Walt,
A lot of people will ask whether or not you analyzed up stream as well. QL, Psaos, Hip flexors, T spine, shoulders
Other people will also ask about the symmetry of your body.You may be using your one side more so then the other causing tightness. I think one person brought up the idea of having good external rotation on one side and bad external rotation on the otherside as a sign that your body is compensating.
I don’t think any banded exercise is going to really fix this type of issue. In my understanding this type of issue needs a physical therapist to watch you move and also use there hands on your body and then watch you move again. I imagine as soon as they fix you, you will need lots of coaching to catch yourself falling into the same bad habits.
