I do agree that he looks very good. Lower body is right where it needs to be. All the things that i mentioned in that previous post are there. Upper body looks really good too. It appears the arm stays connected to the spine throughout the whole delivery. Doesn’t have elbow above shoulder, forearm flyout, crossing of acromial line, or elevation of distal humorous which is what they look for.
The one pick i have is the arm recoil. You need to ask him where he gets pain first off, and let him know that he should be totally honest. Pain/discomfort is where inefficiencies begin. If he does have pain in the back of the shoulder, then he needs pronation work in my opinion. You will get that at Wolforths if you plan on going sometime this summer. So first off, ask where he gets pain, and then we can go from there.
