Thanks.


Both aren't useful in isolation. Typically, I start counting when I see the "giddy-up" or the first significant blur. That's called "GO!". If I'm not counting based on that (i.e. counting an amateur swing), I use solid heel plant. You need to be careful though, since some hitters have 3 frames of heel plant.

Pay attention to what the hands are doing too, though.

Naah too restrictive. Some guys who don't stride ride up on that toe and really don't get the barrel moving until the heel drops.

I am fine with counting from solid foot plant. In fact sometimes I count from first evidence of the heel touching. Frankly I don't use the frame counting that much other than to make sure we aren't too slow. I have a 6-frame clip somewhere of Adrian Gonzalez. So it's a nice rule of thumb but probably nothing to sweat too much.
I don't necessarily agree Boston. Where the point of contact is tells you nothing about bat speed. And batspeed is what is needed to produce power numbers. A player could have a very slow bat and simply start the swing very early and still hit the ball out front. Ideally, you want a player that waits as long as possible and still hits it out front of the foot.
Hasn't someone on one of these sites made the statement that those elite home run hitting slo-pitch softball hitters have greater bat-speed than mlb hitters? (meaning measured in MPH). Of course they don't have to make location decisions in a split second so swing quickness is meaningless.

And I guess my point is bat speed is important of course but not everything. Another thing I thought I read on one of the debates was that Pujols MPH was one of the slowest measured on the Cardinals despite his tremendous power.

Mainly if the kid's rear leg is the driver, and it starts to turn while the back hip is still pulled around he's got the foundation of a good power swing. If this is setup right the kid will appear to get sat a little bit as his back leg drives forward.

What's just as critical as counting the frames to contact, it's sometimes valuable to watch a check swing and compare that to a ball you hit. How many frames could the player go in before he decided, no I am not going. If he can back off 2-4 frames before contact his swing quickness is solid.

Very well said.
