No comment needed on its awesomeness.
Video is a flexible and powerful tool for the coach, its level of use is dictated by the coaches ability with the camera and confidence in it's application as part of the normal coaching process. The strength of video lies in it's ability to capture movement and speed rather than fixed shots. Many coaches are, needlessly, nervous because of the technology involved and it's application. The video should be built into normal coaching activity and viewed as additional to coaching activity.
