To make $, don't get me wrong, she has done so much for this sport. But that just reinforces the wrong mechanics. I can hear dads & moms," that's not what Jennie teaches".
I have said this before. We went to her camp a couple of years ago and she and Doug (her Dad) really reinforced a hello elbow finish. If you watch her pitch she doesn't do that until the very end after the follow thru. She will take her hand and force it back up to the right shoulder area. It all happens so fast that some may not even realize that is what she is doing.
