A coach needs to see more on a video than swing mechanics, physical makeup etc..those are eye candy things as there is more than one way to hit a baseball or else we would all be doing it the same way..just as valuable is to see how an outfielder sees the ball off the bat and closes on a deep hit, whether he takes a proper angle to the ball, how a first baseman scoops a low throw, how quickly a third baseman fields and throws to the bag and if footwork, mechanics and accuracy are there, how well a catcher blocks and frames and how quickly he throws to the bag on a steal in a game... I fail to find the relevancy of exit velos off a tee or BP hits over the wall off 50 mph pitches in a showcase...it needs to be live game footage.
