As I have been reading about rotational hitting, I see the word, "Extension" getting bashed a lot. I do teach extension, in fact it is one of my pet words, but I do not teach extension at contact. I teach it through contact. I want my hitters to stay through the zone, because most of my hittes spin off the ball with that front side as their first movement, causing the head of the bat to quickly leave the zone.
Words are so dangerous, because what a word means to me, might mean something different to someone else. I think often times as hitting coaches we over emphasize a word to keep another problem from happening in the swing. For example, I may say, "Stay tall in the back" to a hitter of mine who has a tendancy of dropping his back side way too much, causing the bat-head to drop drastically and resulting in the batter getting way under the ball.
I just think as hitting coaches words are dangerous and many of us teach most of the same things, but we use different words and lingo to do so.
