JWM37,
My instruction on throwing begins with the basic premise that the ball never travels faster then when it's in the air. I want to get my hands and feet into a powerful pre-throw position as fast as I can so when my front foot hits the ground I can explode and make the throw.
Since the legs are slower then the hands I need to be sure my footwork is as quick, yet as efficient as possible so my throw does not slow down to the speed of my legs.
My goal with my high school age and older catchers is to get them to a point in their mechanics where they achieve 95-97% of their max velocity out of their crouch. Their max velocity is probably out of a crow hop. When they get to this point then there is no need to take a step forward with the right foot and gain momentum since the additional time that will add to the throw will negate any possible increase in velocity.
Not only does the forward motion of the jab step take more time then a short pull straight across as I have explained earlier in this post, once the right foot hits the ground now the left hip is trailing the right hip when the left foot begins to drive to the target. Some additional amount of time will elapse just to get my hips even, let alone my left hip driving in front of the right hip. By coming straight across as I teach the hips stay even and as soon as the left side begins to move it is ahead of the right side.
If I can shave 1/10th of a second off a catchers release he has achieved what would have required a 5MPH velocity gain to achieve.
CC05 has also brought up the other points I have taught. Most players taking that jab step tend to get the top half out ahead of the legs and balance is sacrificed, and ultimately throwing efficiency.
