>>> Again, a great discussion. I think we have disagreed about this before. But I still contend that there is very good bat speed at extension. In fact, I think maximum batspeed is at extension as Paul Nyman states. The problem comes from the fact that it is very difficult to get extension against top pitching. Griffey, McGwire, ARod often do, to name a few. It creates a long swing that isn't useful (it's fast but takes to long to get the barrel to the ball). Therefore, some batspeed is sacrificed for bat quickness by most all mlb players.

I have a clip of Arod, completely broken down, clearly disconnected and extending, reaching for an outside pitch and he hits the ball 390 feet. Where did that batspeed come from? It had to come from the whip effect. <<<

I thought you had “The Final Arc ll.” In the video/dvd we show 2 test that prove the whip effect is nonexistent with a ridged object like a bat. Go to “Bat Speed Research” and read ‘Test the “Crack of the Whip” Theory’. Believe me Teacherman, the theory is a fallacy when applied the baseball swing.

With all due respect neither of them illustrate a baseball swing, linear or rotational. If my wrist would swivel like your steering wheel knob then I'd give it some consideration. But they don't.

I don't have the ability to post the clip but you've seen the swing hundreds of times in baseball. The hitter is completely fooled by a change up or curve ball on the outside of the plate, low and away. The hitter has committed to a different location so he "throws" his hands to the ball and reaches full extension at contact. He has completely disconnected, the body went left and the hands went right, and still hits the ball 390 feet. There is no top hand torque in that swing, there is no bottom hand torque in that swing, there is no circular hand path in that swing, and there is no body rotation to power that swing. What created the power???

> Doug, are you agreeing with Teacherman? And what do you mean by hand strength? I assume you are not talking about grip strength as that does effect the swing. And I also assume that you talking about the strength of the player's forearm strength. Which to me correlates to wrist strenght, because the forearm controls wrist movement. And how does this forearm strength come into play? IMO, it has to come from the "whip" that Teacherman is talking about, where the hands are stopped are the wrists snap the bat around.

> As an aside, people have to start clearing up what they mean when they say "hands". The hands can do very little movement. The have very little power on their own. All they can basically do is grip and rotate around. I believe cues like "take your hands to the ball" came around because of hand-eye-coordination. But what really happens in that cue? The ARMS extend to the ball. Over the years people have tried to simplify the swing, so talk about the "hands" came into play. But when talking about the swing in detail (like on this board) you have to be more clear about what you are actually talking about.

I agree that strong hands are not nearly as important as strong forearms.
