Does this result in increased elbow flexion or no in your view. Speaking of a middle middle pitch here that doesn't fool the hitter to avoid variables for the moment.
We are all about keeping the elbow flexed and feel we can adjust to anything! When the lead arm elbow straightens our ability to adjust is compromised. We are very focused on the lead elbow making what we term a good first move. In my opinion we think the lead elbow is too high in most swings and it starts in the stance. Try it yourself...hold the hitters wrist ( lead elbow) with the elbow high and ask the hitter to move the elbow forward and they will not have much ability to pull forward. Now try it with the elbow a little lower and YOU will feel the power of the hitter moving the elbow elbow forward and up like it is going up a ramp verses a chicken wing going up or starting higher in my opinion. See it, feel it and fix it!
