jemaz, I don't think that we do agree, but that is ok. Most of the good ones have either been taught well or have watched the good hitters and copied their moves. Good hitters talk about hitting all the time and so do good coaches.
I don't think that hitters sit around and talk about angles either. They do talk about the swing, and they spend a lot of time watching tape of their swings, and it is to learn and improve. They also spend a lot of time hitting balls in practice.
I have said this before, and I will say it again. If you want to improve as a hitter and you don't use video, you are shortchanging yourself and will not be as good as you can be. If a coach does not use it, he is either stupid or lazy and should be let go.
