do not contribute to or cause "pushing." The hands have one function and one function only: They serve to GRIP the bat. Period.
Now some may reply/argue that the hands help to "uncock" the bat ,i.e., the bat moving from lag to getting "out and around" [my phrase] and into contact. That is incorrect.

Paul prompted me to take another look at Kelly [I HAVE looked at him before this].And i wanted to make a few comments.
1]"Nothing special about his windup". I recently stated along the lines that...."loading is only as effective as it helps to UNLOAD." Paul, similarly, is hinting at the fact that is NOT primarily about loading. More fundamentally, it is about how one unloads.
2]Yes, of course, this DOES relate to loading. But I think the fundamental point is: One cannot NECESSSARILY conclude as to how one is going to unload....

These 2 clips are very good [but pretty subtle] examples of what I refer to as the relatively subtle difference between "squatting" vs. "sitting". Let me try to explain this subtle difference. And it CAN POTENTIALLY effect the swing [unload].
1] Note the basic initial set-up difference. On the left he is creating greater knee flexion/trunk tilt; on the right he starts with less knee flexion and less trunk tilt.
2] But from there as he starts to move [stride], on the left the first action is more knee flexion[subtle] --what I refer to as "squating"; as opposed to "pushing the hips back" via HIP FLEXION seen in the right clip.

Probably close to 20 yrs. ago is when I first ran across the concept of the "serape effect." This preceded finding Tom Myers's "Anatomy Trains", and along the same time I found Mel Siff's "PNF" exercise programs, and preceded finding "biotensegrity models."
ALL of which I find related in the sense that they all helped me to better understand how to think about, as I sometimes simply phrase it, "how the body works" in the specific context of throwing/swinging.
Here's a link I cited and talked about quite a few yrs. back about the serape effect:

I've talked about this before. I think the best physiological/biomechanical explanation is that the back leg action [post contact] is a REACTION to the upper trunk's [arms/bat included] angular momentum.
Said another way: It is a function of the distal component [the back leg] attempt to create greater gyroscopic stability, ie., as the as the trunk leans forward and as the arms/bat go "out and around" to get to the low/outside contact point, the back leg tries...
....to "offset" that action by essentially reacting in the opposite direction.
