I find the angle of the video deceptive. When I look at it closely he appears to be lined up at a 45 angle to home plate so it looks like he is balking.Lead hip is pointed toward 1stb.
I think his knee should be closed a lot more at full lift to allow more power to be generated. I also felt he commited everything down the line. ie weight forward too soon rather than holding a balance position a little longer. Arm dosen't have any force behind it.
