I want to make sure I understand the idea of back arm bend/L idea correctly -- this research has found that the back elbow stays in an L at contact if the pitch is straightaway, but that on an inside pitch, there might be more arm extension? It seems like you could generate more force by extending based on the principle of having a longer "arm," but watching the slo-mo videos definitely shows hitters keeping their elbows in. Interesting!
