Looking at the new Homer Bailey. “Notice at the start of both clips within the first few frames, the 2008 Bailey is sorta hovering. There is very little up or down movement in the leg at the time . Contrast that with the 2009 Bailey…the knee is still on its way up and hasn’t even reached its maximum height. Yet, the clips are synchronized to release. The 2009 Bailey catches up with the 2008 Bailey because its body is moving faster.” [Baseball Intellect]
