This brought 2 really neat things to my attention:
1. Knee Continuation. I had no idea, and all this really says to me is "get your footspeed and legs more involved and stop using your chest/shoulders to 'throw' the ball."
2. The "Swing plane" line he draws. Notice how the camera isn't directly behind the bowler, but rather looks directly down the target line. The swing plane is directly in line with the intended ball path, not the bowlers head necessarily (although both are true because they happen to be looking at where they're trying to throw the ball, obviously).
Great video. Thanks for sharing.
