Watching her throwing shoulder at release makes mine hurt every time.
I should be the last person nitpicking. But the brake foot/leg needs to be stronger and aid in keeping the upper half back and tall. You also have to want to have a strong/stacked posture because you need to activate the core to help keep it all together.
With that said, she’s likely had success at all levels with her mechanics. Many times pure athleticism and strength overcomes bad form.
